Biographical / Historical:
In 1832 Samuel F. B. Morse, assisted by Alfred Vail, conceived of the idea for an electromechanical telegraph, which he called the "Recording Telegraph." This commercial application of electricity was made tangible by their construction of a crude working model in 1835-36. This instrument probably was never used outside of Professor Morse's rooms where it was, however, operated in a number of demonstrations. This original telegraph instrument was in the hands of the Western Union Telegraph Company and had been kept carefully over the years in a glass case. It was moved several times in New York as the Western Union headquarters building changed location over the years. The company presented it to the Smithsonian Institution in 1950.
The telegraph was further refined by Morse, Vail, and a colleague, Leonard Gale, into working mechanical form in 1837. In this year Morse filed a caveat for it at the U.S. Patent Office. Electricity, provided by Joseph Henry's 1836 "intensity batteries", was sent over a wire. The flow of electricity through the wire was interrupted for shorter or longer periods by holding down the key of the device. The resulting dots or dashes were recorded on a printer or could be interpreted orally. In 1838 Morse perfected his sending and receiving code and organized a corporation, making Vail and Gale his partners.
In 1843 Morse received funds from Congress to set-up a demonstration line between Washington and Baltimore. Unfortunately, Morse was not an astute businessman and had no practical plan for constructing a line. After an unsuccessful attempt at laying underground cables with Ezra Cornell, the inventor of a trench digger, Morse switched to the erection of telegraph poles and was more successful. On May 24, 1844, Morse, in the U.S. Supreme Court Chambers in Washington, sent by telegraph the oft-quoted message to his colleague Vail in Baltimore, "What hath God wrought!"
In 1845 Morse hired Andrew Jackson's former postmaster general, Amos Kendall, as his agent in locating potential buyers of the telegraph. Kendall realized the value of the device, and had little trouble convincing others of its potential for profit. By the spring he had attracted a small group of investors. They subscribed $15,000 and formed the Magnetic Telegraph Company. Many new telegraph companies were formed as Morse sold licenses wherever he could.
The first commercial telegraph line was completed between Washington, D.C., and New York City in the spring of 1846 by the Magnetic Telegraph Company. Shortly thereafter, F. O. J. Smith, one of the patent owners, built a line between New York City and Boston. Most of these early companies were licensed by owners of Samuel Morse patents. The Morse messages were sent and received in a code of dots and dashes.
At this time other telegraph systems based on rival technologies were being built. Some companies used the printing telegraph, a device invented by a Vermonter, Royal E. House, whose messages were printed on paper or tape in Roman letters. In 1848 a Scotch scientist, Alexander Bain, received his patents on a telegraph. These were but two of many competing and incompatible technologies that had developed. The result was confusion, inefficiency, and a rash of suits and counter suits.
By 1851 there were over fifty separate telegraph companies operating in the United States. This corporate cornucopia developed because the owners of the telegraph patents had been unsuccessful in convincing the United States and other governments of the invention's potential usefulness. In the private sector, the owners had difficulty convincing capitalists of the commercial value of the invention. This led to the owners' willingness to sell licenses to many purchasers who organized separate companies and then built independent telegraph lines in various sections of the country.
Hiram Sibley moved to Rochester, New York, in 1838 to pursue banking and real estate. Later he was elected sheriff of Monroe County. In Rochester he was introduced to Judge Samuel L. Selden who held the House Telegraph patent rights. In 1849 Selden and Sibley organized the New York State Printing Telegraph Company, but they found it hard to compete with the existing New York, Albany, and Buffalo Telegraph Company.
After this experience Selden suggested that instead of creating a new line, the two should try to acquire all the companies west of Buffalo and unite them into a single unified system. Selden secured an agency for the extension throughout the United States of the House system. In an effort to expand this line west, Judge Selden called on friends and the people in Rochester. This led, in April 1851, to the organization of a company and the filing in Albany of the Articles of Association for the "New York and Mississippi Valley Printing Telegraph Company" (NYMVPTC), a company which later evolved into the Western Union Telegraph Company.
In 1854 there were two rival systems of the NYMVPTC in the West. These two systems consisted of thirteen separate companies. All the companies were using Morse patents in the five states north of the Ohio River. This created a struggle between three separate entities, leading to an unreliable and inefficient telegraph service. The owners of these rival companies eventually decided to invest their money elsewhere and arrangements were made for the NYMVPTC to purchase their interests.
Hiram Sibley recapitalized the company in 1854 under the same name and began a program of construction and acquisition. The most important takeover was carried out by Sibley when he negotiated the purchase of the Morse patent rights for the Midwest for $50,000 from Jeptha H. Wade and John J. Speed, without the knowledge of Ezra Cornell, their partner in the Erie and Michigan Telegraph Company (EMTC). With this acquisition Sibley proceeded to switch to the superior Morse system. He also hired Wade, a very capable manager, who became his protege and later his successor. After a bitter struggle Morse and Wade obtained the EMTC from Cornell in 1855, thus assuring dominance by the NYMVPTC in the Midwest. In 1856 the company name was changed to the "Western Union Telegraph Company," indicating the union of the Western lines into one compact system. In December, 1857, the Company paid stockholders their first dividend.
Between 1857 and 1861 similar consolidations of telegraph companies took place in other areas of the country so that most of the telegraph interests of the United States had merged into six systems. These were the American Telegraph Company (covering the Atlantic and some Gulf states), The Western Union Telegraph Company (covering states North of the Ohio River and parts of Iowa, Kansas, Missouri, and Minnesota), the New York Albany and Buffalo Electro-Magnetic Telegraph Company (covering New York State), the Atlantic and Ohio Telegraph Company (covering Pennsylvania), the Illinois & Mississippi Telegraph Company (covering sections of Missouri, Iowa, and Illinois), and the New Orleans & Ohio Telegraph Company (covering the southern Mississippi Valley and the Southwest). All these companies worked together in a mutually friendly alliance, and other small companies cooperated with the six systems, particularly some on the West Coast.
By the time of the Civil War, there was a strong commercial incentive to construct a telegraph line across the western plains to link the two coasts of America. Many companies, however, believed the line would be impossible to build and maintain.
In 1860 Congress passed, and President James Buchanan signed, the Pacific Telegraph Act, which authorized the Secretary of the Treasury to seek bids for a project to construct a transcontinental line. When two bidders dropped out, Hiram Sibley, representing Western Union, was the only bidder left. By default Sibley won the contract. The Pacific Telegraph Company was organized for the purpose of building the eastern section of the line. Sibley sent Wade to California, where he consolidated the small local companies into the California State Telegraph Company. This entity then organized the Overland Telegraph Company, which handled construction eastward from Carson City, Nevada, joining the existing California lines, to Salt Lake City, Utah. Sibley's Pacific Telegraph Company built westward from Omaha, Nebraska. Sibley put most of his resources into the venture. The line was completed in October, 1861. Both companies were soon merged into Western Union. This accomplishment made Hiram Sibley leader of the telegraph industry.
Further consolidations took place over the next several years. Many companies merged into the American Telegraph Company. With the expiration of the Morse patents, several organizations were combined in 1864 under the name of "The U.S. Telegraph Company." In 1866 the final consolidation took place, with Western Union exchanging stock for the stock of the other two organizations. The general office of Western Union moved at this time from Rochester to 145 Broadway, New York City. In 1875 the main office moved to 195 Broadway, where it remained until 1930 when it relocated to 60 Hudson Street.
In 1873 Western Union purchased a majority of shares in the International Ocean Telegraph Company. This was an important move because it marked Western Union's entry into the foreign telegraph market. Having previously worked with foreign companies, Western Union now began competing for overseas business.
In the late 1870s Western Union, led by William H. Vanderbilt, attempted to wrest control of the major telephone patents, and the new telephone industry, away from the Bell Telephone Company. But due to new Bell leadership and a subsequent hostile takeover attempt of Western Union by Jay Gould, Western Union discontinued its fight and Bell Telephone prevailed.
Despite these corporate calisthenics, Western Union remained in the public eye. The sight of a uniformed Western Union messenger boy was familiar in small towns and big cities all over the country for many years. Some of Western Union's top officials in fact began their careers as messenger boys.
Throughout the remainder of the nineteenth century the telegraph became one of the most important factors in the development of social and commercial life of America. In spite of improvements to the telegraph, however, two new inventions--the telephone (nineteenth century) and the radio (twentieth century)--eventually replaced the telegraph as the leaders of the communication revolution for most Americans.
At the turn of the century, Bell abandoned its struggles to maintain a monopoly through patent suits, and entered into direct competition with the many independent telephone companies. Around this time, the company adopted its new name, the American Telephone and Telegraph Company (AT&T).
In 1908 AT&T gained control of Western Union. This proved beneficial to Western Union, because the companies were able to share lines when needed, and it became possible to order telegrams by telephone. However, it was only possible to order Western Union telegrams, and this hurt the business of Western Union's main competitor, the Postal Telegraph Company. In 1913, however, as part of a move to prevent the government from invoking antitrust laws, AT&T completely separated itself from Western Union.
Western Union continued to prosper and it received commendations from the U.S. armed forces for service during both world wars. In 1945 Western Union finally merged with its longtime rival, the Postal Telegraph Company. As part of that merger, Western Union agreed to separate domestic and foreign business. In 1963 Western Union International Incorporated, a private company completely separate from the Western Union Telegraph Company, was formed and an agreement with the Postal Telegraph Company was completed. In 1994, Western Union Financial Services, Inc. was acquired by First Financial Management Corporation. In 1995, First Financial Management Corporation merged with First Data Corporation making Western Union a First Data subsidiary.
Many technological advancements followed the telegraph's development. The following are among the more important:
The first advancement of the telegraph occurred around 1850 when operators realized that the clicks of the recording instrument portrayed a sound pattern, understandable by the operators as dots and dashes. This allowed the operator to hear the message by ear and simultaneously write it down. This ability transformed the telegraph into a versatile and speedy system.
Duplex Telegraphy, 1871-72, was invented by the president of the Franklin Telegraph Company. Unable to sell his invention to his own company, he found a willing buyer in Western Union. Utilizing this invention, two messages were sent over the wire simultaneously, one in each direction.
As business blossomed and demand surged, new devices appeared. Thomas Edison's Quadruplex allowed four messages to be sent over the same wire simultaneously, two in one direction and two in the other.
An English automatic signaling arrangement, Wheatstone's Automatic Telegraph, 1883, allowed larger numbers of words to be transmitted over a wire at once. It could only be used advantageously, however, on circuits where there was a heavy volume of business.
Buckingham's Machine Telegraph was an improvement on the House system. It printed received messages in plain Roman letters quickly and legibly on a message blank, ready for delivery.
Vibroplex, c. 1890, a semi-automatic key sometimes called a "bug key," made the dots automatically. This relieved the operator of much physical strain.

This collection consists of the records of the Waco Aircraft Company. The material includes office files of the company, marketing and sales information, and design data. Also included are original engineering drawings and report files.
Scope and Contents note:
In 1920 Clayton J. Bruckner, Elwood "Sam" Junkin and George "Buck" Weaver formed Weaver Aircraft Co. In April of 1923, they renamed the company Advanced Aircraft Co. and, in May of 1929, Waco Aircraft Co. By the 1930s the company was a leader in the design of wood and fabric aircraft. At their most widespread use, Waco aircraft were operated by public, private, military and corporate owners in thirty-five countries. During World War II, Waco devoted itself entirely to war production, manufacturing large numbers of troop- and cargo-carrying gliders. Following the war Waco attempted to market a wholly new design, but the post- war slump in the private aviation market and the high development costs of the aircraft forced Waco to withdraw from aircraft manufacture in June 1947. During its twenty-seven year existence Waco produced sixty-two different aircraft models and led all its competitors in the number of aircraft registered.
The Waco collection is divided into two parts. Part One comprises 24,855 drawings. The locations and descriptive information of these drawings are listed on an electronic database entitled the Waco Aircraft Engineering Drawings Data Base. The drawings vary greatly in size from small drawings of 4x5" to large sheets of over 150" in length. The majority of the drawings included in Part One are numbered, but many of the drawings are unnumbered. These drawings span most of the Company's existence and depict many of its powered and glider aircraft. There are several smaller sets of drawings which include layout drawings, tool drawings and stress analyses. Production charts and data charts are also among these drawings.
Part Two includes the business records of the Waco Aircraft Company. These documents can be generally divided between the engineering and sales departments. Most of the drawings within Part Two are from sub-contractors and U.S. Government agencies.
Waco aircraft company designations are confusing. Many variations exist regarding the practice of assigning model designations. Despite these exceptions, some basic rules serve as a guideline. Prior to 1930, Waco models were designated by a single number, 1 through 10. The last aircraft designated in this manner, the Waco 10, became the Waco Model O under the new scheme of designation.
Waco early models were additionally referred to by their horsepower. This may have been a practice of distributors and salesmen.
Since 1930, The Waco Aircraft Company used a combination of three letters with which to name its models. An example would be the Model ASO. The letters are best read from right to left. The letter on the right represents the fuselage, i.e. Model O. The middle letter represents a modification to the basic model, i.e. CSO for straight wing or CTO for tapered wing. The letter on the left represents the engine, i.e. CSO for Wright J-6, 225 horse power engine. Additionally, Waco models were often followed by a number indicating the year in which the aircraft was built. A YPF-6, for example, was manufactured in 1936.
Waco World War II gliders, designed for the U.S.A.A.F, were designated by an alpha-numeric combination. The four unpowered gliders produced shared the same letter prefixes of CG, which stood for cargo glider. The numeric suffix distinguishes the aircraft. They were the Models CG-3A, CG-4A, CG-13A and CG-15A. An X preceding the designation denotes experimental, i.e. XCG-4A. An addition of two letters denotes the manufacturer, i.e. CG-4A- TI for Timm Aircraft Co. Many of the Waco designed gliders were constructed by various companies. Powered versions of the gliders were referred to by the prefix PG for powered gliders.

