Historical note:
An historic event in aviation occurred on June 26, 1929 when two major aircraft companies: the Curtiss Aeroplane and Motor Company merged with the Wright Aeronautical Corporation to form the Curtiss-Wright Corporation. After this merger, the former Wright organization took over all of the engine and propeller manufacture while Curtiss concentrated on airplanes. This merger was completed by organizing two major divisions under their original names, but under the direction of a corporate headquarters located in New York City. However, there was a recognized separation of spirit as well as specialized facilities that was never completely resolved in succeeding years. The election of former Wright personnel to key corporate positions soon led to Wright becoming the dominant division. At the height of the Lindbergh Boom during the 1920s and 1930s, the Curtiss-Wright Corporation was made up of the following identified organizations: The Curtiss Aeroplane & Motor Company; The Curtiss-Caproni Corporation; The Curtiss-Robertson Airplane Manufacturing Company; The Keystone Aircraft Corporation; The Moth Aircraft Corporation; The Travel Air Manufacturing Company; The Wright Aeronautical Corporation; Curtiss-Wright Flying Service; The Curtiss-Wright Sales
Corporation; The Curtiss-Wright Export Corporation. Curtiss-Wright was quickly becoming the 'General Motors of the Air' until the great depression in October 1929. Sales dropped and Curtiss-Wright was forced to close certain satellite plants and transfer some of their product lines to the St. Louis facility. It looked like even the Buffalo plants would also have to close when Curtiss-Wright received an order from Colombia, South America for Hawks and Falcons. This was the largest military order to Curtiss since the war. The Colombia sale saved the Curtiss-Wright organization at this low point in its history. This order kept the production lines going until new military and civil markets began to open up as the depression waned and the build-up for World War II began. During the U.S. military build-up prior to the attack on Pearl Harbor, all existing Curtiss-Wright plants were expanded and new aircraft factories were built at Columbus, Ohio and Louisville, Kentucky. The dropping of the two atomic bombs on Japan resulted in an unexpected early end to World War II. All of the major U.S. airplane builders including Curtiss-Wright were hit by massive contract cancellations because of the Japanese surrender. In 1946 Curtiss-Wright had only two experimental military models at hand for postwar delivery and no assurance of production orders. Curtiss-Wright was forced to shut down all airplane plants and transfer all units of the Aeroplane Division to their Columbus Plant. The eventual sale of the Airplane Division to North American included design rights to the former Curtiss-Wright airplanes. The Curtiss-Wright Airplane Division, which manufactured airframes, finally closed down in 1951.

Biographical / Historical:
Since its founding in 1913, the history of the Formica Company has been marked by a spirit of innovation and entrepreneurship. The history begins with the discovery of Formica by two men who envisioned the plastic laminate as breakthrough insulation for motors. Later, Formica became a ubiquitous surfacing material used by artists and architects of post-modern design. The various applications of the plastic laminate during the twentieth century give it a prominent role in the history of plastics, American consumerism, and American popular culture.
The Formica Company was the brainchild of Herbert A. Faber and Daniel J. O'Conor, who met in 1907 while both were working at Westinghouse in East Pittsburgh, Pennsylvania. O'Conor, head of the process section in the Research Engineering Department, had been experimenting with resins, cloth, paper, and a wide array of solvents in an effort to perfect a process for making rigid laminate sheets from Kraft paper and liquid Bakelite. O'Conor produced the first laminate sheet at Westinghouse by winding and coating paper on a mandrel, slitting the resulting tube, and flattening it on a press. The finished product was a laminated sheet with the chemical and electrical properties of Bakelite that were cut into various shapes and sizes. O'Conor applied for a patent on February 1, 1913, but it was not issued until November 12, 1918 (US Patent 1,284,432). Since the research was done on behalf of Westinghouse, the company was assigned the patent, and O'Conor was given one dollar, the customary amount that Westinghouse paid for the rights to employees' inventions.
Herbert Faber, Technical Sales Manager of insulating materials, was excited about O'Conor's discovery. Faber saw limitless possibilities for the new material. However, he quickly became frustrated by Westinghouse's policy limiting the sale of the laminate to its licensed distributors. After failing to persuade Westinghouse to form a division to manufacture and market the new material, Faber and O'Conor created their own company. On May 2, 1913, the first Formica plant opened in Cincinnati, Ohio. On October 15, 1913, the business incorporated as the Formica Insulation Company with Faber as president and treasurer and O'Conor as vice-president and secretary. The company began producing insulation parts used in place of or "for mica," the costly mineral that had been used in electrical insulation.
Like most new companies, Formica had modest beginnings. Faber and O'Conor faced the challenge of looking for investors who would let them maintain control over the company. Finally, they met J. G. Tomluin, a lawyer and banker from Walton, Kentucky, who invested $7,500 for a one-third share in the Formica Company. Renting a small space in downtown Cincinnati, Faber and O'Conor began work. The company's equipment list consisted of a 35-horsepower boiler, a small gas stove, and a variety of homemade hand screw presses. By September 1913, Tomluin had brought in two more partners, David Wallace and John L. Vest. With the added capital, O'Conor, Faber, and Formica's eighteen employees began producing automobile insulation parts for Bell Electric Motor, Allis Chalmers, and Northwest Electric.
