The collection includes materials that span the entire history of the growth of the radio industry. It is useful for those historians and other researchers interested in technological development, economic history, and the impact of applications of technology on American life.
Scope and Contents:
The materials accumulated in this collection represent the overriding collecting passion of one individual, George H. Clark. The collection forms a documentary record of over half a century of the history of radio, with the greatest emphasis on the period 1900-1935.

The collection includes materials that span the entire history of the growth of the radio industry. It is useful for those historians and other researchers interested in technological development, economic history, and the impact of applications of technology on American life.

In particular, the collection is rich in biographical information on the men who developed the technical aspects of radio and the industry; information on the inception, growth, and activities of radio companies, most notably the National Electric Signaling Company and RCA; and in photographs of all aspects of Radioana.

While most materials document technical aspects of radio, there is much information (e.g. Series 109, 134) on broadcasting and on the early history of television.

The collection, housed in over 700 boxes (about 276 linear feet), was organized into 259 numbered "classes" or series by Clark. Sixty series numbers were never used or were eliminated by Clark and combined with other series. The unused numbers are scattered throughout the filing system. The collection also includes material from series that were eliminated. These materials were never reclassified and are included as an unprocessed series at the end of the series descriptions. The collection also contains material that was never assigned a "class" designation by Clark (Lettered Series: D, E, F, G, H).

The arrangement of the collection is Clark's own; his adaptation of the Navy filing system he helped devise in 1915. Clark periodically revised the filing system and reclassified items within it.

Clark assigned class numbers to types of equipment (e.g. broadcast receivers), systems (impulse-excited transmitters and systems), scientific theories (circuit theory), and topics (company history, biography). Box 1 contains descriptions of the classification system.

When Clark classified an item and filed it he also assigned a serial number. This classification begins with 1 (or 1A) for the first item in the class and continues with successive numbers as items were added. As a consequence, the order of individual items within a series reflects the order in which Clark filed them, not any logical relationship between the items. Clark created cross references for items dealing with more than one subject by making notations on blank sheets of paper placed in related series.

Clark made cross references between series when there was no logical relationship between them; that is, when a person using the collection would not normally look in the series. For example no cross reference would be made of an engineer from series 87 (portraits) to series 4 (biography), but one would be made from series 87 to series 142 (history of television) if the item showed the engineer, say, working on a television installation.

Clark created the insignia "SRM" as the sign on the bottom of all sheets of paper numbered by him for binding. SRM stood for Smithsonian Radio Museum. This replaced the earlier though not greatly used sign "CGM." For a time about 1930, the class number on each sheet was preceded by these: "C.G.M.", for Clark, Martin, and Goldsmith, the earliest contributors to what would become the Clark Radioana Collection. After about 1933-34 Clark used C.W.C. for Clark Wireless Collection.

There are many photographs located in most series throughout the collection. But there are also three exclusive photographic series. Lettered series A, B, C. See index; and also series descriptions under lettered series.
The collection is divided into 223 series.

Biographical / Historical:
George Howard Clark, born February 15, 1881, at Alberton, Prince Edward Island, Canada, emigrated to the United States at the age of fourteen. He worked as a railroad telegraph operator for the Boston and Maine Railroad during high school and college. In his unpublished autobiography he wrote:

In 1888, when I was a lad of seven, I suddenly blossomed out as a scrapbook addict, and for years I gave up boyhood games for the pleasure of sitting in a lonely attic and 'pasting up' my books ... By 1897, in high school, I graduated to beautiful pictures, and made many large size scrapbooks ... Around that time, too, I became infatuated with things electrical, and spent many evenings copying in pen and ink the various electrical text books in the Everett, Mass., Public Library. Clark began collecting material pertaining to wireless or radio in 1902. In 1903 he graduated from the Massachusetts Institute of Technology with a Bachelor of Science degree in Electrical Engineering. During his last year of college he specialized in radio work under the instruction of Professor John Stone Stone and after graduation went to work for Stone's radio company, the Stone Telegraph and Telephone Company, of Boston.

In 1908 Clark took a competitive examination open to all wireless engineers in the United States and entered the civilian service of the Navy. He was stationed at the Washington Navy Yard, with special additional duty at the Navy's Bureau of Steam Engineering and at the National Bureau of Standards.