In 1920 Clayton J. Bruckner, Elmwood "Sam" Junkin, and Buck Weaver formed an aircraft company known as the Weaver Aircraft Company in Troy, OH. By the 1930s the company, known as Waco Aircraft Co. since 1929, was a leader in the design of wood and fabric aircraft, with Waco aircraft being operated by public, private, and corporate owners in thirty-five countries. During World War II Waco devoted itself entirely to war production, manufacturing large numbers of troop- and cargo-carrying gliders.

Collection documents the development of the Holter Monitor, a portable device for continuously monitoring heart activity for an extended period, through engineering logbooks, drawings, operator manuals, correspondence, photographs, sales brochures and catalogs, biographical information about the engineering staff who worked on the monitor, patents and trademarks, and marketing and sales materials.
Scope and Contents:
The collection includes engineering logbooks, drawings, operator manuals, correspondence, photographs, sales brochures and catalogs, biographical information about the engineering staff who worked on the monitor, patents and trademarks, and marketing and sales materials documenting the development of the Holter Monitor, a portable device for continuously monitoring heart activity.
The records document the successful collaboration of an independent inventor and a manufacturing firm to identify problems, develop solutions and bring to market diagnostic technologies. Bruce Del Mar's role as an innovator and collaborator with Holter is especially important, because Del Mar's work spurred the development of an entire diagnostic industry. In addition, the records also chronicle how "Holter technology" was affected by progressive technological innovations in the industry, as vacuum tubes were replaced by transistors, as microprocessors gave way to microchips and circuit boards, and as analog recordings were replaced by digital formats.
Documenting manufacturing developments (highs and lows) and marketing considerations is an important element in better understanding the invention process. Del Mar Avionics was the first to design and manufacture instrumentation for long-term monitoring of the human heart for the medical profession. Today, Holter Monitors continue to be an important diagnostic tool for monitoring the health of the heart.
Series 1, Historical Background, 1951-2010 and undated, consists of biographical materials for Bruce Del Mar, founder of Del Mar Avionics, company histories, copies of the Del Mar Avionics newsletter Pacemaker, employee information, newspaper clippings and ephemera, and photographs of some employees. The employee information contains a 1979 handbook, explaining company policies and the benefits of employment with Del Mar Avionics and a 1951 memo detailing overtime working hours for women, presumably from Douglas Aircraft, where Bruce Del Mar was employed.
Series 2, Del Mar Avionics Engineering, 1958-1976, is divided into three subseries, Subseries 1, Correspondence, 1965-1976; Subseries 2, Reports, 1964-1969; and Subseries 3, Drawings, 1958-1968. The documentation consists primarily of correspondence from the engineering department, 1965 to 1976, related to the development, design, budgeting, testing, and marketing of the Holter Monitor. The majority of the documentation is correspondence and is written by engineering staff members, but also included are quotation requests, trip reports, and technical reports. Correspondence between Holter and Del Mar about the development of the Holter Minotor is in Series 6. The drawings, 1958-1968, include six drawings (22" x 34" or smaller) for Avionics Research Products projects (panel assembly, chassis assembly, and battery chargers for model 602), and Electromation Company (degausser single coil).
Series 3, Patents and Trademarks, 1965-2002 and undated, consists of copies of patents by Norman J. Holter, W.E. Mills, and W.E. Thornton, Cliff Sanctuary. and Isaac Raymond Cherry related to the development of the Holter Monitor. Also included are lists of United States patents issued to Del Mar Avionics employees, as well as lists of registered trademarks and activities for Del Mar Avionics and copies of trademarks issued to the company.
Series 4, Product Literature, 1968-2010 and undated, consists of product literature for Del Mar Avionics products and some of its competitors. The product literature for Del Mar Avionics is arranged chronologically by model number, and the competitor literature is arranged alphabetically. All of the product literature is related to medical instrumentation with the exception of the Hydra Set, a precision load positioner which is the only product Del Mar Avionics sells today.
Series 5, Sales, 1967-1985, consists of price lists, price catalogs (both domestic and international) and sales objectives for medical instrumentation sold by Del Mar Avionics.
Series 6, Holter Monitor Materials, 1958-2005 and undated, is divided into three subseries, Subseries 1, Background Materials, 1958-2005 and undated; Subseries 2, Model 445, 1974-1978; and Subseries 3, Model 660, 1967-1978 and undated, and consists of materials documenting the relationship between Norman J. Holter, an inventor, and Del Mar Avionics.
Holter and Wilford R. Glassock were issued United States Patent 3,215,136 on November 2, 1965 for the Electrocardiographic Means. Dr. Eliot Corday introduced Holter to Bruce Del Mar, founder of the Del Mar Avionics Corporation in Irvine, California. Del Mar engineers developed the "electrocardiocorder" for clinical use, producing a commercially viable monitor which came to be known as the Holter Monitor Test. Further refinements led to the creation of a "minimonitor" in 1968 which was described by Holter as being the "size of a cigarette package." Commercial production of the Holter minimonitor, AVSEP, Jr., began in 1969. The Holter Research Foundation ultimately sold exclusive rights to their patents to Del Mar Engineering Laboratories.
The materials include biographical materials about Norman J. Holter, journal articles about the Holter Monitor, correspondence, engineering notebooks, a licensing agreement, product literature, reports, price lists, catalogs, operating manuals and specific information about the Dynamic Del Mar Avionics ElectroCardioCorder (Model 445), 1977, and the ElectroCardioScanner (Model 660), 1971. Both models were developed by Del Mar's medical device manufacturing staff. The licensing agreement and correspondence detail in chronological order the relationship between Norman Holter and Del Mar Avionics, specifically president Bruce Del Mar, in the rapid commercial marketing and development of Holter's electrocardiorecorder. Although Holter assigned exclusive rights to his patent to Del Mar Avionics, he was involved in the design and development process, albeit from a distance. The engineering staff at Del Mar kept Holter informed, and it is clear that Holter regularly visited the company.
The engineering notebooks relate to the models 445 and 660. The notebooks were maintained by engineering staff members D. Anderson, N. Mohammedi, Ray Cherry and Fike. The notebooks are handwritten, although in some instances memos and other information have been inserted. For example, N. Mohammedi's notebook documenting Model 445 contains black-and-white prints, magnetic tape samples, and recorder tape (EKG graph paper) samples with data from the monitor. The notebooks are bound and paginated, and individual pages are stamped sequentially.
Series 7, Slides, circa 1990s, consists of color slides used for presentations by Del Mar Avionics staff to discuss and promote the marketing of the Holter Monitor.
The collection is arranged into seven series.

Biographical / Historical:
Norman Jefferis "Jeff" Holter (1914-1983) was born in Helena, Montana, to a prominent Montana pioneering family. After attending public schools in Helena, he earned master's degrees in chemistry from the University of Southern California (1938) and physics from the University of California, Los Angeles (1940). During these years Holter also organized Applied Micro Sciences, a scientific photography business, and began working with Dr. Joseph A. Gengerelli of UCLA on nerve stimulation in frogs and brain stimulation in rats. Holter's interest in studying electrical activity in humans in their daily activities without touching them, spawned his lifelong pursuit to develop the Holter Monitor.
During World War Two, Holter served as a senior physicist for the U.S. Navy's Bureau of Ships, conducting research into the behavior of ocean waves in preparation for wartime amphibious operations. After the war, in 1946, Holter headed a staff of oceanographic engineers at Bikini Atoll during Operation Crossroads, the first postwar atomic bomb tests, measuring wave actions and underwater disturbances caused by the explosions.
Because of demands of his family's business affairs, Holter returned to Helena in 1947 to continue his research activities. In 1947 he formed the Holter Research Foundation, with a laboratory originally located in the rear of the Holter Hardware Company building. From 1956 to 1971 the laboratory facilities were located in the Great Northern Railroad depot building in Helena. The foundation was initially funded by Holter and other members of his family, but in 1952 Holter began to receive grants from the National Institutes of Health (NIH).
Holter continued his collaboration with Dr. Gengerelli of UCLA in attempting to transmit information, primarily brain waves, by radio. Holter turned his attention from the brain to the heart because the heart's greater voltage made the electronics easier, and because heart disease was far more prevalent than cerebral disease. Holter's introduction to Dr. Paul Dudley White (1886-1973), a renowned physician and cardiologist, helped convince him to focus his research on recording electrical activity from the heart. Holter's goal was to radio broadcast and record the more obvious electrophysiological phenomena occurring in humans while carrying on their normal activities, rather than having to lie quietly on a couch.
The first broadcast of a radioelectrocardiogram (RECG) took place circa 1947 and required eighty to eighty-five pounds of equipment, which Holter worn on his back while riding a stationary bicycle. This was not practical and in no way could be worn by a patient. The initial transmitter and receiver required that the subject remain in the general area of the laboratory, so a portable and lighter RECG receiver-recorder had to be developed.
Next, Holter created a briefcase-like device that could be carried by a patient. By using very thin magnetic recording tape, twenty-four hours of RECG could be captured on a reel five inches in diameter. The initial method of examining the voluminous records from the tape recordings developed by Holter was called Audio-Visual Superimposed ECG Presentation (AVSEP). AVSEP made it possible to examine twenty-four hours of RECGs in twenty minutes, with signals being presented visually on an oscilloscope and audibly through a speaker.
With the development of transistors, radioelectrocardiography was made obsolete, and it became possible for the amplifier, tape recorder, temperature-control circuits, motor speed control circuits, and batteries to be placed in a single unit small enough for a coat pocket or purse. In 1952, Holter succeeded in creating a small unit that weighed 1 kilogram. Wilford R. Glassock, a senior engineer working with Holter, traveled to Cedars of Lebanon Hospital (now Cedars-Sinai Hospital of Los Angeles) in 1962 to demonstrate the Holter monitor system and discuss making it more practical. At Cedars, Dr. Eliot Corday observed the practicality of the system and not only embraced the technology, but collaborated with Holter's team and was an early promoter of the technology to both industry and physicians. Holter and Glassock were issued US Patent 3,215,136 on November 2, 1965 for the Electrocardiographic Means.
As articles describing the foundation's invention of these devices began to appear in the professional literature, there was considerable demand from doctors and hospitals for the equipment. Dr. Corday introduced Holter to Bruce Del Mar, founder of the Del Mar Avionics Corporation in Irvine, California. Del Mar engineers developed the "electrocardiocorder" for clinical use, producing a commercially viable monitor which came to be known as the Holter Monitor Test. Further refinements led to the creation of a "minimonitor" in 1968, which was described by Holter as being the "size of a cigarette package." Commercial production of the Holter minimonitor, AVSEP, Jr., began in 1969. The Holter Research Foundation ultimately sold exclusive rights to their patents to Del Mar Engineering Laboratories.
Later known as Del Mar Avionics, a team of engineers diverted their attention from successful manufacturing of military weapons training devices to focus on improving the speed and accuracy of computerized ECG analysis and they became the acknowledged leader in Holter monitoring technology for over 40 years. In 1969, because of the increased amount of required paper work and red tape, Holter canceled the grant funding his foundation had been receiving from NIH. He was also in constant conflict with the Internal Revenue Service over the foundation's non-profit status, rights to patents, and commercial production of equipment. The foundation continued to maintain a laboratory and conduct varied scientific work, but on a much smaller scale. The Holter Research Foundation, Inc. was dissolved in 1985, two years after Holter's death.
Del Mar Avionics was founded on January 9, 1952, as Del Mar Engineering Laboratories in Los Angeles, California by Bruce Del Mar, who led the development of aircraft cabin pressurization systems. Del Mar was born in Pasadena, California in 1913. An engineer, inventor, entrepreneur and businessman, Del Mar graduated from the University of California, Berkeley (1937) with a Bachelor of Science degree. Del Mar worked for Douglas Aircraft (1933-1951) as a research engineer on many projects before founding Del Mar Engineering Laboratories. In 1938, Del Mar married Mary Van Ness. The couple had two daughters, Patrica Jean Parsons and Marna Belle Schnabel.
In 1958, Del Mar formed a wholly-owned subsidiary, Electromation Inc., which manufactured tape recording and communication equipment. He later established, Aeroplastics Corporation to manufacture plastic products and Avionics Research Products Corporation to develop and produce biomedical instrumentation. By the mid-1960s, the company had become a leading U.S. Defense Department prime contractor in the development and production of aerial tow target systems for weapons training and instrumented ground targets for scoring air-to-ground automatic weapons delivery. It also produced helicopter target drones and helicopter flight trainers for the U.S. Army.
In 1961, the company entered the growing medical instrumentation market with the development of the first long-term ambulatory monitoring systems.
In 1965, the company introduced the Hydra Set Load Positioner that controls the precise vertical positioning of loads up to 300 tons (272,000 kg) in increments as small as 0.001 inch (0.025mm). This unique product, mounted between the load and the crane (or hoist), permits precise mating and de-mating of critical components, thus eliminating unforeseen damage to valuable loads. Hydra Set Load Positioners are in use worldwide in the aerospace, military/commercial aviation, nuclear and fossil fuel power generating industries and in various industrial applications. In 1975, the company, then re-named Del Mar Avionics, moved to its current location in Irvine, California.