Initially, the Formica Company only made insulation rings and tubes for motors. However, by July 4, 1914, the company obtained its first press and began to produce flat laminate sheets made from Redmenol resin. Business gradually grew, and by 1917 sales totaled $75,000. Fueled by World War I, Formica's business expanded to making radio parts, aircraft pulleys, and timing gears for the burgeoning motor industry. In the years that followed, Formica products were in high demand as laminate plastics replaced older materials in washers, vacuum cleaners, and refrigerators. By 1919, the Formica Company required larger facilities and purchased a factory in Cincinnati.
During this time, patent battles and legal suits emerged to challenge Formica's success. On June 11, 1919, Westinghouse sued Formica for patent infringement on its laminated gears; Formica won. Later that year, Westinghouse brought two new lawsuits against Formica. The first was for a patent infringement on the production of tubes, rods, and molded parts; the second was over an infringement based on a 1913 patent assigned to Westinghouse through O'Conor. Formica prevailed in both suits.
Legal battles did not deter the company. Having to defend itself against a giant corporation gave Formica a reputation as a scrappy contender. Finally, Faber and O'Conor made a quantum leap in 1927, when the company was granted a U.S. patent for a phenolic laminate utilizing lithographed wood grains of light color, forming an opaque barrier sheet which blocks out the dark interior of the laminate. In 1931, the company received two more patents for the preparation of the first all paper based laminate and for the addition of a layer of aluminum foil between the core and the surface, making the laminate cigarette-proof. These patents would allow Formica to move from a company dealing primarily with industrial material to the highly visible arena of consumer goods.
In 1937, Faber had a severe heart attack which limited his activity within the company. O'Conor continued as president, encouraging new product lines, including Realwood, as a laminate with genuine wood veneer mounted on a paper lamination with a heat-reactive binder. With the introduction of Realwood and its derivatives, manufacturers started
using Formica laminate for tabletops, desks, and dinette sets. By the early forties, sales of Formica laminate were over 15 million dollars. The final recipe for decorative laminate was perfected in 1938, when melamine resins were introduced. Melamine was clear, extremely hard, and resistant to stains, heat, light, less expensive than phenolic resins. It also made possible laminates of colored papers and patterns.
Due to World War II, Formica postponed the manufacturing of decorative laminate sheets. Instead, the company made a variety of war-time products ranging from airplane propellers to bomb buster tubes.
The post-World War II building boom fueled the decorative laminate market and ushered in what would come to be known as the golden age for Formica. The company, anticipating the demand for laminate, acquired a giant press capable of producing sheets measuring thirty by ninety-six inches for kitchen countertops. Between 1947 and 1950, more than 2 million new homes were designed with Formica brand laminate for kitchens and bathrooms.
Formica's advertising campaigns, initially aimed at industry, were transformed to speak to the new decorative needs of consumer society, in particular the American housewife. Formica hired design consultants, Brooks Stevens, and, later, Raymond Loewy who launched extensive advertising campaigns. Advertising themes of durability, cleanliness, efficiency, and beauty abound in promotional material of this time. Advertisers promised that the plastic laminate, known as "the wipe clean wonder," was resistant to dirt, juices, jams, alcohol stains, and cigarette burns. Atomic patterns and space-age colors, including Moonglo, Skylark, and Sequina, were introduced in homes, schools, offices, hospitals, diners, and restaurants across America.
The post-war period was also marked by expansion, specifically with the establishment of Formica's first international markets. In 1947, Formica signed a licensing agreement with the British firm the De La Rue Company of London for the exclusive manufacture and marketing of decorative laminates outside North America, and in South America and the Pacific Basin. In 1948, Formica changed its name from the Formica Insulation Company to the Formica Company. In 1951, Formica responded to growing consumer demand by opening a million square foot plant in Evendale, Ohio, devoted to the exclusive production of decorative sheet material. In 1956, the Formica Company became the Formica Corporation, a subsidiary of American Cyanamid Company. A year later, the international subsidiaries that Formica formed with De La Rue Company of London were replaced by a joint company called Formica International Limited.
The plastic laminate was not merely confined to tabletops and dinette sets. Formica laminate was used for skis, globes, and murals. Moreover, well-known artists and architects used the decorative laminate for modernist furniture and Art Deco interiors. In 1960, Formica's Research and Development Design Center was established, adjacent to the Evendale plant, to develop uses for existing laminate products. In 1966, the company
opened the Sierra Plant near Sacramento, California. Such corporate expansion enabled Formica to market its laminates beyond the traditional role as a countertop surface material.
In 1974, Formica established its Design Advisory Board (DAB), a group of leading designers and architects. DAB introduced new colors and patterns of laminate that gained popularity among artists and interior designers in the 1980s. In 1981, DAB introduced the Color Grid, a systematic organization of Formica laminate arranged by neutrals and chromatics. The Color Grid was described as the first and only logically arranged collection of color in the laminate industry. DAB also developed the Design Concepts Collection of premium solid and patterned laminates to serve the needs of contemporary interior designers.