In 1915 Clark helped devise a classification system for Navy equipment, assigning a code number to each item. This system of classification for blueprints, photographs, reports, and general data, was prepared by Arthur Trogner, Guy Hill, and Clark, all civilian radio experts with the US Navy Department in Washington. In 1918 Clark adopted the 1915 Navy classification system for organizing the radio data he was accumulating. Clark created the term "Radioana" at this time. He began spending his evenings and weekends pasting up his collection and numbering pages. At this time he bound the accumulated material. It totaled 100 volumes.

In July 1919, after resigning from the Navy, Clark joined the engineering staff of the Marconi Telegraph Company of America, which became part of the Radio Corporation of America (RCA) later the same year. His first work was at Belmar and Lakewood, New Jersey, assisting the chief engineer, Roy A. Weagant, in his development of circuits to reduce the interference caused by static (static reduction). Clark and his wife were assigned to the unheated Engineer's Cottage. His wife decided not to stay and left for Florida. Clark moved his trunks of wireless material to the heated RCA hotel at Belmar and spent most of the winter "pasting." As Clark mentions, "From that time on I was wedded to scraps."

After a year of work in New Jersey, Clark was assigned to the sales department in New York, where he devised the "type number system" used by RCA. This type number system, for example, gave the designation UV 201 to the company's first amplifier tube.

From 1922 to 1934 Clark was in charge of RCA's newly created Show Division, which held exhibits of new and old radio apparatus at state fairs, department stores, and radio shows. About 1928 Clark started an antique radio apparatus museum for RCA. RCA's board of directors announced:

Recognizing the importance of providing a Museum for the Radio Art to house the rapidly disappearing relics of earlier days, and the desirability of collecting for it without further delay examples of apparatus in use since the inception of radio, the Board of Directors of RCA has made an initial appropriation of $100,000, as the nucleus of a fund for the establishment of a National Radio Museum. A plan for ultimately placing the museum under the wing of the Smithsonian Institution was coupled with the goal of the Institution's gathering the largest possible library of wireless data.

Around 1933 the RCA traveling exhibition program ended and Clark started classifying his collected "radioana" material. The objects of the museum were eventually turned over for exhibit purposes to the Rosenwald Museum in Chicago and the Henry Ford Museum in Dearborn, Michigan, when space was not forthcoming at the Smithsonian. A list of objects sent to the two museums (with tag and case numbers) is in Series 1, Box A. The "radioana" collection remained under Clark's care during the 1930s, and became of increasing use to RCA. Clark continued to add to the material.

Between 1934 and 1942 Clark was in court many times regarding patent infringements. Clark's wireless data was useful and he testified frequently, for example, in RCA's suit against the United States in the Court of Claims over the Marconi tuning patents and in the Westinghouse Company's suit against the United States over the heterodyne. Patent specifications and material regarding these and other radio industry suits are found throughout this collection.

In 1946 RCA retired George Clark and denied him space to house his "radioana" collection. Clark wished to remain in New York and house the collection somewhere in the city where it would be open at all times to the public and where it would be maintained. He hoped to continue cataloguing the collection and writing books from its information. He wanted to keep the collection under his control for as long as he was capable of using it.

George H. Clark died in 1956 and his collection was subsequently given to the Massachusetts Institute of Technology. In 1959 the collection was given to the Smithsonian's new Museum of History and Technology, where space was available to house it. The collection remained in the Division of Electricity until the spring of 1983 when it was transferred to the Archives Center.
Brief Company Histories From The Radio Industry, 1900-1930s:

At the end of the nineteenth century, when Guglielmo Marconi began his first wireless company, Western Union, Postal Telegraph, and the American Telephone and Telegraph Company (AT&T) were the major enterprises in electrical communications. General Electric, Western Electric, and Westinghouse were the major producers of electrical equipment. All these earlier developments set the stage for the expansion of the radio industry.

General Electric, which dominated the lighting industry, was formed in 1892 as a merger of the Edison and Thomson-Houston companies. It was active in building central power station equipment; controlled nearly all the important early patents in electric railways; took a leading part in the introduction of trolley systems; and was the principal supplier of electric motors. Westinghouse promoted the alternating current system and installed the first AC central station in Buffalo, NY, during the winter of 1866-1867. After years of patent litigation, in 1896 GE and Westinghouse agreed to share their patents on electrical apparatus.

American Bell Telephone Company purchased Western Electric in 1881. Western Electric had a strong patent position in telephone equipment and in industrial power apparatus, such as arc lamps, generators, motors, and switchboard equipment.

Until RCA was formed in 1919, these established electrical companies played no active part in the early development of the American radio industry. They were in difficult financial positions, reorganizing, or concentrating their efforts and resources on improving their existing products.