Biographical / Historical:
Samuel Pierpont Langley (1834-1906) was an astronomer, a pioneer of aeronautical research, and Secretary of the Smithsonian Institution (1887-1906). As a young man, Langley studied civil engineering and pursued this as a career until 1864, when his interest in astronomy led him to positions at the Harvard Observatory, the Naval Academy, the Western University of Pennsylvania and the Allegheny Observatory in Pittsburgh. In 1887, Langley was named Secretary of the Smithsonian, and spent the following years in the research, construction and tests of flying machines. On May 6, 1896, his unpiloted Aerodrome No. 5, powered by a 1hp steam engine, flew nearly three quarters of a mile. This flight surpassed by more than ten times the best efforts of any predecessor. In 1898, at the request of the Army's Board of Ordnance and Fortifications, Langley started work on another design - the Great Aerodrome, also known as Aerodrome A. However, two attempts at launching the aircraft in 1903 failed. In addition to his scientific experiments, Langley's writings include Experiments in Aerodynamics and The Internal Work of the Wind, and the Langley Memoir on Mechanical Flight, published posthumously. Samuel P. Langley died in Aiken, South Carolina, on February 27, 1906.

It has a fifty foot wing span, and is equipped with a lightweight 20-horsepower steam engine of Ader's design and a four-bladed propeller. At Armainvilliers on October 9, the Éole lifts off the ground to an altitude of approximately one foot and skims the ground for about 50 meters (165 feet). Ader later claims a second flight of 100 meters in September, 1891; there is no evidence for the second flight.
March 28, 1891 -- First successful flight of one of Langley's rubber-powered models.
1891 -- Work begins on Langley's "Aerodrome No. 0", powered by two small steam engines. Construction is halted before the aircraft is completed.
1891 -- Otto Lilienthal, a German mechanical engineer, begins a program of flight research using piloted hang gliders of his own design. He and his brother Gustav will go on to design and build 18 gliders over the next five years, making approximately 2,000 flights.

1895 -- James Means publishes the first of his three >Aeronautical Annuals.
May 6, 1896 -- "Aerodrome No. 6" is launched from the houseboat's catapult; the left wing collapses and the aircraft lands in the water. Aerodrome No. 5 is launched at 3:05 PM and flies about half a mile in a minute and a half at an altitude reaching 100 feet – the first sustained flight of a heavier than air apparatus. In a second flight at 5:10, Aerodrome No. 5 makes three circles, climbs to about 60 feet, and is airborne for one minute and thirty-one seconds. The flight is witnessed and photographed by Alexander Graham Bell (box 45, folder 9).
June 1896 -- Chanute and Augustus Herring establish a camp at the Lake Michigan dunes near Miller, Indiana to conduct flight tests on a number of gliders – several of Chanute's designs, including his multiwing "Katydid", Herring's copy of a Lilienthal design, and a Chanute-Herring triplane collaboration.
August 9, 1896 -- Lilienthal's glider stalls and crashes from an altitude of about 50 feet. Lilienthal dies of his injuries the next morning. His last words are "Opfer müssen gebracht warden" - "Sacrifices must be made".

March 25, 1898 -- Assistant Secretary of the Navy Theodore Roosevelt suggests the military use of the Langley "Aerodrome" to Navy Secretary John D. Long (box 40, folder 10).
April 6, 1898 -- Langley proposes a scaled-up version of the "Aerodrome" for military use to a joint Army-Navy board meeting at the Smithsonian. He requests $50,000 to build a large, piloted version of his earlier designs. The proposed aircraft is called the "Great Aerodrome", or "Aerodrome A".
June 1898 -- Charles M. Manly, a Cornell University engineering student, is hired as Langley's "assistant in charge of experiments".
October 1898 -- Major work begins on the "Great Aerodrome", also known as "Aerodrome A".
December 12, 1898 -- A contract is signed between Langley and Stephen M. Balzer of New York. Balzer is to design and build a 12 horsepower motor to power the "Aerodrome". On the same date, Langley writes to the U.S. Army Board of Ordnance and Fortifications, agreeing to design and build a flying machine. He estimates a cost of $50,000 to build his machine.
May 1899 -- A new, larger houseboat equipped with a turntable and catapult is delivered in Washington.
May 30, 1899 -- Wilbur Wright sends a letter to Langley at the Smithsonian, requesting material pertaining to aeronautical research. He says in his letter that he wishes "… to begin a systematic study of the subject in preparation for practical work." Assistant Secretary of the Smithsonian Richard Rathbun directs his staff to assemble a package of papers, including Langley's Story of Experiments in Mechanical Flight and Experiments in Aerodynamics. The Wright brothers receive the package three weeks later. They later credit the material they received from the Smithsonian with giving them a "good understanding of the nature of the problem of flying."

October 2, 1899 -- Percy Pilcher dies of his injury after his Lilienthal-type glider breaks up in flight.
May 1900 -- Langley and the staff of the Smithsonian Astrophysical Observatory observe the May 28 solar eclipse in Wadesboro, North Carolina.
August 1900 -- The Wrights begin to build their first glider, a biplane design with a 17 foot wingspan.
September 1900 -- The Wrights arrive at Kitty Hawk, North Carolina, to test their glider on the dunes. They begin test flights in early October.
July 1901 -- The Wrights return to Kitty Hawk with a new biplane glider.
August 1901 -- Langley creates the Children's Room, with exhibits designed to inspire interest in science, technology and natural history, in the Smithsonian Castle.
Autumn 1901 -- The Wright brothers return to Dayton and begin a program to develop their own fundamental aeronautical data, building a wind tunnel and a test rig mounted on a bicycle.
September 19, 1902 -- The Wrights complete assembly of their new glider and begin flights the same afternoon. They continue the flights through the autumn. After an early crash, continual modifications improve the design. Wilbur writes to his father, "We now believe the flying problem is really nearing its solution." On their return to Dayton, the brothers file a patent on their design.
July 14, 1903 -- The houseboat is towed down the Potomac to a spot opposite Widewater, Virginia, about 40 miles from Washington.
August 8, 1903 -- Langley's "Quarter-Size Aerodrome" makes a successful flight from the houseboat.
September 3, 1903 -- Work is begun on erecting the "Great Aerodrome" on the houseboat catapult.
October 7, 1903 -- The "Great Aerodrome", piloted by Manly, is launched by the houseboat catapult at 12:20 PM. The aircraft is snagged by the catapult launch car, and drops into the river. Langley was in Washington, and does not witness the attempt. The wreckage of the "Aerodrome" is salvaged.
December 8, 1903 -- The refurbished "Great Aerodrome" is readied for flight on the houseboat, now moored below Washington at Arsenal Point at the confluence of the Potomac and Anacostia rivers. At 4:45 PM, the aircraft, with Manly at the controls, is launched. The tail assembly drags along the launch track, and the "Aerodrome's" tail begins to collapse. The "Aerodrome" drops into the river. Manly is briefly trapped by the wreckage, but cuts himself free and is rescued. In the aftermath of the crash, Langley is ridiculed in the press. Though the Army withdraws its support, Langley receives offers of financial support from businessmen to continue his aeronautical work. He politely refuses these offers and ends his aeronautical activities.
December 17, 1903 -- The Wright brothers make four flights at Kitty Hawk, North Carolina. The first flight covered a distance of 120 feet and lasted 12 seconds; in the fourth flight, the "Flyer" traveled 852 feet in 59 seconds.
June 1905 -- The Smithsonian's accountant, W. W. Karr, is accused of embezzling Institutional funds. He is later convicted and imprisoned. Langley holds himself responsible for the loss, and thereafter refuses to accept his salary.
November 1905 -- Langley suffers a stroke.
February 1906 -- Langley moves to Aiken, South Carolina to convalesce.
February 27, 1906 -- After suffering another stroke, Langley dies.
March 3, 1906 -- Samuel Pierpont Langley is buried in Forest Hill Cemetery, Boston.
May-October 1914 -- The "Great Aerodrome" is refurbished and is tested on Lake Keuka, Hammondsport, New York; the tests are conducted by Glenn Curtiss. Using the Manly-Balzer motor and mounted on pontoons instead of using a catapult launch, the "Aerodrome" makes several short flights, the longest lasting about five seconds. Later a Curtiss 80-hp engine is substituted for the Manly-Balzer motor and a flight of about 3,000 feet is made on September 17. The Smithsonian Institution later displays the "Aerodrome" with an exhibit label that reads "The first man-carrying aeroplane in the history of the world capable of sustained free flight." This claim causes a rift between the Institution and Orville Wright (Wilber Wright had died in 1912) that is not fully mended until 1942. The Wright 1903 "Flyer" is presented to the Smithsonian Institution on December 17, 1948. Today, the "Flyer" is on exhibit in the Milestones of Flight Gallery of the National Air and Space Museum's Mall Building; Samuel Langley's "Great Aerodrome" is displayed at the Museum's Steven F. Udvar-Hazy Center in Chantilly, Virginia.

F. C. Bache -- Laborer with the U.S. Fish Commission, then located at the Smithsonian.
Carl Barus -- Formerly of the U.S. Geological Survey and the Weather Bureau. Hired in 1893 as a physicist; acted as the liaison between Langley and the Aerodrome project staff. Part of the crew on the houseboat.
Louville Eugene Emerson -- Laborer.
George L. Fowler -- An engineer, Fowler was hired by Langley to help design an engine for the Aerodromes.
William Gaertner -- Instrument maker.
Heed, Jr. -- Name found in a shorthand diary dated 1899 - presumably, a Smithsonian secretary or assistant.
Augustus Moore Herring -- An independent aeronautical experimenter and skilled designer and pilot of gliders; hired by Octave Chanute in 1894 and by Langley as chief assistant in 1895. Herring resigned (or was dismissed) in November 1895 and resumed work with Chanute. In 1908, he competed with the Wrights for the Army Flyer contract, but did not complete a finished aircraft.
Edward Chalmers Huffaker -- An engineer and aeronautical experimenter; built gliders based on the observation of bird flight; had delivered a paper at the International Conference on Aerial Navigation in Chicago, 1893. Recommended by Chanute, Huffaker was hired by Langley in December, 1894. He resigned from the Smithsonian in 1898 and went to work for Chanute.
L. C. Maltby -- Machinist, 1891-1899; assisted in motor design and oversaw the fabrications of the metalwork for the Aerodromes. Part of the crew on the houseboat.
Charles Matthews Manly -- Graduate of Cornell University (1896). Hired by Langley and placed in charge of construction of the Great Aerodrome in 1898. Piloted the Great Aerodrome on its two launch attempts, 1903. Manly resigned from the Smithsonian in 1905. He served as a consulting aviation engineer for different government agencies and corporations, including the British War Office, 1915; the Curtiss Aeroplane and Motor Corporation 1915-1919 (from 1919-1920 as the assistant general manger); and as a member of the US Commission to the International Aircraft Conference, London, 1918. Manly also completed and edited Langley's Memoir on Mechanical Flight which was published by the Smithsonian in 1911.
Charles B. Nichols -- Smithsonian cabinet maker (1890-1893), in charge of construction of the small rubber powered models.
R. Luther Reed -- Smithsonian carpenter foreman (1880-1904). In charge of construction of Aerodromes No. 5 and 6 following between Herring's departure and Manly's arrival. Worked on design of the Great Aerodrome and the second houseboat. Part of the crew on the houseboat.
B.L. Rhinehart -- Smithsonian mechanic. Built a small steam motor for Aerodrome No. 0 in 1891. Performed design work on an experimental gasoline motor, c.1896.
William L. Speiden -- Draftsman or designer (1893-1899).
John Elfrith Watkins -- Assistant engineer of construction with the Pennsylvania Railroad. Joined the Smithsonian as an honorary curator in the Steam Transportation section in 1885. Named curator of Transportation in 1887. He rejoined the Pennsylvania Railroad in 1892, and later worked at the Field Columbian Museum as director of Industrial Arts. Watkins returned to the Smithsonian in 1895 as the National Museum's curator of Technological Collections. In 1898, he was named curator of the Division of Technology. Watkins also served the Smithsonian as Engineer of Property, 1888-1889, and Chief of Buildings and Superintendence, 1896-1903. Watkins carried on much of the Aerodrome project's correspondence, and was the project's expert in steam engine design.
George B. Wells -- Smithsonian messenger (1894-1903). Most of the collection's shorthand notebooks (Series X) bear his name; possibly, he acted as Langley's stenographer.
William Crawford Winlock -- Curator, Bureau of International Exchange (1889-1899).
Parts of the collection were separated at undetermined dates from the institutional records of Samuel Langley's time as Secretary (now held by the Smithsonian Institution Archives [SIA], as the Samuel P. Langley Papers, 1867-1906, Record Unit 7003).
In addition to Record Unit 7003, researchers may wish to consult these Smithsonian Institution Archives' collections:
Record Unit 31, Office of the Secretary, Correspondence, 1866-1906, with related records to 1927.
Record Unit 34, Office of the Secretary, Correspondence, 1887-1907
Record Unit 7268, J. Elfreth Watkins Collection, 1869, 1881-1903, 1953, 1966 and undated.
The Archives Division of the National Air and Space Museum holds the Charles M. Manly Papers, (Acc. 1999-0004). Manly was Samuel Langley's assistant in the Aerodrome project from 1898 to 1903.
Langley Technical Files: The Archives Division's technical files are housed in the Archives-Library reading room of the Museum's Steven F. Udvar-Hazy Center. Material on Langley and his Aerodromes are housed in folders in the technical files Aircraft Series and in the Biographies Series. Because material from the Samuel P. Langley Collection is thought to have been transferred into the Technical Files, these file headings are included here. In the listings, "Images Available" refers to digital image files available through the Archives Division's image database; these images may be viewed in the Museum's reading rooms.