In the 1980s and 1990s, the corporation continued to produce laminates for interior designers, artists, and architects. In 1982, Formica introduced COLORCORE, the first solid-color laminate. Due to its relatively seamless appearance, COLORCORE was adopted by artists for use in furniture, jewelry, and interior design. The introduction of COLORCORE also marked the emergence of a wide variety of design exhibitions and competitions sponsored by the Formica Corporation. In 1985, Formica Corporation became independent and privately held. Formica continues to be one of the leading laminate producers in the world with factories in the United States, England, France, Spain, Canada, and Taiwan.

Summary:
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.

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:
Introduction
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.
Marconi Companies
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.
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-Ã -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.
Telefunken
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.

Philips Gloeilampenfabriken, Consolidated Electric Lamp Company, Hygrade Sylvania Corporation, Chicago Miniature Lamp Works, and Tung-Sol Lamp Works, Inc., were found guilty and in violation of the Sherman Anti-Trust Act. GE, in particular, negotiated agreements through its wholly-owned subsidiary, International General Electric that divided the world lamp markets. This division permitted GE to have the U.S. market exclusively and bar foreign lamp manufacturers. The domestic licensees' growth was limited by GE to a fixed percentage of its own production and expansion so that over the years a licensee's share of the business was diminished. This restrained trade, and competition by GE unlawfully monopolized the incandescent electric lamp business.
A separate case involving Westinghouse Electric and Manufacturing Co. vs. Beacon Lamp Co., Leopold Rossbach, C. L. Shoninger, A.H. Moses, L.E. Whicher and J.T. Hambay from 1896 to 1898 is also documented through the brief for the complainant and a record of the case.

Biographical / Historical:
Charles Eisler (1884-1973) was born in Hungary to Adolph and Helen Eisler. Charles was the second child of nine: George, Emil, Michael, Leopold, Rudi, Franz, Emma and Lajos. Eisler completed his engineering and mechanical studies by the age of 17 and began an apprenticeship with a local factory. He became a licensed steam engineer and fireman of high pressure boilers. In 1902, he left Hungary for Berlin, Germany, with the goal to immigrate to the United States. In Germany, Eisler worked in a factory in Eberswalde, north of Berlin. The factory manufactured cast-iron pipe and machinery, and Eisler operated a crane loading barges near the factory. Eisler left Eberswalde and returned to Berlin to work as a toolmaker at Allgemeine Electricitäts Gesellschaft' (AEG). He arrived in New York City on the SS Potsdam/Stockholm (I) in November 1904. Because Europeans dominated the field of skilled mechanics and tradesmen in the United States, Eisler easily found employment in East Pittsburgh at Pittsburgh Westinghouse. In 1907, Eisler worked for Studebaker Metzger Motor Company as a tool-designer and tool room foreman.
Eisler returned to Hungary in the spring of 1912 where he took a job as a tool designing engineer with an American owned electrical firm, Standard Electric Company, in Újpest. He married Frieda Schwartz Eisler (d.1962) on December 24, 1912, in Budapest. They had four children: Charles Eisler, Jr., Martha (Eisler) Leff; Ruth (Eisler) Forest; and Constance (Eisler) Smith. In 1914, Eisler, his wife Frieda, and their newborn son Charles, Jr., returned to the United States. Eisler worked at the Westinghouse Lamp Company in Bloomfield, New Jersey, designing machines for building incandescent lamps with tungsten wire. At Westinghouse, Eisler held the position of chief engineer of the equipment division, and he completed the International Correspondence Schools course in mechanical engineering (1918). Eisler left Westinghouse in 1919 to work for Save Electric Corporation of Brooklyn, New York (an independent lamp manufacture), formed by Max Ettiger. At Save Electric, Eisler was equipment engineer superintendent and responsible for designing machines for the production of incandescent lamps.
General Electric (GE), Westinghouse, and RCA had a monopoly on modern incandescent lamp making machinery. The manufacture of lamps and tubes had moved from a low-rate, highly skilled craft work of Edison's Menlo Park to a high-rate, semi-skilled process dominated by GE and others. It was difficult for independent lamp manufacturers, such as Save Electric, to compete. The control and licensing of machinery patents was one method GE used to maintain a virtual monopoly on lamp manufacture throughout the first half of the 20th century. GE purchased Save Electric in 1920 to remove it from the incandescent lamp market. That same year, Eisler lost his job and started his own company, Eisler Engineering Company, to consult and manufacture equipment for producing electric lamps, television tubes, radio tubes, glass products, neon tubes, welding equipment and laboratory equipment. He established a machine shop at 15 Kirk Alley, Newark, New Jersey, where he redesigned many of his machines and drawings and started patenting. By 1924, Eisler's plant doubled in physical size and labor supply, with the radio tube industry peaking in 1929.1 However, the stock market crash of 1929-1930 severely impacted production, and Eisler never again saw the same growth. In 1929, Eisler sold a 49% interest in the company to Frank Bonner.