This collection consists of over nine cubic feet of material documenting Scott Crossfield's aviation career, with emphasis on his involvement with the North American X-15. The following types of material are included: correspondence; reel to reel tapes; papers, manuscripts; newspaper and magazine clippings; aviation manuals; photographs; film; and Crossfield's notes and reports.
Scope and Content note:
This collection encompasses the entirety of Albert Scott "Scotty" Crossfield, Jr.'s career as an engineer, test pilot, airline executive, and speaker and advocate for aerospace education. Records in the collection date from Crossfield's time at college in the 1940s through his death in 2006. Crossfield's papers were donated to the National Air and Space Museum (NASM) Archives by the Crossfield family in 2006 and a second batch of material was received in 2008. The collection was received without any apparent organizational scheme, but some items were received in labeled folders and these folder titles were retained when the collection was processed. One group of material was loaned by the family for copying and these items were photocopied and placed within the appropriate folder in the case of documents, or were scanned and entered into the National Air and Space Museum (NASM) Archives image database in the case of photographs.
After his retirement from North American Aviation, Inc., Crossfield gave his papers to a former secretary, Marion Brown, so that she could organize them for his use in future writing projects. In February 1973, a U.S. Navy Vought A-7E Corsair II crashed into the apartment building where Brown lived and all of Crossfield's papers in her possession were destroyed. Due to this incident, the collection has more material from Crossfield's time with Eastern Airlines and onwards, although the prior years are still well represented through records that were either retained in Crossfield's possession or copies that were gathered after the fact. There is correspondence from Crossfield relating to the crash in Box 11 of the collection.
The archival materials in this collection are organized into four series. The first series is composed of personal materials and includes school records, correspondence, personal photographs, records relating to various organizations in which Crossfield was active, information relating to the publication of Crossfield's autobiography, Always Another Dawn, other writings by Crossfield, financial records, subject files assembled by Crossfield, philatelic materials (Crossfield was an active collector and was a founding member and officer of The Aviation Historical Foundation, a philatelic organization), and news clippings. The material in this series is largely organized chronologically. Personal photographs and subject files are organized by topic first and chronologically within each folder and organizations are arranged alphabetically by name first and also chronologically within the individual folders.
The second series contains items relating to Crossfield's professional life, organized chronologically by place of employment. This series includes materials relating to Crossfield's work at Boeing, the U.S. Navy, the Kirsten Wind Tunnel at the University of Washington Aeronautical Laboratory, the National Advisory Committee for Aeronautics (NACA), North American Aviation, Inc., Eastern Airlines, Hawker Siddeley Aviation, Crossfield's work as an Independent Technical Advisor, Crossfield's application for the position of Director of the National Air and Space Museum, Crossfield's time as a member of the United States Organizing Committee, and his work with organizations such as the Scott Crossfield Foundation and The Wright Experience. During the later part of his life, Crossfield toured the country extensively giving speeches, presenting awards, etc. and there is a large amount of material relating to these appearances in this part of the collection. These materials arrived already organized chronologically by individual trip and this organizational scheme was retained. Specifically, the professional life series includes flight reports, manuals, drawings, business correspondence, administrative records, presentations and papers, travel itineraries, notebooks, calendars, speeches delivered by Crossfield, and career related photographs (which are broken out as their own subseries). The professional life series also includes a section of miscellaneous professional items including job seeking correspondence, information on the patent for a power wheel braking or driving unit designed by Crossfield, and a folder of Crossfield's résumés.
The third series consists of audiotapes and is organized first by tape format and then chronologically within each category. Subjects of the audiotapes include speeches, a large number of North American X-15 cockpit recordings and radio communications, tape produced for a television program, and autobiographical notes. A number of the audiotapes include no description. With a total of 65 examples in this series, the most common audiotape format in the collection is, by far, 7 inch reel to reel tapes. Other formats in this series include 5 inch reel to reel tapes, 3.125 by 3.5 inch metal audiotape cartridges, and Dictaphone recording belts. Please note that these audio recordings are unavailable to the researcher at the time of processing due to the format and fragility of the tapes.
The fourth series of this collection is comprised of oversized materials including galley proofs, news clippings, drawings, charts, professional records, and photographs. The organization of this series mirrors the folder titles found in the rest of the collection.
The researcher should note that the collection also contains several motion picture films relating to the life and career of Albert Scott "Scotty" Crossfield, Jr. These films are not included in the container list but a NASM Archives staff person can assist you regarding access.

Albert Scott "Scotty" Crossfield, Jr. was born on October 2, 1921, in California. As a young boy, Crossfield was often confined indoors due to health problems related to pneumonia and rheumatic fever. During this time, he dreamed of becoming a pilot and designed and constructed model airplanes. Crossfield took his first airplane ride in 1927, at six years old, in an Alexander Eaglerock A-1 piloted by family friend Charles "Carl" Lienesch. Lienesch also encouraged Crossfield to become an engineer as well as a pilot. Unbeknownst to Crossfield's parents, he began taking flying lessons at the age of 12 at Wilmington Airport under the tutelage of pilot Vaughn McNulty. The family later moved to Washington State and it was there, at the Chehalis Airport, that Crossfield made his first solo flight in a Curtiss Robin. It was not until the summer of 1941, however, that Crossfield officially soloed and earned his pilot's license under the Civil Aeronautics Authority (CAA), Civilian Pilot Training Program (CPTP).
Crossfield enrolled in the University of Washington in 1940 and worked at the Boeing plant in Seattle, beginning in the fall of 1941, while still pursuing his studies. Crossfield's first assignment at Boeing was as an assembly page clerk. He was later promoted to the position of production expediter and shop salvage engineer. After the bombing of Pearl Harbor in December 1941, Crossfield enlisted in the U.S. Army Air Corps and continued to work at Boeing while he waited for an opening in a cadet class. In February 1942, tired of waiting on the Air Corps and eager to get into combat, Crossfield enlisted in the U.S. Navy instead where he joined the cadet class of May 7, 1942. Crossfield first trained in Seattle, Washington, and later was sent to the Naval Air Training Center in Corpus Christi, Texas, where he earned his Naval Aviator's wings in 1942. During his time in the Navy, Crossfield never fulfilled his ambition to see combat because he was selected instead to remain at Corpus Christi as a flight and gunnery instructor. Crossfield eventually was sent to Hawaii to prepare and train for an invasion of Japan but the war ended before this became necessary. During his time in the U.S. Navy, Crossfield flew the Grumman F6F Hellcat, Vought F4U Corsair, and the North American SNJ Texan, among other aircraft. After he separated from active duty with the Service, Crossfield remained active in the Naval Reserves and was part of an aerobatic team at Sand Point Naval Air Station that flew Goodyear FG-1D Corsairs.
Crossfield returned to his studies at the University of Washington in 1946 and was employed doing tests at the Kirsten Wind Tunnel at the University's Aeronautical Laboratory. Crossfield earned his Bachelor of Science degree in aeronautical engineering in 1949 and his master's degree in aeronautical science in 1950. After obtaining his degrees, Crossfield joined the National Advisory Committee for Aeronautics (NACA) as a research pilot. During his time with NACA, Crossfield flew many aircraft including the Convair XF-92A, Bell X-1, Northrop X-4 Bantam, Douglas D-558-1 Skystreak, Bell X-5, Republic F-84F Thunderstreak, Convair F-102 Delta Dagger, North American F-86 Sabre, and the North American F-100A Super Sabre. Crossfield made history in the Douglas D-558-2 Skyrocket on November 20, 1953, as the first pilot to exceed Mach 2 (twice the speed of sound).
In 1955, Crossfield left NACA and joined North American Aviation, Inc. to work on the X-15 program where he would not only serve as the X-15 Project Pilot but also as a Design Specialist, a role in which he was an integral part of the design of both the aircraft and the pressure suit developed by the David Clark Company for the X-15 program. The suit served as a prototype for the spacesuits later worn by astronauts. Crossfield helped to develop the X-15's cockpit, control, and engine systems; structural design; propulsion system; engineered its escape system; and contributed to its handling quality requirements. He also developed the ground control test methodology that would later become standard on the Mercury, Gemini, and Apollo space programs. Crossfield piloted the North American X-15 on its first captive flight in March 1959, first glide flight in June 1959, and the first powered flight in September 1959, as well as numerous other test flights, before the X-15 was delivered to the U.S. Air Force (USAF) and the National Aeronautics and Space Administration (NASA) in February 1960. Crossfield also served as Chief Engineering Test Pilot at North American from 1955-1961 before moving to the Space and Information Systems Division first as the Director of Systems Test (1961) then as the Division Director of Test and Quality Assurance (1961-1966) where he was responsible for quality control in all North American projects including the Hounddog Missile (AGM-28, GAM-77), Paragliders for the Gemini program, Apollo Command and Service Module, and the Saturn V launch vehicles, second stage. Crossfield's final position with North American was as the Technical Director, Research, Engineering and Test from 1966-1967.
Crossfield joined Eastern Airlines in Miami, Florida, as Division Vice President, Flight, Research, and Development, Flight Operations in 1967, a position he held until 1971 when he moved to Washington, DC, to serve as Staff Vice President, Transportation Systems Development (1971-1973). From 1974 to 1975, Crossfield served as Senior Vice President at Hawker Siddeley Aviation's U.S. subsidiary branch, an office he helped to establish. After leaving Hawker Siddeley, Crossfield served for many years as an independent technical advisor to the U.S. Congress. Crossfield also served on the United States Organizing Committee to plan the Air and Space Bicentennial. In the later part of his life, Crossfield traveled extensively to give talks, attend events, and make various professional appearances and it was on a return flight home from one such trip in 2006 that Crossfield was killed when the plane he was piloting was caught in a thunderstorm.
Crossfield was active in various organizations including the American Institute of Aeronautics and Astronautics (AIAA), the National Aeronautic Association (NAA), and the Society of Experimental Test Pilots (SETP), a group in which he was a founding member. Crossfield also created the Scott Crossfield Foundation to support aerospace education. Crossfield was the recipient of numerous awards and honors including the Sperry (Lawrence B.) Memorial Award (1954) and Chanute (Octave) Award (AIAA, 1958), Kincheloe Award (SETP, 1960), Harmon Trophy (1960), Collier (Robert J.) Trophy (1961), NASA Distinguished Service Medal (1993), and the National Air and Space Museum (NASM) Trophy for Lifetime Achievement (2000).
Crossfield published his autobiography, Always Another Dawn, in 1960 with Clay Blair, Jr. and is the author of numerous other publications, articles, and technical papers.

This collection is composed of Krafft Ehricke's files including Ehricke's published and unpublished papers as well as papers and works by others that Ehricke gathered, presumably as reference material.
Scope and Contents:
This collection consists of Krafft Ehricke's writings and interviews spanning 1949-1984 and items gathered by Ehricke as reference material for his various writing projects. The files on his writings include handwritten manuscripts, typed drafts, publication proofs, and/or final published versions and reprints, and in some cases include correspondences or other documents relating to publication. The collection also includes original paste-up versions of graphics created by or for Ehricke to illustrate his writings. The reference material includes technical reports, scientific papers, and newspaper and magazine articles gathered by Ehricke during his career.
The collection remained in the possession Ehricke's family for nearly two decades after his death and apparently was largely unorganized prior to processing. The material has been arranged in five series, with oversized materials filed at the end of the collection in series order by size.
Series I. Writings (Boxes 1-80) – copies of papers, articles, and lectures by Ehricke, including a mix of manuscript (MS), typescript (TS), paste-up, and published copies. Reports written by Ehricke as part of a study conducted as part of his professional duties are filed in Series IV as part of the "Studies and Projects" section of each subject group (see below). The materials are organized chronologically with different versions of the same work filed together by date of publication (if published) or completion. Ehricke rarely labeled MS or TS pages by title, generally wrote on the similar topics, and often cut finished text blocks or figures from one paper to use in another, a process he referred to cannibalization. As a result, although efforts have been made to organize loose MS and TS pages by their final works these assignments must be considered tentative and some pages have been left unassigned due to lack of sufficient information.
Series II. Graphics (Boxes 81-94) – copies of original and paste-up graphics (charts, graphs, illustrations) designed or created by Ehricke. Because these materials were mainly found in their original folders, they have been filed consistent with their original labeling. As a result they fall into groups roughly corresponding to Ehricke's tenures at General Dynamics, North American Rockwell, and Space Global.
Series III. Company Files (Boxes 94-104) – files and materials relating to business activities at the various companies for which Ehricke worked, organized by company in chronological order of Ehricke's tenure. Within each company, materials are organized by named files (filed alphabetically) and proposals and related material (filed chronologically). The proposals filed in this series represent studies or programs for which no other documentation exists in the collection.
Series IV. Reference Files (Boxes 104-253) – files and documents arranged by broad subject areas, based upon the subject organization for Ehricke's existing lecture transparencies. Within each subject area files are organized into three groups: named files (arranged alphabetically); studies (arranged chronologically by the start of the study); and other reports (arranged chronologically). Named files usually contain a variety of papers, reports, and articles and sometimes include items written by Ehricke. Studies often include correspondence, papers, or reports by Ehricke in addition to documents by other members of the study team; items by Ehricke have been filed in this series, rather than in Series I to preserve the context in which they were created and used. Other reports are generally filed chronologically by date of publication unless it could be clearly established that Ehricke acquired the material significantly later than its publication date (for instance: in cases where order forms attached to document bundles show that Ehricke had requested copies of the documents a decade after they were published). The subject areas are:
2. General (Boxes 104-108)
3. Vehicle Technology (Boxes 108-154)
4. Planets and Planetary Missions (Box 154-203)
5. Transportation Systems (Boxes 204-208)
6. Space Habitation and Human Factors (Boxes 208-219)
7. Space and Lunar Industry (Boxes 219-229)
8. Earth / Resources / Open World Synthesis (Boxes 229-234)
9. Energy (Boxes 234-249)
10. Space Light (Boxes 249-250)
11. Information Services (Boxes 250-253)
Unfortunately, there is significant overlap between these subject areas, especially between subseries 2, 3, 4, and 5; subseries 5, 6, and 9; and subseries 7, 8, and 9. Researchers are cautioned to examine several subject areas.
Series V. Miscellaneous Personal and Posthumous Materials (Boxes 253-254) – files and documents not otherwise related to Ehricke's research and writing or which post-date his death.
Krafft Arnold Ehricke (1917-1984) was an engineer and scientist who made vital contributions to the American space program. Ehricke was considered "one of the few philosophers of astronautics" by the early 1960s (note 1) and until his death remained a visionary and public champion of the cause of space exploration and colonization.
Ehricke was born in Berlin, Germany on 24 March 1917. He was inspired by Fritz Lang's 1929 science fiction film Frau im Mond (Woman in the Moon) and attempted to join the German rocket society, Verein für Raumschiffarht (VfR), but, denied membership due to his youth, he instead conducted his own experiments. He spent two years (1936-1938) fulfilling military service requirements in Germany's new Panzer Corps, then earned an Aeronautical Engineering degree (MS equivalent) from the Technical University of Berlin (1938-1940). With World War II underway, Ehricke was recalled to service and was wounded during the Blitzkrieg on the Western Front in 1940. While recuperating from his wound he took graduate courses in Celestial Mechanics and Nuclear Physics from the University of Berlin (1940-1941). He returned to duty in 1941 as an officer to participate in the German attack on Russia. In 1942 he was again wounded, but his earlier engineering work had come to the attention of Wernher von Braun and he was recruited into von Braun's rocket development team, a move he later credited with saving his life. Ehricke spent the next two years (1942-1944) as a propulsion engineer at Peenemünde, then became an ordnance lecturer in Köslin, Germany (now Koszalin, Poland) until the end of the war. In January 1945 Ehricke married Ingeborg Maria Mattull. As the Third Reich collapsed in May he returned to her in Berlin and went into hiding to escape being "recruited" by the Soviet Union. He was finally located by an American officer in 1946 and was reunited with von Braun and the other Operation Paperclip (note 2) scientists under United States Army auspices.
In January 1947 Ehricke began work as a Research Engineer for the Research and Development Service of the United States Army Ordnance Corps at Ft. Bliss, TX, moving to Huntsville, AL, in 1950 when the Army transferred missile development from Ft. Bliss to Redstone Arsenal, AL. In 1952 Ehricke was recruited by Walter Dornberger (note 3), left government service for private industry, and moved to Buffalo, NY, to work as a Design Specialist at Bell Aircraft. For the next two years he worked on Bell's Orbital Glider project, a precursor to Project Dyna-Soar, the Air Force reusable boost-glide weapon system that itself prefigured NASA's Space Shuttle.
In November 1954 Ehricke moved to San Diego, CA, to begin a decade-long career with what was then the Convair Division of General Dynamics. For several years he was a key figure in the development of the Convair's SM-65 Atlas ICBM and Atlas launch vehicle. NASA used the man-rated Atlas LV-3 for the orbital flights of the Mercury Program and as of this writing the Atlas V family of Evolved Expendable Launch Vehicles remains a mainstay of the United States launch vehicle inventory. Between 1959 and 1962 Ehricke directed the development of the Centaur booster, the first high-energy upper stage powered by liquid hydrogen. Although Centaur was not successfully launched until 1965, it eventually served as the upper stage for Atlas, Titan, and Delta launch vehicles and was the last stage for the Viking (Mars) and Voyager (Outer Planets) missions. During this time he also authored Space Flight, a two-volume textbook on celestial mechanics and launch vehicle design (note 4). In 1962 Ehricke became the director of the Advanced Projects Department of General Dynamics Astronautics, where he directed and contributed to studies of next-generation (Post-Saturn) launch vehicles and propulsion systems, planetary exploration programs, and post-Apollo space activities.
At the end of October 1965 Ehricke left General Dynamics to become the assistant director of Astrionics at the Autonetics Division of North American Aviation (note 5), later rising to become Chief Scientist in the Advanced Systems Department of North American Rockwell's Space Division (1968-1973) and Chief Scientific Advisor for Rockwell International's North American Space Operations (1973-1977). While at North American Ehricke was involved in some aspects of the Space Shuttle program but primarily worked advanced project studies, including studies relating to NASA's space station and deep space exploration programs, and culminating in a multi-year study of space industrialization which began in 1976. During this time he also acted as scientific advisor to the abortive Satellite Power Corp (1974-1976), which proposed using satellites to generate and transmit electrical power to the Earth.
Ehricke retired from Rockwell in July 1977 and established Space Global Company with himself as president. Space Global was, in essence, a vehicle to promote space exploration and to promulgate his vision of a future space civilization, a concept he originally called the "Extraterrestrial Imperative" but later referred to as the "Open World Synthesis." The basic concept was relatively straightforward: because Earth's resources, although great, are limited, they place a limit on mankind's development. The only way to escape that limit is to move beyond the Earth and exploit the resources available in space. It was an argument for space exploration and colonization that Ehricke developed during the 1950s and 1960s, and finally crystallized in a manuscript he co-authored with Elizabeth Miller. Doubleday planned to publish the book in 1971, but then cancelled the project. Ehricke managed to get facets of the idea published in a number of technical journals, most notably in a four-part article in the Journal of the British Interplanetary Society (1979-1981), and gave numerous lectures on the topic, but The Extraterrestrial Imperative never appeared in the general media. Described as a "warm, witty man" and "a popular lecturer," he kept up an active speaking career until his health began to fail in 1984. He died of complications from leukemia on 11 December 1984.
During his life Ehricke wrote over 200 scientific and technical papers, contributed to a number of dictionaries and encyclopedias, and authored or co-authored several books. His final book The Seventh Continent: Industrialization and Settlement of the Moon (published in German as Der Siebente Kontinent – Die Industri Alisierung und Besiedlung des Mondes (Müchen: Thiemig Verlag, 1984)) was being edited for English publication at the time of his death. He was awarded an Honorary Doctorate of Humane Letters by the National College of Education (note 6) (1961) and received numerous awards including the International Astronautical Federation's Guenther Loeser Medal (1956), the American Rocket Society's Astronautics Award (1957) and Edward J.

3. Operation Paperclip was a program by the United States Office of Strategic Services (OSS) to bring German scientists to the United States in the immediate aftermath of World War II. More than 1500 scientists and engineers and nearly 4000 members of their families had entered the US by the end of 1947.
4. Walter Robert Dornberger (1895-1980) was a German artillery officer and engineer. In 1942 he was placed in charge of coordinating V-1 and V-2 development at Peenemünde. Captured by the British in 1945, he participated in Britain's -- Operation Backfire -- before being brought to the United States as part of -- Operation Paperclip -- , working on guided missile development for the United States Air Force. Between 1950 and 1965 he worked for Bell, eventually becoming a Vice President of the company. According to some stories he was responsible for poaching several -- Paperclip -- scientists away from the Army's Huntsville team for USAF projects.

Series II, Personal Life
Series III, Miscellaneous Material
Charles Ingram Stanton was born on July 28, 1893, in Medford, Massachusetts. He graduated from high school in Revere, Massachusetts in 1911; and earned a Bachelor of Science degree from Tufts College in 1917. After graduation, he joined the United States Army and was assigned to the Signal Corps. Upon graduation from the Corps flight school, Stanton was promoted to the rank of 2nd Lieutenant. Although he served in the Air Service during World War I, he was never assigned overseas, but remained in the United States conducting research regarding radios and their effects in aircraft. In December of 1918, Stanton was formally discharged from the Army.
Prior to his military discharge, Stanton accepted a position with the United States Post Office Department of Aerial Mail, and began work as a test pilot. On September 15, 1920, Stanton was promoted to Superintendent of Operations, United States Air Mail Service. He later resigned from the Post Office and went to work for the National Aeronautic Association (NAA). His tenure there was terminated for unknown reasons in 1923; he then went to work for the U.S. Engineer Corp as a surveyman. From 1925 through 1926, he was employed as a civil engineer in Miami, Florida. On January 17, 1927 Stanton returned to government service as an airplane and engine inspector for the United States Department of Commerce. He was named the Chief of Airways Engineering Division, Civil Aeronautics Authority (CAA) on May 4, 1937. While working there, he obtained patent number 2,147,679 for an illuminating system for runways. On June 29, 1940 Stanton was named Assistant Administrator and Director of the Bureau of Federal Airways. During his tenure with the CAA, Stanton attended several conferences and important meetings for the establishment of international airways. Stanton was instrumental in establishing the Provisional International Civil Aviation Organization. In 1944 he received an honorary doctorate from Tufts College for his contribution to the field of civil aeronautics.
On March 8, 1948 Stanton retired from the United States Government and took a teaching position at the Technological Institute of Aeronautics of Brazil as Professor of Air Navigation, and Chief of Airway Division. Upon returning to the United States in 1952, Stanton went to work for Bell Telephone Laboratories. He returned to work for the CAA in 1957, where he remained until his retirement in 1962.
Charles Ingram Stanton's love of flying did not end with his work. He remained an active member in the OX-5 Club, the Society of Air Mail Pioneers, Society of Airway Pioneers, and the Washington Air Derby Association. In addition to flying clubs, Stanton was a member of the Delta Upsilon Fraternity. Charles Ingram Stanton passed away in 1986.