In June 1933, Eisler and others organized a group of independent manufacturers into the Incandescent Lamp Manufacturer's Association (ILMA). In response to the pressuring tactics of GE, Westinghouse and RCA, the group also documented every lamp maker who went out of business or that was bought by a monopoly member. The ILMA allowed members to pool their resources for patent litigation. "Eisler was the third leading outside supplier of lamp making machinery. It was not licensed by General Electric, and the unlicensed lamp manufacturers obtained most of their lamp making equipment from it. The Eisler equipment was less automatic and of considerably less speed than the machinery used by the General Electric group. However, it was considerably lower in price."2
Eisler Engineering Company was sued at least four times by GE between 1923 and 1928 for alleged patent infringement but won each case. The cases involved four United States patents owned by GE: Van Keuren #1,326,121; Mitchell and White #1,453,594; Mitchell and White #1,453,595; and Marshall #1,475,192. The last three patents address a process used in the manufacture of electric lamps known as "sealing in" of tip-less lamps. The plaintiff, GE, complained that Eisler, the defendant, was infringing. Several GE patents were declared invalid during the proceedings or were withdrawn, and Eisler's U.S. Patent #1,637,989 for tip-less lamps was upheld. See General Electric Company vs. Eisler Engineering Company, 20 F (2d.) 33 (C.C.A., 1927), 26 F (2d.) 12 (C.C.A., 1928), and 43 F (2d.) 319 (C.C.A., 1930). One of Eisler's strongest defenses was a 1916 article he published in Machinery on Tungsten Lamp Manufacture. Eisler defended his case not only for the interest of his own company but also for those who utilized his products as well as those who manufactured under a licensing agreement with Eisler Engineering Company.
In 1954, Charles Eisler, Jr., formerly vice president became president of Eisler Engineering Company, Inc., and Charles Eisler, Sr., became chairman of the board. In 1958, Eisler Senior officially stepped down. In the late 1970s, Eisler, Jr., sold the company to Kahle Engineering Company. Kahle, established in 1920 with its roots in the glass machinery business, provided equipment for the medical device, pharmaceutical, electrical and automotive industries. Today, Kahle focuses solely on the manufacture of assembly machines for medical devices.
Eisler was issued fifty-seven United States patents relating to the mass production of glass articles. His first patent was issued in 1916 (U.S. Patent # 1,209,650) for a turret attachment and his last was issued in 1958 (U.S. Design Patent # DES 182,796) for a spot welder/press type. Eisler received an honorary Doctor of Science degree from Bloomfield College in Bloomfield, New Jersey (1951) and was elected to life membership in the American Society of Mechanical Engineers (1952). He died on October 8, 1973 at the age of 89 in East Orange, New Jersey.

Papers relating to the development of the flexible drinking straw, Friedman's manufacturing company, and Friedman's other inventions, such as an ice cream scoop, fountain pens, and household appliances.
Scope and Contents:
Papers relating to the development of the flexible drinking straw, Friedman's manufacturing company, and Friedman's other inventions, such as an ice cream scoop, fountain pens, and household appliances. Includes company ledgers, preliminary sketches, blueprints, correspondence, a video cassette, and photographs.
The Joseph B. Friedman Papers encompass the years 1915-2000, with the bulk of the material ranging between 1925 and 1965. This collection is a near complete source for the understanding inventive process of an American entrepreneur. In the case of the flexible straw, the evolution of the invention can be traced from early concept drawings through its manufacture and production, to the development of advertising and marketing materials. Records of necessary design modifications in the flexible straw and legal issues concerning Friedman's invention through its various stages are present here. In addition to providing a detailed linear account of the flexible straw, these papers reflect the varied interests and additional accomplishments of Friedman's invention career. The collection is arranged in three series to reflect the subjects of the material, namely personal papers, invention materials, and corporate records. Materials within each series are arranged by topic and type, and then chronologically.
Series 1: Personal Records (c.1920s-1940) contains family photographs, personal correspondence, education and employment records. Friedman's education records are in Subseries A, while the records of his careers in optometry, insurance and real estate are contained in Subseries B. Subseries C contains personal financial records, including bank statements and income tax returns. Correspondence, photographs, family history items and death certificate are located in Subseries D.
Series 2: Invention & Patent Materials (1915-1967) consists of invention records that include original concept drawings, legal records and patents, marketing correspondence, and the business records of Friedman's sole proprietorship invention business, the Commercial Research Company. It is important for researchers to note that information on the assignment of straw patents and their machinery, all associated legal records to those specific issues, as well as patent defense case research, and straw advertising and marketing after 1938 may be found in Series 3. Series 2 is divided into several subseries. Subseries A - I are patented inventions arranged chronologically by patent issue date, and include research and development, legal records and correspondence, and advertising and marketing materials. Subseries J - M contain unpatented inventions and business records, as well as multiple concept drawings and invention lists that refer to both patented and unpatented inventions. Researchers interested in the conceptual development of the straw should review the information contained not only in Subseries E: Drinking Tube and Subseries H: Flexible Straw, but also in Subseries L: Invention Lists & Drawings for straw ideas that were drawn on lists or sketches with other concepts. Additionally, researchers interested in the manufacturing device for the straw should review Subseries I: Apparatus & Method for Forming Corrugations in Tubing, as well as Subseries K: Unpatented Inventions, for the Flexible Straw & Method of Forming Same information.