This collection consists of historical files on FI, its predecessors, and subsidiaries. The material consists primarily of historical/public relations material, including photographs and brochures, but also includes significant amounts of business records for FEAC, Kreider-Reisner, Hiller, Republic, Ranger, Stratos, and Swearingen. The collection also documents Fairchild's joint ventures with Fokker, Pilatus, and other aircraft manufacturers. The material also includes an extensive negative collection as well as film and videotape libraries.
Scope and Contents note:
Sherman Mills Fairchild (1896-1971) founded Fairchild Aerial Camera Corporation (FAEC) in 1920. FAEC was incorporated in New York State for the purpose of developing, manufacturing and selling aerial photographic equipment. It went through many changes over the course of its existence. By 1971, FAEC was called Fairchild Industries, Inc. and had become an enormous corporation that produced such famous and history making aircraft as the Model 24 and A-10 as well as acquired other aviation industry giants such as Republic Aviation and Hiller Aircraft Company.
The Fairchild Industries, Inc. Collection, accessions 1989-0060 and 1990-0047, was donated to the Archives Division of the National Air and Space Museum, Smithsonian Institution in 1989 and 1990. The collection consists of printed and photographic materials. The subject matter of the material has a wide scope that includes, but is not restricted to, the following subject areas: public relations, legal matters, production photography, aircraft drawings and manuals, company published materials such as brochures and press releases, and history files. This collection does not contain the engineering files or the complete photo holdings or corporate records of Fairchild Industries, Inc or any of its predecessors.
The collection was maintained for many years by Theron Rinehart, a Fairchild Industries employee. Due to the large size and lack original order, the Archives Division decided to create a database as well as a traditional finding aid for access to the collection. Access to the Fairchild Docs database is available from the Archives Division by appointment. Aircraft types and designations are listed in the database and finding aid as they are in The Smithsonian National Air and Space Museum Directory of Airplanes Their Designers and Manufacturers, edited by Dana Bell, 2002 (Greenhill Books: London). Folder titles are those that appeared on the original folders and dates are provided for those materials that had them. The material was rehoused by the Archives Division and is now in acid free folders and boxes. There are few instances of water damage; these materials are indicated in the finding aid and database.
This finding aid contains a corporate history and chronology of the companies owned by of Fairchild Industries, Inc and a list of the Fairchild, Hiller, Republic and Swearingen aircraft documented in this collection. The books, periodicals and artifacts that were part of this collection have been removed. This finding aid contains a list of these materials. Please ask for assistance in contacting the NASM Branch and Smithsonian Libraries and the NASM Aeronautics Division.
Sherman Mills Fairchild's personal papers, The Sherman Fairchild Papers, can be found in the Manuscript Division of the Library of Congress.
The following information was taken from The Smithsonian National Air and Space Museum Directory of Airplanes: Their Designers and Manufacturers, edited by Dana Bell, 2002 (Greenhill Books: London).
"In 1924, Sherman Fairchild established the Fairchild Aviation Corp as the parent company for his many aviation interests. In 1930, The Aviation Corp (AVCO) purchased Fairchild Aviation and its subsidiaries, initially operating the various companies under their original names. The following year, Sherman Fairchild repurchased Fairchild Aviation Corp and began repurchasing the subordinate companies. In a December 1936 reorganization, Fairchild Aviation Corp divested itself of all aircraft manufacturing interests, placing them under a new Fairchild Engine and Airplane Co.
The original aircraft manufacturing subsidiary of Fairchild Aviation Corp was Fairchild Airplane Manufacturing Co; it was created in 1924 to design and build aircraft as platforms for Fairchild's aerial survey cameras. Fairchild Airplane Manufacturing was one of the subsidiaries purchased by AVCO in 1930, but not one of the first companies repurchased by Sherman Fairchild. In 1931 AVCO combined the aircraft company with Fairchild Engine Co, forming American Airplane and Engine Corp. Fairchild Aviation Corp bought American Airplane and Engine in 1934, renaming the company the Fairchild Aircraft Manufacturing and Engine Co.
In the 1936 reorganization that divided Fairchild Aviation Corp assets, Fairchild Aircraft Manufacturing and Engine Co became Fairchild Engine and Airplane Co and took charge of all Fairchild aircraft and engine holdings. Fairchild Engine and Airplane Co became Fairchild Engine and Airplane Corp in 1950 and Fairchild Stratos Corp in 1961. With the 1964 purchase of Hiller Aircraft Corp, Fairchild Stratos was renamed Fairchild Hiller Corp, then, again, renamed Fairchild Industries after the separation of all Hiller interests in 1973. Although Fairchild Industries closed and sold its military and commercial aircraft manufacturing divisions in 1987, "Fairchild" aircraft continued to be produced through the Swearingen Metro and Fairchild Dornier lines (see below).
Fairchild created, purchased, and merged with several companies during its history. The following are the most important subsidiaries:
Fairchild Aircraft Ltd was created in 1929 as Fairchild Aviation Corp's Canadian subsidiary. The company ended all aircraft production in 1948.
The Kreider Reisner Aircraft Co Inc was formed in 1927. Kreider Reisner became a wholly-owned division of (first) the Fairchild Airplane Manufacturing Co in 1929, (second) AVCO's American Airplane and Engine Corp (which renamed KR aircraft "Pilgrims") in 1931, and (third) Fairchild Aircraft Manufacturing and Engine Co in 1934. Kreider-Reisner was renamed the Fairchild Aircraft Corp in 1935, becoming Fairchild Engine and Airplane Co's principle US aircraft manufacturing subsidiary. Fairchild Aircraft Corp was renamed the Fairchild Aircraft Division in 1939, the Fairchild Aircraft and Missiles Division in 1961, the Fairchild Stratos Aircraft and Missiles Division in 1961, the Aircraft-Missiles Division in 1965, and the Aircraft Division in 1967. With a growing number of aircraft subsidiaries reporting to Fairchild Industries, the Aircraft Division was broken up in a corporate reorganization of the 1970s. While the Kreider Reisner Midget is listed under Kreider Reisner, all Kreider Reisner Challenger series aircraft (designated "KR" biplanes by Fairchild) appear under Fairchild.
In 1936 Fairchild Engine and Airplane Co founded the subsidiary Duromold Aircraft Corp to better account for time spent developing the Duromold wood/resin bonding process and the Model 46 aircraft. In 1938, the majority interest in Duromold was bought by a group of investors (including process inventor Col. Virginius E. Clark), who formed the Clark Aircraft Corp. Fairchild kept a minority interest in Clark, retaining Duromold as a holding company. In September 1938, Fairchild renamed its Duromold division Fairchild Airplane Investment Corp, and Clark created a subsidiary called Duramold Aircraft Corp (note the spelling change). In 1938 Duramold was renamed Molded Aircraft Corp. In 1939, Fairchild Engine and Airplane Corp bought back a controlling interest in Clark and renamed Molded Aircraft Duramold Aircraft Manufacturing Corp. The Duramold and Clark companies disappeared during one of Fairchild's World War II reorganizations.
In 1952 Fairchild licensed the rights to Dutch Fokker's F.27 medium-range airliner. In 1953, the USAF transferred production contracts for the Chase Aircraft Co, Inc C 123 to Fairchild. The Chase-built XC 123 and XC 123A appear under Chase, while Fairchild's C-123 production is listed under Fairchild.
In 1954, the American Helicopter Co, Inc (founded 1947) became the Helicopter Division of Fairchild Engine and Airplane Corp. The division closed by the end of decade.
In 1964, Fairchild Stratos purchased Hiller Aircraft Corp, and both companies were renamed: Hiller Aircraft Co Inc become a subsidiary of Fairchild Hiller Corp. In the 1973 reorganization of Fairchild Hiller into Fairchild Industries, Hiller helicopter interests passed to an independent Hiller Aviation Inc….
In 1965, the Republic Aviation Corp became Republic Aviation Division (also known as Fairchild Republic) of Fairchild Hiller Corp. In 1987, Republic was shut down when Fairchild Industries ceased building commercial and military aircraft.
Swearingen Aircraft formed in the late 1950s, modifying Beech aircraft for executive transport. In 1965 the company produced its first new design, the Merlin. In 1970 Swearingen began development of the Metro, a joint venture to be marketed by Fairchild Hiller Corp. As a subsidiary of Fairchild Industries, Swearingen became Swearingen Aviation Corp, in 1971, Fairchild Swearingen in 1981, and Fairchild Aircraft Corp in September 1982. When Fairchild Industries closed its aircraft design and production facilities in 1987, Fairchild Aircraft Corp was sold to GMF Investments, Inc; GMF continued to operate the company under the Fairchild name. In 1990, Fairchild Aircraft filed for Chapter 11 protection and was purchased by Fairchild Acquisition Inc as Fairchild Aircraft Inc. Fairchild Aircraft delivered its last aircraft in 2001. Most Swearingen designs are filed under Swearingen; the Metro and Expediter can be found under Fairchild.
In 1996, Fairchild Acquisition became Fairchild Aerospace. While continuing to operate Fairchild Aircraft, the company also purchased 80% of the stock of Germany's Dornier Luftfahrt GmbH (with the remaining 20% of shares held by Daimler Benz Aerospace). Dornier's aircraft manufacturing operations were taken over by Fairchild Dornier Luftfahrt Beteiligungs GmbH. In 2000, Fairchild Aerospace was renamed Fairchild Dornier Aerospace, with corporate headquarters moved to Germany. Dornier designs predating Fairchild's takeover are listed under Dornier. Subsequent designs are found under Fairchild Dornier."

The collection forms a documentary record of over half a century of the history of radio, with the greatest emphasis on the period 1900-1935. The collection includes materials that span the entire history of the growth of the radio industry. It is useful for those historians and other researchers interested in technological development, economic history, and the impact of applications of technology on American life.
Scope and Contents:
The materials accumulated in this collection represent the overriding collecting passion of one individual, George H. Clark. The collection forms a documentary record of over half a century of the history of radio, with the greatest emphasis on the period 1900-1935.
The collection includes materials that span the entire history of the growth of the radio industry. It is useful for those historians and other researchers interested in technological development, economic history, and the impact of applications of technology on American life.
In particular, the collection is rich in biographical information on the men who developed the technical aspects of radio and the industry; information on the inception, growth, and activities of radio companies, most notably the National Electric Signaling Company and RCA; and in photographs of all aspects of Radioana.
While most materials document technical aspects of radio, there is much information (e.g. Series 109, 134) on broadcasting and on the early history of television.
The collection, housed in over 700 boxes (about 276 linear feet), was organized into 259 numbered "classes" or series by Clark. Sixty series numbers were never used or were eliminated by Clark and combined with other series. The unused numbers are scattered throughout the filing system. The collection also includes material from series that were eliminated. These materials were never reclassified and are included as an unprocessed series at the end of the series descriptions. The collection also contains material that was never assigned a "class" designation by Clark (Lettered Series: D, E, F, G, H).
The arrangement of the collection is Clark's own; his adaptation of the Navy filing system he helped devise in 1915. Clark periodically revised the filing system and reclassified items within it.
Clark assigned class numbers to types of equipment (e.g. broadcast receivers), systems (impulse-excited transmitters and systems), scientific theories (circuit theory), and topics (company history, biography). Box 1 contains descriptions of the classification system.
When Clark classified an item and filed it he also assigned a serial number. This classification begins with 1 (or 1A) for the first item in the class and continues with successive numbers as items were added. As a consequence, the order of individual items within a series reflects the order in which Clark filed them, not any logical relationship between the items. Clark created cross references for items dealing with more than one subject by making notations on blank sheets of paper placed in related series.
Clark made cross references between series when there was no logical relationship between them; that is, when a person using the collection would not normally look in the series. For example no cross reference would be made of an engineer from series 87 (portraits) to series 4 (biography), but one would be made from series 87 to series 142 (history of television) if the item showed the engineer, say, working on a television installation.
Clark created the insignia "SRM" as the sign on the bottom of all sheets of paper numbered by him for binding. SRM stood for Smithsonian Radio Museum. This replaced the earlier though not greatly used sign "CGM." For a time about 1930, the class number on each sheet was preceded by these: "C.G.M.", for Clark, Martin, and Goldsmith, the earliest contributors to what would become the Clark Radioana Collection. After about 1933-34 Clark used C.W.C. for Clark Wireless Collection.
There are many photographs located in most series throughout the collection. But there are also three exclusive photographic series. Lettered series A, B, C. See index; and also series descriptions under lettered series.
The collection is divided into 223 series.