Series 3: Flex-Straw Corporate Records (1938 - 1967) includes correspondence relating to the company and its formation, financial statements, tax returns, legal documents, patent assignments, royalty information, patent defense case research and records, and documents pertaining to the advertising and marketing of the flexible straw. Researchers should note that all conceptual and developmental details relating to the straw and its manufacture, as well as the original patents and their specifically associated legal correspondence can be found in Series 2. Series 3 is divided into several topically arranged subseries. Subseries A consists of the organizational materials for the company, including the minutes, by-laws and limited employee records. This subseries also contains two day books belonging to Joseph B. Friedman recording his appointments and personal notes from 1947 and 1950. Subseries B includes company related correspondence, organized by the correspondent. It begins with general correspondence, from 1939 - 1963, and continues with the letters of Bert Klein (1945 - 1950), David Light & Harry Zavin (1938 - 1962), and Betty Friedman (1940 - 1954). Much of the operational information on the company may be found in the letters Betty Friedman wrote and received from her brother. Subseries C holds the financial records of the company, including financial statements, ledgers, bank statements, check books, tax returns and royalty statements. Subseries D consists of legal records and correspondence, including such topics as changes in entity type, patent assignments, fair trade agreements and patent defense. Subseries E contains the advertising and marketing records of the company. This includes published material relating to the Flex-Straw specifically, as well as some advertising for flexible straws in general. Pencil concept drawings of Flex-Straw packaging and advertising art are drawn on the reverse of Pette calendar pages, and international advertising materials for the product are also present. Product testimonials, distributor bulletins, and corporate letterhead that traces the progression of company locations can also be found here.
Arrangement:
The collection is ivided into three series.
Series 1: Personal Records, circa 1920s-1940
Series 2: Invention and Patent Materials, 1915-1967
Series 3: Flex-Straw Corporate Records, 1938-1969
Biographical / Historical:
Joseph B. Friedman (1900 - 1982) was an independent American inventor with a broad range of interests and ideas. Born in Cleveland, Ohio on October 9, 1900, Joseph was a first generation American and the fifth of eight children for Jacob Friedman and Antoinette Grauer Friedman. By the age of fourteen, he had conceptualized his first invention, the "pencilite" lighted pencil, and was attempting to market his idea. Over the course of his inventing career, he would experiment with ideas ranging from writing implements to engine improvements, and household products to sound and optic experiments. He was issued nine U.S. patents and held patents in Great Britain, Australia and Canada. His first patent was issued for improvements to the fountain pen on April 18, 1922, (U.S. patent #1,412,930). This was also the first invention that he successfully sold, to Sheaffer Pen Company in the mid 1930s. In the 1920s, Friedman began his education in real estate and optometry. He would use both of these careers at different points in his life to supplement his income while improving his invention concepts. Although he was working as a realtor in San Francisco, California, the 1930s proved to be his most prolific patenting period, with six of his nine U.S. patents being issued then. One of these patents would prove to be his most successful invention - the flexible drinking straw.
While sitting in his younger brother Albert's fountain parlor, the Varsity Sweet Shop in San Francisco, Friedman observed his young daughter Judith at the counter, struggling to drink out of a straight straw. He took a paper straight straw, inserted a screw and using dental floss, he wrapped the paper into the screw threads, creating corrugations. After removing the screw, the altered paper straw would bend conveniently over the edge of the glass, allowing small children to better reach their beverages. U.S. patent #2,094,268 was issued for this new invention under the title Drinking Tube, on September 28, 1937. Friedman would later file and be issued two additional U.S. patents and three foreign patents in the 1950s relating to its formation and construction. Friedman attempted to sell his straw patent to several existing straw manufacturers beginning in 1937 without success, so after completing his straw machine, he began to produce the straw himself.
The Flexible Straw Corporation was incorporated on April 24, 1939 in California. However, World War II interrupted Friedman's efforts to construct his straw manufacturing machine. During the war, he managed the optometry practice of Arthur Euler, O.D., in Capwells' Department Store in Oakland, California, and continued to sell real estate and insurance to support his growing family. Joseph obtained financial backing for his flexible straw machine from two of his brothers-in-law, Harry Zavin and David Light, as well as from Bert Klein, a family associate. With their financial assistance, and the business advice of his sister Betty, Friedman completed the first flexible straw manufacturing machine in the late 1940s. Although his original concept had come from the observation of his daughter, the flexible straw was initially marketed to hospitals, with the first sale made in 1947.
Betty Friedman played a crucial role in the development of the Flexible Straw Corporation. While still living in Cleveland and working at the Tarbonis Company, she corresponded regularly with her brother and directed all of the sales and distribution of the straw. In 1950 Friedman moved his family and company to Santa Monica, California. Now doing business as the Flex-Straw Co., sales continued to increase and the marketing direction expanded to focus more strongly on the home and child markets. Betty moved west in 1954 to assume her formal leadership role in the corporation. Additional partners and investors were added over time, including Art Shapiro, who was initially solicited as a potential buyer of the patent. On June 20, 1969, the Flexible Straw Corporation sold its United States and foreign patents, United States and Canadian trademarks, and licensing agreements to the Maryland Cup Corporation. The Flexible Straw Corporation dissolved on August 19, 1969.
Dr. Joseph Bernard Friedman died on June 21, 1982. He was survived by his wife of over 50 years, Marjorie Lewis Friedman, his four children Judith, Linda, Pamela and Robert, and seven grandchildren

Papers relating to Charlotte Cramer Sachs's life and career as an inventor mainly of food and household-related products: correspondence, photographs, business papers, awards, patents, printed materials, notes, and miscellany. The collection primarily consists of invention-related marketing materials including invention samples and prototypes, notes, clippings, business correspondence, and customer account records.
Scope and Contents:
The records are divided into two series. Series 2 is further divided into eight subseries.
Series 1 documents the inventor's creativity through her artistic, literary, and musical records. Also included are awards and certificates received and materials related to her childhood home. This series contains few photos of Cramer Sachs herself, although a print of one of her paintings, "Portrait of a Lady," circa 1953, seems to be a self-portrait. There are no photos of her husband or daughter in the collection. Also missing is any information related to the inventor's formal education, childhood, the circumstances of her departure from Berlin, marriage, and family life.
Materials in Series 2 constitute the bulk of the collection and are primarily comprised of marketing ephemera, with very few financial and production records. This series gives a broad outline of Cramer Sachs's many inventions documenting Joy Products and wine-related inventions in the most depth.
Series 1: Creative and Artistic Papers, 1933-2002
These records include sheet music, songbooks, stories, and poetry of the inventor's own creation; photographic prints of her artwork; art exhibition materials; publishing company (Crambruck Press) records and published materials; childhood residence ("Haus Cramer") materials, and awards and certificates unrelated to inventions. Artwork and songs make up the bulk of the materials, and are arranged alphabetically by subject. Records in this series provide a context for Cramer Sachs's career as an inventor, although they do not reveal extensive information regarding her personal life or history.
Records relating to artwork include press releases, exhibition photographic prints and negatives, promotional materials, newspaper clippings, notebooks compiled by Cramer Sachs, as well as donation records of artworks given by the inventor to The Cathedral Church of St. John the Divine.
Crambruck Press publishing company is a combined name which incorporates the inventor's surname, Cramer and mother's maiden name, Bruck. These records include a pre-publication notice and order form for a Crambruck Press publication, correspondence from a donor, as well as three Crambruck Press publications: From Boring Dinosaur to Passionate Computer by Livingston Welch, 1968; Poems by Helen H. Shotwell, 1970; and In Search of Harmony by Charlo, 1964.
Haus Cramer materials include photographs, newspaper clippings (many of them in German), correspondence between Cramer Sachs and Stanford University, and floor plans of the house designed in 1912 by German architect Hermann Muthesius. A framed black-and-white photographic print of Haus Cramer is fragile and is housed in a sink matte, box 9.
Poetry materials, songs, and stories are contained in bound books, published songbooks, original sheet music, and copyright records for song words, manuscripts written by Cramer Sachs, as well as correspondence records related to her writings. The song "With Love From New York" was used in the marketing of "Joy New Yorkshire Pudding Mix," and the records contain a vinyl recording which doubles as a marketing piece. Allusions to her husband, Alexander Sachs, and daughter, Eleanor, are found in some of her songs and stories.
Translation materials are comprised of correspondence (mostly in German), as well as Cramer Sachs's complete English translation of the "Stoffel Flies Across the Ocean" story, originally written in German by Erika Mann, circa 1932.
Series 2: Invention Records, 1905-2002
Invention Records contain information related to Cramer Sachs as an inventor and are divided into eight subseries. Materials include: patent related records; samples and prototypes; marketing and advertising materials; newspaper and magazine clippings; business correspondence records; customer account records; Wine Museum materials; and patent searches. These present a broad overview of Cramer Sachs's many inventions, although the majority of information is concentrated in the Household/Office, Food Products, and Wine-related series. Records are arranged chronologically by invention. The final subseries contain patent searches requested by the inventor.
Subseries 2.1: Cramer Products Company and Affiliate Company Records, 1942-2002
Materials include financial records, business correspondence, company awards and certificates, real estate materials, license agreements with outside inventors, a promotion prospectus for the company, and three company stamps (three dimensional). Also included are records of an invention for which Cramer Sachs sought copyright, "Orthodontic Device," 1954, and those having to do with products distributed—not invented—by Cramer Products Company, "Forster Longfresh," 1985. In addition, there are black-and-white photographic prints of an office opening which include images of Cramer Sachs in 1967. These records are arranged chronologically.
These records relate to seven different inventions, each with varying degrees of information. "Combination Key and Flashlight," 1940 was an improvement on previous patents and therefore consists of the earlier patent materials (1913 and 1938), Cramer Sachs's patent application materials, an official, sealed patent application (1940), prototype drawings, correspondence records related to manufacturing and distribution, photographic prints, and a newspaper article. "Cozi-Crib," 1958 and 1968, and "Joy Originals Log Cabin Furniture Set," 1957, records include marketing materials whereas "Holdit," 1972, and "Party Platter," 1962, are minimally represented by one or two photographic prints. "Gaitray" materials consist of four product samples. Materials for "Miracle Knee Tray," circa 1953 include marketing ephemera, a photograph, and two product samples. A prototype for the "Traypron," 1954, is also included. These records are arranged alphabetically by invention name.