Biographical / Historical:
George Howard Clark, born February 15, 1881, at Alberton, Prince Edward Island, Canada, emigrated to the United States at the age of fourteen. He worked as a railroad telegraph operator for the Boston and Maine Railroad during high school and college. In his unpublished autobiography he wrote:
In 1888, when I was a lad of seven, I suddenly blossomed out as a scrapbook addict, and for years I gave up boyhood games for the pleasure of sitting in a lonely attic and 'pasting up' my books ... By 1897, in high school, I graduated to beautiful pictures, and made many large size scrapbooks ... Around that time, too, I became infatuated with things electrical, and spent many evenings copying in pen and ink the various electrical text books in the Everett, Mass., Public Library. Clark began collecting material pertaining to wireless or radio in 1902. In 1903 he graduated from the Massachusetts Institute of Technology with a Bachelor of Science degree in Electrical Engineering. During his last year of college he specialized in radio work under the instruction of Professor John Stone Stone and after graduation went to work for Stone's radio company, the Stone Telegraph and Telephone Company, of Boston.
In 1908 Clark took a competitive examination open to all wireless engineers in the United States and entered the civilian service of the Navy. He was stationed at the Washington Navy Yard, with special additional duty at the Navy's Bureau of Steam Engineering and at the National Bureau of Standards.
In 1915 Clark helped devise a classification system for Navy equipment, assigning a code number to each item. This system of classification for blueprints, photographs, reports, and general data, was prepared by Arthur Trogner, Guy Hill, and Clark, all civilian radio experts with the US Navy Department in Washington. In 1918 Clark adopted the 1915 Navy classification system for organizing the radio data he was accumulating. Clark created the term "Radioana" at this time. He began spending his evenings and weekends pasting up his collection and numbering pages. At this time he bound the accumulated material. It totaled 100 volumes.
In July 1919, after resigning from the Navy, Clark joined the engineering staff of the Marconi Telegraph Company of America, which became part of the Radio Corporation of America (RCA) later the same year. His first work was at Belmar and Lakewood, New Jersey, assisting the chief engineer, Roy A. Weagant, in his development of circuits to reduce the interference caused by static (static reduction). Clark and his wife were assigned to the unheated Engineer's Cottage. His wife decided not to stay and left for Florida. Clark moved his trunks of wireless material to the heated RCA hotel at Belmar and spent most of the winter "pasting." As Clark mentions, "From that time on I was wedded to scraps."
After a year of work in New Jersey, Clark was assigned to the sales department in New York, where he devised the "type number system" used by RCA. This type number system, for example, gave the designation UV 201 to the company's first amplifier tube.
From 1922 to 1934 Clark was in charge of RCA's newly created Show Division, which held exhibits of new and old radio apparatus at state fairs, department stores, and radio shows. About 1928 Clark started an antique radio apparatus museum for RCA. RCA's board of directors announced:
Recognizing the importance of providing a Museum for the Radio Art to house the rapidly disappearing relics of earlier days, and the desirability of collecting for it without further delay examples of apparatus in use since the inception of radio, the Board of Directors of RCA has made an initial appropriation of $100,000, as the nucleus of a fund for the establishment of a National Radio Museum. A plan for ultimately placing the museum under the wing of the Smithsonian Institution was coupled with the goal of the Institution's gathering the largest possible library of wireless data.
Around 1933 the RCA traveling exhibition program ended and Clark started classifying his collected "radioana" material. The objects of the museum were eventually turned over for exhibit purposes to the Rosenwald Museum in Chicago and the Henry Ford Museum in Dearborn, Michigan, when space was not forthcoming at the Smithsonian. A list of objects sent to the two museums (with tag and case numbers) is in Series 1, Box A. The "radioana" collection remained under Clark's care during the 1930s, and became of increasing use to RCA. Clark continued to add to the material.
Between 1934 and 1942 Clark was in court many times regarding patent infringements. Clark's wireless data was useful and he testified frequently, for example, in RCA's suit against the United States in the Court of Claims over the Marconi tuning patents and in the Westinghouse Company's suit against the United States over the heterodyne. Patent specifications and material regarding these and other radio industry suits are found throughout this collection.
In 1946 RCA retired George Clark and denied him space to house his "radioana" collection. Clark wished to remain in New York and house the collection somewhere in the city where it would be open at all times to the public and where it would be maintained. He hoped to continue cataloguing the collection and writing books from its information. He wanted to keep the collection under his control for as long as he was capable of using it.
George H. Clark died in 1956 and his collection was subsequently given to the Massachusetts Institute of Technology. In 1959 the collection was given to the Smithsonian's new Museum of History and Technology, where space was available to house it. The collection remained in the Division of Electricity until the spring of 1983 when it was transferred to the Archives Center.
Brief Company Histories From The Radio Industry, 1900-1930s:
At the end of the nineteenth century, when Guglielmo Marconi began his first wireless company, Western Union, Postal Telegraph, and the American Telephone and Telegraph Company (AT&T) were the major enterprises in electrical communications. General Electric, Western Electric, and Westinghouse were the major producers of electrical equipment. All these earlier developments set the stage for the expansion of the radio industry.
General Electric, which dominated the lighting industry, was formed in 1892 as a merger of the Edison and Thomson-Houston companies. It was active in building central power station equipment; controlled nearly all the important early patents in electric railways; took a leading part in the introduction of trolley systems; and was the principal supplier of electric motors. Westinghouse promoted the alternating current system and installed the first AC central station in Buffalo, NY, during the winter of 1866-1867. After years of patent litigation, in 1896 GE and Westinghouse agreed to share their patents on electrical apparatus.
American Bell Telephone Company purchased Western Electric in 1881. Western Electric had a strong patent position in telephone equipment and in industrial power apparatus, such as arc lamps, generators, motors, and switchboard equipment.
Until RCA was formed in 1919, these established electrical companies played no active part in the early development of the American radio industry. They were in difficult financial positions, reorganizing, or concentrating their efforts and resources on improving their existing products.
The revolution in "wireless" technology, which began in earnest after 1900, centered in New York City, home of the Lee de Forest and American Marconi companies, and in Boston, headquarters of John Stone Stone and Reginald Fessenden.
Information in this section was compiled from the Clark Collection; the Invention and Innovation in the Radio Industry by W. Rupert Maclaurin, Macmillan Company, New York, 1949; and Radio Pioneers, Institute of Radio Engineers, Commemorating the Radio Pioneers Dinner, Hotel Commodore, New York, NY, November 8, 1945.
The De Forest Companies
Lee De Forest (1873-1961), inventor of the three-element vacuum tube or triode (1906) and the feedback circuit, was one of the first Americans to write a doctoral thesis on wireless telegraphy: "The Reflection of Short Hertzian Waves from the Ends of Parallel Wires," Yale University, 1899. The grid-controlled tube or audion of De Forest was first a radio detector, 1906-1907; in 1912 was adapted to an amplifier; and later to an oscillator. When it was perfected as a high vacuum tube, it became the great electronic instrument of electrical communications.
De Forest began work in the Dynamo Department at the Western Electric Company in 1899. Six months later he was promoted to the telephone laboratory. In 1900 De Forest went to work for the American Wireless Telegraph Company where he was able to carry out work on his "responder." However, after three months when De Forest refused to turn over the responder to the company, he was fired.
In the following year De Forest had a number of jobs, was active as an inventor, and created numerous firms to manufacture his inventions. In 1901 De Forest joined with Ed Smythe, a former Western Electric colleague and a collaborator in his research, to found the firm of De Forest, Smythe, and Freeman. Between 1902 and 1906 De Forest took out thirty-four patents on all phases of wireless telegraphy. The responder that he had been working on for so long never proved satisfactory.
The numerous De Forest companies, reflected his many interests and his inability to carry one project through to a conclusion. Unlike Marconi, but similar to Fessenden, De Forest had great inventive skill which resulted in a great number of companies; but none lasted long. The original partnership of 1901 led to the Wireless Telegraph Co. of America (1901), the De Forest Wireless Telegraph Company (Maine) (1902), and the American De Forest Wireless Telegraph Company (1903), to name a few.
The American De Forest Wireless Telegraph Company was incorporated after De Forest met a stock promoter, Abraham White. While many stations were built by this company, many never sent a message due to static interference. In 1907 two speculators from Denver with large holdings of company stock put the company out of business. The assets were sold to a new company that these speculators organized, the United Wireless Telephone Company. De Forest was forced to resign. He took the triode patents with him.
De Forest joined with one of White's stock salesmen, James Dunlop Smith, and together with De Forest's patent attorney, Samuel E. Darby, they formed a new corporation, the De Forest Radio Telephone Company in 1907. This company set out to develop wireless communication by means of the radio telephone.
In January 1910 De Forest staged the first opera broadcast, with Enrico Caruso singing. The Radio Telephone Company went bankrupt in 1911 following an aborted merger with North American Wireless Corporation. In 1913 he reorganized the company as the Radio Telephone and Telegraph Company and began producing the triode.
The Marconi Company brought a patent suit, claiming the triode infringed on the Fleming valve to which it had rights. In 1916 the court decided that Marconi had infringed the three element De Forest patent and that De Forest had infringed the two element Fleming valve. The result was that neither company could manufacture the triode.
In 1920 RCA acquired the De Forest triode rights through cross-licensing agreements with AT&T which had recently purchased the rights to it. De Forest's company was no match for GE, Westinghouse, and RCA. The De Forest Radio Company (1923) went bankrupt in 1928, was reorganized in 1930, and went into receivership in 1933. RCA eventually purchased its assets.
Guglielmo Marconi (1874-1937) came from a wealthy and well connected Italian family. He was able to spend his time developing his inventions and following his own course of action. Marconi spent his entire life developing wireless communication into a "practical" reality. In 1905 Marconi invented a directional antenna. In 1909 he shared with Karl Ferdinand Braun the Nobel prize in physics. And in 1912 he invented the time spark system for the generation of continuous waves. The principal patents in his name were improved types of vertical antennas; improved coherer; magnetic detector for the detection of wireless signals; and improvements on methods of selective tuning. Two other inventions of great importance to the Marconi companies' patent structure were the Oliver Lodge tuning patent and the Ambrose Fleming valve.
In 1895 Marconi made the first successful transmission of long wave signals. The following year he met William Preece, engineer-in-chief of the British Post Office, who was interested in inductive wireless telegraphy. This meeting led to the formation in 1897 of the Marconi Wireless Telegraph Company Ltd. In 1898 he transmitted signals across the English Channel. In 1899 an American subsidiary was formed. The various Marconi companies were the dominant enterprises in both British and American wireless until 1919 when RCA was formed.
From a business standpoint, wireless did not become profitable until long distance communications were accomplished. On December 12, 1901 in St. John's, Newfoundland, Marconi received a telegraph signal in the form of repetitions of the Morse telegraphic letter "S" transmitted from the Marconi station at Poldhu, Cornwall, England. This success, however, was met by opposition from vested interests, particularly the Anglo-American Telegraph Company whose cables terminated in Newfoundland.
So as not to restrict his company's future to one front alone, Marconi decided to exploit the field of communication with ships at sea. In order to control this field he decided in 1900 to lease his apparatus rather than sell it outright. This strategy did not work. Competition developed in Germany (Telefunken Corporation) and the United States (American De Forest and its successor, United Wireless) and Marconi was forced to sell rather than lease apparatus to the navies of various countries. He nevertheless retained numerous restrictions. This led to further friction. At the height of this debacle English stations worldwide refused to communicate with ships without Marconi equipment. This absurd and dangerous situation had to change and coastal stations opened up to all senders in 1908.
Marconi's system was based on spark technology. He saw no need for voice transmission. He felt the Morse code adequate for communication between ships and across oceans. He, along with most others, did not foresee the development of the radio and the broadcasting industry. He was a pragmatist and uninterested in scientific inquiry in a field where commercial viability was unknown.
For these reasons Marconi left the early experimentation with the radio telephone to others, particularly Lee De Forest and Reginald Fessenden.
National Electric Signaling Company
Canadian-born Reginald Fessenden (1866-1932), one of the principal early radio inventors and the first important inventor to experiment with wireless, left the University of Pittsburgh in 1900 to work for the U.S. Weather Bureau. There he invented the liquid barretter, an early radio receiver, and attempted to work out a means for wireless transmission of weather forecasts. After a squabble over patent rights, Fessenden resigned in 1902.
The National Electric Signaling Company (NESCO), primarily intended to support Fessenden's work on wireless, telegraphy, and telephony, was formed by Fessenden and two Pittsburgh capitalists, Hay Walker, Jr. and Thomas H. Given. It began as an inventor's laboratory and never proved successful as a business venture.
Fessenden recognized that a continuous wave transmission was required for speech and he continued the work of Nikola Tesla, John Stone Stone, and Elihu Thomson on this subject. Fessenden felt he could also transmit and receive Morse code better by the continuous wave method than with a spark-apparatus as Marconi was using.
In 1903 Fessenden's first high-frequency alternator needed for continuous wave transmission was built to his specifications by Charles Steinmetz of GE. In 1906 Fessenden obtained a second alternator of greater power from GE and on Christmas Eve broadcast a program of speech and music. The work on this alternator was given to Ernst F. W. Alexanderson. It took years for Alexanderson to develop an alternator capable of transmitting regular voice transmissions over the Atlantic. But by 1916 the Fessenden-Alexanderson alternator was more reliable for transatlantic communication than the spark apparatus.
Fessenden also worked on continuous-wave reception. This work arose out of his desire for a more effective type of receiver than the coherer, a delicate device that was limited by its sensitivity on a rolling ship at sea. In 1903 he developed a new receiving mechanism - the electrolytic detector.
As his work progressed Fessenden evolved the heterodyne system. However, due to faulty construction and the fact that it was ahead of its time, heterodyne reception was not fully appreciated until the oscillating triode was devised, thus allowing a practical means of generating the local frequency.
Between 1905 and 1913 Fessenden developed a completely self-sustaining wireless system. However, constant quarrels between Fessenden, Walker, and Given culminated in Fessenden's forming the Fessenden Wireless Company of Canada. He felt a Canadian company could better compete with British Marconi. As a result, his backers dismissed Fessenden from NESCO in January of 1911. Fessenden brought suit, won, and was awarded damages. To conserve assets pending appeal, NESCO went into receivership in 1912, and Samuel Kintner was appointed general manager of the company.
In 1917 Given and Walker formed International Signal Company (ISC) and transferred NESCO's patent assets to the new company. Westinghouse obtained majority control of ISC through the purchase of $2,500,000 worth of stock. The company was then reincorporated as The International Radio Telegraph Company. The Westinghouse-RCA agreements were signed in 1921 and International's assets were transferred to RCA.
The development of the radio industry accelerated after 1912. This was due to several factors, the most important of which was the passage of legislation by the US government requiring ships at sea to carry wireless. This created a market incentive and spurred the growth of the industry. Also, with the outbreak of World War I, the larger electrical companies turned their manufacturing output to radio apparatus, supporting the war effort. Three firms were prominent in this industrial endeavor: AT&T, GE, and Westinghouse.
AT&T's early contributions to this effort centered on their improvements of De Forest's triode, particularly in the evolution of circuits, the redesign of the mechanical structure, and an increase in the plate design. The importation of the Gaede molecular pump from Germany created a very high vacuum. The resulting high-vacuum tube brought the practical aspects of the wireless telephone closer to reality. By August 1915 speech had been sent by land wire to Arlington, Va., automatically picked up there via a newly developed vacuum-tube transmitter, and subsequently received at Darien, Canal Zone. By 1920 AT&T had purchased the rights to the De Forest triode and feedback circuit, and had placed itself in a strong position in the evolution of radio technology.
GE centered its efforts on the alternator, assigning Ernst F. W. Alexanderson to its design, and on further development of vacuum tube equipment for continuous wave telegraph transmission. By 1915 Alexanderson, Irving Langmuir, William D. Coolidge, and others had developed a complete system of continuous wave transmission and reception for GE.
As can be seen, both AT&T and GE were diverting major time and expenditures on vacuum tube research. This inevitably led to patent interferences and consequently, to cross-licensing arrangements.
Westinghouse was not in the strategic position of GE and AT&T. Nevertheless, during the war it did manufacture large quantities of radio apparatus, motors, generators, and rectifiers for the European and American governments. Postwar moves led Westinghouse into full partnership with the other two companies.
By the end of the war, all three companies had committed significant resources to wireless. They were hampered internationally, however, by the Marconi Company's dominant status, and in the United States they were blocked by opposing interests with control of key patents.
The US government also was concerned with this lack of solidarity in the wireless industry and over the British domination of the field worldwide. This impasse set a fascinating and complicated stage for the formation of the RCA.
Owen D. Young, legal counselor for GE, was instrumental in breaking the impasse. Through an innovative and far-reaching organizational consolidation, Young was able to persuade British Marconi that persistence in monopoly was a fruitless exercise, because of the strong US government feelings. Marconi, realizing the harm of a potential American boycott, finally agreed to terms. GE purchased the controlling interest in American Marconi, and RCA was formed. Young was made chairman of the board of RCA, while Edwin J. Nally and David Sarnoff of the old American Marconi were appointed president and commercial manager respectively.
On July 1, 1920, RCA signed a cross-licensing agreement with AT&T. The telephone company purchased one half million shares of RCA common and preferred stock for several considerations -- the most important being that all current and future radio patents of the two companies were available to each other royalty-free for ten years. Many provisions of these agreements were ambiguous and led to later squabbles between the RCA partners.
In May 1920 Westinghouse, which had an efficient radio manufacturing organization, formed an alliance with the International Radio and Telegraph Company (NESCO's successor). Westinghouse's part ownership gave them control of Fessenden's patents, particularly continuous-wave transmission and heterodyne transmission. Westinghouse also wisely purchased in October of 1920 Armstrong's patents on the regenerative and superheterodyne circuits -- which also included some of Columbia University professor Michael Pupin's patents. This placed Westinghouse in a strong bargaining position vis-à-vis RCA and in their new consolidated corporation. Westinghouse joined the growing group of radio companies on June 30, 1921. With these mergers, RCA agreed to purchase forty percent of its radio apparatus from Westinghouse and sixty percent from GE.
Through these and other legal arrangements, RCA obtained the rights to over 2,000 patents. These amounted to practically all the patents of importance in the radio science of that day. As a result, other firms in the radio industry, for example, the United Fruit Company and the Wireless Specialty Apparatus Company, entered into cross-licensing arrangements with RCA.
RCA also made arrangements internationally with the three dominant companies in radio communication in their respective countries. British Marconi, Compagnie Generale de Telegraphie sans fil, and Telefunken. Each corporation was given exclusive rights to use the other companies' patents within their own territories.
The rise of amateur radio in the 1920s and, to a greater extent, the demand for new products by the general public contributed to the rise of the broadcasting industry. This put a strain on the earlier agreements between the major radio corporations and between 1921 and 1928 there was a struggle over patents for control of the evolving medium.
An initial attempt by AT&T to control the broadcasting industry -- using its earlier cross-licensing agreements to manufacture radio telephone transmitting equipment -- began with AT&T's disposal of RCA stock holdings in 1922-1923. It ended in 1926 with a new cross-licensing agreement which gave AT&T exclusive patent rights in the field of public service telephony and gave GE, RCA, and Westinghouse exclusive patent rights in the areas covered by wireless telegraphy, entertainment broadcasting, and the manufacture of radio sets and receiving tubes for public sale.
In 1926 after the agreements were finalized, RCA, GE, and Westinghouse joined forces and established the National Broadcasting Company (NBC). Fifty percent of the stock went to RCA, thirty percent to GE, and twenty percent to Westinghouse. The new company was divided into three divisions: the Red, Blue, and Pacific Networks. Independent, competing networks soon emerged. William S. Paley and his family formed the Columbia Broadcasting System (CBS) in 1927. The Mutual Broadcasting System was formed in 1934.
By 1928 RCA had strong patent positions in all major areas of the radio industry, including the research, development and manufacture of vacuum tubes and speakers. Most small companies entering the industry in the 1920s produced their products based on prior research by others and on expired patents. An RCA license, therefore, was essential for the manufacture of any modern radio set or vacuum tube.
In the late 1920s new developments in the reproduction of sound, produced significant changes in the phonograph industry. Among those new developments were the introduction of the electronic record, and the marketing of the Radiola 104 Loudspeaker in 1926. In 1929 RCA purchased the Victor Talking Machine Company. This changed not only the quality but the sales of the phonograph and the phonograph record. A new entertainment industry was born and an ever-expanding market for consumer products was created with cultural implications that continue today.
German industrialists were eager to break the Marconi Company's monopoly. Although Marconi had patents on his inventions in Germany, the Germans developed a rival system through the Telefunken Corporation, incorporated in 1903, based on the inventions of Professor Ferdinand Braun, Dr. Rudolf Slaby, and Count George von Arco.
Before 1903 the Braun-Siemens and Halske system had been developed by Gesellschaft fur Drahtlose Telegraphie (GFDT). The Slaby-Arco system had been developed by Allgemeine Electrizitats-Gesellschaft. After litigation over patents, the German court handed down a decision in favor of the GFDT. The Kaiser, with national interests in mind, ordered that the rivalry cease. The two systems were amalgamated under GFDT, and became known as the Telefunken.
Chronology of Some Significant Events In The History of The Radio Industry
1895 -- Marconi experiments with Hertz's oscillator and Branley's coherer.
1897 -- In March Marconi demonstrates his wireless system on Salisbury Plain, near London, and files a complete patent specification. In May trials of Marconi's system are made over water between Lavernock and Flatholm, a distance of three miles. On May 13, communication is established between Lavernock Point and Brean Down, a distance of eight miles. German scientist Professor Slaby is present. The first Marconi station is erected at the Needles, Isle of Wight. A distance of fourteen and one-half miles is bridged by wireless. In December the Marconi station at the Needles communicates with a ship eighteen miles at sea.
1898 -- In England Oliver Lodge files a complete specification covering inventions in wireless telegraphy.
1899 -- The New York Herald uses Marconi's wireless telegraphy to report the progress of the International Yacht races between the Columbia and the Shamrock off New York harbor in September. US. Navy vessels make trials of Marconi's wireless telegraph system. The cruiser New York and the battleship Massachusetts are equipped with apparatus. Fessenden develops improvements in methods of wireless telegraph signaling.
1900 -- The Marconi International Marine Communication Company is organized on April 25th in London. Reginald Aubrey Fessenden begins work at the United States Weather Bureau. Over the next two years he invents the liquid barretter, an improved radio receiver.
1901 -- In February on board the SS Philadelphia, Marconi receives wireless signals over a distance of 1,551 miles. In March Marconi wireless telegraph service begins between islands of the Hawaiian group. On December 12, Marconi receives transatlantic signal at St. John's, Newfoundland from Poldhu, Cornwall, England. The Canadian government orders two Marconi telegraph sets for use at coastal points along the Strait of Belle Isle.
1901 -- Fessenden procures US patent no. 706737 for a system of radio signaling employing long waves (low frequency).

1911 -- A radio section is organized by the US Department of Commerce to enforce the provisions of national radio legislation. Marconi Wireless Telegraph Company acquires the Lodge-Muirhead patents.
1912 -- Rotary gap is used with Fessenden 100 kW 500 cycle spark set at NAA, the Navy's first high-power station at Arlington, Virginia. Marconi Wireless of America acquires property of the United Wireless Telegraph Company. British Marconi secures the important radio patents of Bellini and Tosi, Italian inventors. Wreck of the SS Titanic on April 15th. The act of 1910 is extended on July 23 to cover cargo vessels. requires an auxiliary source of power on ships and two or more skilled radio apparatus operators on certain types of passenger ships. On August 13, an act provides for licensing radio operators and transmitting stations.
1912-1913 -- High vacuum amplifying tubes (an improvement on De Forest's), using the findings of pure science, are produced almost simultaneously in two great industrial laboratories, by Dr. H. D. Arnold of AT&T and Irving Langmuir of GE.
1915 -- De Forest Ultra-audion three-step (cascade) audio amplifier is announced and introduced into practice.
1916 -- GE and the Western Electric Company develop the first experimental vacuum tube radiotelephone systems for the Navy.
1917-1918 -- First production of vacuum tubes in quantity, both coated filament and tungsten filament types, by Western Electric Company and GE.
1918 -- Lloyd Espenschied procures US patent number 1,256,889 for the invention of a duplex radio telegraph system. (See Lloyd Espenschied Papers, Archives Center, NMAH, Collection #13.) The House of Representatives passes a resolution on July 5, authorizing the President to take over management of telegraph and telephone systems due to war conditions.
1919 -- Bills are introduced in Congress for permanent government control of radio stations. The widespread resentment of amateurs has more to do with the defeat of these bills than the objections of commercial companies. Roy Alexander Weagant, New York, reports having developed means of reducing disturbances to radio reception caused by atmospherics or static. This is the first successful static-reducing system. GE purchases the holdings of the British Marconi Company in the Marconi Wireless Telegraph Company of America, the name of the latter company being changed to Radio Corporation of America (RCA) in October. Edward J. Nally is elected president of the new company.
1920 -- E. F. W. Alexanderson is appointed Chief Engineer of RCA. RCA begins the installation of 200-kW Alexanderson alternators at Bolinas, California, and Marion, Massachusetts. The Tropical Radio Telegraph Company, a subsidiary of the United Fruit Company, New York, operates ten long-distance radio stations at points in Central and South Americirca RCA purchases 6,000 acres at Rocky Point, Long Island, New York, and begins erection of a Radio Central station, comprising a number of operating units for communication with European stations and stations in South Americirca On May 15, RCA inaugurates radio telegraph services between installations at Chatham and Marion, Massachusetts, and stations at Stavanger and Jaerobe, Norway. Westinghouse Company's radio station KDKA, Pittsburgh, Pennsylvania, broadcasts returns of the national elections, November 2. Development, design, and manufacture by GE of the early receiving and transmitting tubes made available to the public by RCA (UV-200,201,202). Radio telegraph stations and properties taken over by the government under war time powers are returned to their owners at midnight, February 29. The government calls for bids for the sale of large quantities of surplus radio and telegraph and telephone apparatus purchased for war needs and not used.
1921 -- RCA develops Vacuum tubes UV-200(detector) and UV-201(amplifier) -- both triodes with brass shells known as the UV base, and incorporating a filament that required 1 ampere at 5 volts for operation -- for storage battery operation; and at the same time also released to the public the WD-11 for dry cell operation, which employed an oxide-coated tungsten filament. RCA station at Rocky Point, Long Island, opens on November 5. WJZ station established by the Westinghouse Company in Newark, NJ. RCA broadcast station at Roselle Park, NJ (WDY) opens on December 15. It continues operation until February 15, 1922, when its operation is transferred to WJZ, Newark, previously owned by Westinghouse. RCA installs 200-kW alternator at Tuckerton, NJ.
1922 -- First use of tube transmitters by RCA for service from the United States to England and Germany. RCA begins substitution of tube transmitters on ships to replace spark sets. RCA begins replacement of crystal receivers by tube receivers on ships.
1923 -- Broadcast stations WJZ and WJY opened in New York in May by RCA. WRC opens in Washington on August 1. The UV-201A, receiving tubes developed by GE and consuming only 1/4 of an ampere are introduced by RCA. Tungsten filaments coated and impregnated with thorium were employed.