Subseries 2.3: Food Products, 1940-1969
Records in this subseries are mostly comprised of Joy Products prepared mix materials. Two exceptions are the small, fragile recipe book, 1940, and the "Caviodka," 1962, records. Business correspondence materials contain those from a food and equipment consultant, the Colgate-Palmolive Company, and Arthur Colton Company, in addition to those relating to the incorporation of Cramer Sachs's "baking mix manufacturing plant" (1945). There are numerous packaging samples of various Joy Products, along with handwritten recipes and notes. An example of early packaging for Joy Products "Early American Muffin Mix" is in flat box 10. This subseries also includes customer surveys and comments, marketing plans and proposals, advertisements, and a marketing portfolio compiled by the inventor. A scrapbook contains Joy Products newspaper clippings, advertisements, marketing ephemera, and photographs of store displays. The scrapbook pages are extremely brittle and are housed in sleeves. Preservation copies are available for research use. These records are arranged chronologically.
Subseries 2.4: Pet Accessories, 1953-1954
This subseries consists of materials relating to three inventions: "Bonnie Stand," circa 1953-1954; "Guidog," 1953; and "Watch-Dog," 1953. Records include photographic prints, marketing materials, printing blocks (for "Bonnie Stand"), as well as a declaration of invention for, and a product sample of, "Watch-Dog." These records are arranged alphabetically by invention name.
Subseries 2.5: Games, 1961-1969
The inventor created two games: "Domi-Notes," circa 1961 and "Musicards," circa 1969. "Domi-Notes" materials include an order form citing the distributor as G. Schirmer, Inc. and the addressee as Walter Kane and Son, Inc., and three games two in cardboard boxes, (fragile) and one housed in the original hard plastic case. Records relating to "Musicards" consist of two game samples including directions for playing.
Subseries 2.6: Wine-Related, 1966-2002
Wine-related records cover twenty distinct inventions and range from specialty cabinets—which make-up the bulk of the materials—to bottle accessories such as the "Bottle Bib" and the "Cramanna Bottle Ring." The type and number of records vary, with the majority concentrated in the "Cool-Safe," "Cramarc Multiple Cabinet," "Modern Wine Cellar," and "Well Tempered Systems" folders. Records in invention-specific folders are arranged alphabetically and include marketing materials, press releases, photographic prints and some negatives, cabinet drawings, brochures, order forms, correspondence, as well as product samples of "Bottle Bibs."
Customer account records are arranged alphabetically and consist of billing statements, invoices, receipts, blueprints, correspondence, cabinet drawings, customer feedback, bills of lading, and memoranda. Letters from David H. Wollins laud Cramer Sachs's cabinet as "the finest home wine storage system in the world." Examples of how the inventor handled an unsatisfied customer can be found in the Col. Charles Langley folder.
Miscellaneous wine-related materials follow the customer account records. Included are advertising ephemera, photographs, and newspaper clippings originally assembled into a binder by Cramer Sachs. Taped to the inside front cover was a cut-out from a magazine advertisement which reads, "If you stick with the herd, you could end up as a lamb chop." Miscellaneous materials also include unlabeled cabinet drawings, photographic prints, competitor materials, photocopies from Grossman's Guide to Wines, Spirits, and Beers, as well as marketing materials and newspaper clippings covering a range of wine-related inventions. These records are arranged alphabetically by subject.
The final section of the wine-related subseries documents the development and eventual dissolution of The Wine Museum of New York. Records are arranged chronologically and include a provisional charter; an extension of the provisional charter; a newspaper clipping; outreach correspondence; a binder of wine museum materials including brochures, event invitations, exhibition opening cards, board member profiles, a press release, and newspaper clippings; wine museum exhibition information; and records related to the dissolution of the museum.
Subseries 2.7: Temperature and/or Humidity Controlled Devices, 1968-2002
This subseries documents the inventor's temperature and/or humidity controlled inventions that do not relate to wine. Cramer Sachs created the "Well Tempered Cabinet" for both wine and musical instruments; it is documented in this and the wine-related subseries. These records cover eight distinct inventions which range from specialty cabinets for musical instruments, furs, and cigars to devices designed to cool the body. Records relate to marketing, invention-specific business correspondence, confidential information and competition agreements, and include photographic negatives and prints. Miscellaneous cabinet drawings, cigar-related materials, and newspaper articles are also included. Records are arranged alphabetically by invention name followed by miscellaneous materials.
Subseries 2.8: Patent Searches, 1905-1980
Records in this subseries include correspondence as well as copies of several patented inventions for which Cramer Sachs requested information.

Biographical / Historical:
Charlotte Cramer Sachs was born in Berlin, Germany on September 27, 1907. Her father, Hans Siegfried Cramer, worked as a businessman for a successful grain import and export company whose innovative enterprises included the import of soy beans from Eastern Europe. In 1903, Hans married Gertrud Bruck, one of the first women to attain her Abitur, somewhat similar to an American high school diploma, at age eighteen. Bruck's formal education ended there, as her wish to attend university was thwarted by her father Adalbert, a judge who insisted that she remain at home. The couple settled in Berlin and had two children—Frederick H., born March 2, 1906, and Charlotte. From 1913 to 1924 The Cramers lived in the Berlin Dahlem suburb occupying "Haus Cramer," a villa built in 1912 to their specifications by German architect Hermann Muthesius.
On September 12, 1924, Cramer Sachs married Donald Samuels, a top executive of the Manhattan Shirt Company and moved to New York from England where their daughter Eleanor was born on June 11, 1926. Several years later, the couple divorced. Mother and daughter lived together in London for a few years before moving back to New York around 1936. Charlotte's parents relocated to New York at the same time, after a brief stay in London following their flight from Berlin after Hitler's rise to power. In August 1945, Charlotte Cramer married Alexander Sachs, a leading economist who had introduced Albert Einstein to President Franklin Delano Roosevelt and acted as advisor to the President.
Although she established her business career in America, Cramer Sachs retained fond memories of the house and extensive grounds in Dahlem. In 1977 she composed the song "A Salute to Berlin" to commemorate the designation of Haus Cramer as one of the city's historic landmarks. In 2000, she donated a painted portrait of herself from the time she had lived in Haus Cramer to the villa's new owner, Stanford University. The house retains additional significance in the context of this collection because Cramer Sachs credited its wine cellar—unusual in that it provided a separate, climate controlled environment for red and white wines—as an inspiration for her line of custom-built, vibration-free wine storage devices, which would later make Cramer Products Company a household name among wine connoisseurs.
While she did not attend university her pursuit of learning continued throughout her life as she studied poetry, musical composition, and the fine arts. Cramer Sachs often told her niece, Lilian Randall, that she wished she had received further education, although her public art exhibitions, poetry awards, numerous original songs, the establishment of Crambruck Press (her own publishing company), as well as language fluency in French, English, and German, are testaments to this inventor's intellectual curiosity and development. Evidence of Cramer Sachs's entrepreneurial spirit surfaced in her early thirties with her first patent: Improvements in Combined Key and Flashlight, July 16, 1940, patent number 2,208,498.
In 1940, Cramer Sachs completed courses from the New York Institute of Dietetics, an effort spurred by the onset of her daughter's diabetes. With financial assistance from her parents in the early 1940s, Cramer Sachs developed Joy Products prepared mixes, marking the beginning of a successful career in inventing. "We were a pioneer in that field," said Cramer Sachs of her baking mix manufacturing company, an operation that consisted of a Bronx neighborhood factory employing ninety workers. The enterprise began with corn muffin and popover mixes and expanded into frostings, puddings, and breads. Newspaper clippings from the time promoted Joy packaged mixes as ideal gifts for "the boys overseas" who were in locations where it was "impossible to get together the makings of a cake." Cramer Sachs refused an early offer to sell her mix formulas which were subsequently copied and exploited by larger, more powerful companies. Joy Products, whose name was chosen to express the inventor's delight in creativity, remained in business as a modest one-woman operation for over twenty years before succumbing to competition.
Cramer Sachs created another highly successful invention, the specialty wine cabinet, more than twenty years after she founded Joy Products. In addition to her memories of visits with her father to the wine cellar in her family's German villa, further motivation came from an interest—though she hardly drank it at all—in wine and recognition that "standard cooling and refrigerating appliances [were] too cold for wines." Reportedly, Cramer Sachs "started looking for [an appropriate device] and could not find one," and thus the impetus to invent took shape. The "Modern Wine Cellar," 1966, was an early example of over twenty wine-related inventions, most of them storage devices. A mention of her product in Grossman's Guide to Wines, Spirits, and Beers, increased demand among wine lovers and may have prompted Cramer Sachs to state that she "should find a good market" for her newest invention line. Testimony from David H. Wollins, a successful New York lawyer and customer of Cramer Sachs, lauded the cabinet as "the finest home wine storage system in the world." She framed his letter and hung it in her office at 381 South Park Avenue, her base operation where she employed one or two part-time helpers from the 1960s until her death in 2004.
The inventor took great joy in music, expressed in her own numerous compositions and her creation of the games "Domi-Notes" and "Musicards" in 1961 and 1969. Her fondness for music also prompted the expansion of her specialty cabinets to include temperature and humidity controlled devices for storing a variety of items, most notably the "Well Tempered Cabinet for Musical Instruments," which Cramer Sachs first designed for legendary violinist Isaac Stern. Soon the inventor began producing similar cabinets for the storage of cigars, furs, and documents.
Described by her niece as "shy with people but a great admirer of talent, intellect, and humanity," Cramer Sachs also "harbored a great love for animals." She invented several pet accessories in the early 1950s, including: "Watch-Dog," a dog collar with a time piece; "Bonnie Stand," a holder fashioned to accommodate disposable food bowls; and "Guidog," an early version of a retractable dog leash.
In 1972, Cramer Sachs suffered the loss of her only child, Eleanor, and in the summer of the next year her husband Alexander passed away. She continued her "business of creating new product ideas" for the remainder of her life. The most recent invention materials represented in the collection are those for the "Conservator" from 2002, a temperature and humidity controlled device with compartments to store a variety of items. In her last telephone conversation with her niece, on March 10, 2004, Cramer Sachs expressed her hope that she would feel "strong enough to get to the office the next day or so." The inventor died the following day at the age of 96.

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.

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.