The revolution in "wireless" technology, which began in earnest after 1900, centered in New York City, home of the Lee de Forest and American Marconi companies, and in Boston, headquarters of John Stone Stone and Reginald Fessenden.

Information in this section was compiled from the Clark Collection; the Invention and Innovation in the Radio Industry by W. Rupert Maclaurin, Macmillan Company, New York, 1949; and Radio Pioneers, Institute of Radio Engineers, Commemorating the Radio Pioneers Dinner, Hotel Commodore, New York, NY, November 8, 1945.

The De Forest Companies

Lee De Forest (1873-1961), inventor of the three-element vacuum tube or triode (1906) and the feedback circuit, was one of the first Americans to write a doctoral thesis on wireless telegraphy: "The Reflection of Short Hertzian Waves from the Ends of Parallel Wires," Yale University, 1899. The grid-controlled tube or audion of De Forest was first a radio detector, 1906-1907; in 1912 was adapted to an amplifier; and later to an oscillator. When it was perfected as a high vacuum tube, it became the great electronic instrument of electrical communications.

De Forest began work in the Dynamo Department at the Western Electric Company in 1899. Six months later he was promoted to the telephone laboratory. In 1900 De Forest went to work for the American Wireless Telegraph Company where he was able to carry out work on his "responder." However, after three months when De Forest refused to turn over the responder to the company, he was fired.

In the following year De Forest had a number of jobs, was active as an inventor, and created numerous firms to manufacture his inventions. In 1901 De Forest joined with Ed Smythe, a former Western Electric colleague and a collaborator in his research, to found the firm of De Forest, Smythe, and Freeman. Between 1902 and 1906 De Forest took out thirty-four patents on all phases of wireless telegraphy. The responder that he had been working on for so long never proved satisfactory.

The numerous De Forest companies, reflected his many interests and his inability to carry one project through to a conclusion. Unlike Marconi, but similar to Fessenden, De Forest had great inventive skill which resulted in a great number of companies; but none lasted long. The original partnership of 1901 led to the Wireless Telegraph Co. of America (1901), the De Forest Wireless Telegraph Company (Maine) (1902), and the American De Forest Wireless Telegraph Company (1903), to name a few.

The American De Forest Wireless Telegraph Company was incorporated after De Forest met a stock promoter, Abraham White. While many stations were built by this company, many never sent a message due to static interference. In 1907 two speculators from Denver with large holdings of company stock put the company out of business. The assets were sold to a new company that these speculators organized, the United Wireless Telephone Company. De Forest was forced to resign. He took the triode patents with him.

De Forest joined with one of White's stock salesmen, James Dunlop Smith, and together with De Forest's patent attorney, Samuel E. Darby, they formed a new corporation, the De Forest Radio Telephone Company in 1907. This company set out to develop wireless communication by means of the radio telephone.

In January 1910 De Forest staged the first opera broadcast, with Enrico Caruso singing. The Radio Telephone Company went bankrupt in 1911 following an aborted merger with North American Wireless Corporation. In 1913 he reorganized the company as the Radio Telephone and Telegraph Company and began producing the triode.

The Marconi Company brought a patent suit, claiming the triode infringed on the Fleming valve to which it had rights. In 1916 the court decided that Marconi had infringed the three element De Forest patent and that De Forest had infringed the two element Fleming valve. The result was that neither company could manufacture the triode.

In 1920 RCA acquired the De Forest triode rights through cross-licensing agreements with AT&T which had recently purchased the rights to it. De Forest's company was no match for GE, Westinghouse, and RCA. The De Forest Radio Company (1923) went bankrupt in 1928, was reorganized in 1930, and went into receivership in 1933. RCA eventually purchased its assets.

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.


The development of the radio industry accelerated after 1912. This was due to several factors, the most important of which was the passage of legislation by the US government requiring ships at sea to carry wireless. This created a market incentive and spurred the growth of the industry. Also, with the outbreak of World War I, the larger electrical companies turned their manufacturing output to radio apparatus, supporting the war effort. Three firms were prominent in this industrial endeavor: AT&T, GE, and Westinghouse.

AT&T's early contributions to this effort centered on their improvements of De Forest's triode, particularly in the evolution of circuits, the redesign of the mechanical structure, and an increase in the plate design. The importation of the Gaede molecular pump from Germany created a very high vacuum. The resulting high-vacuum tube brought the practical aspects of the wireless telephone closer to reality. By August 1915 speech had been sent by land wire to Arlington, Va., automatically picked up there via a newly developed vacuum-tube transmitter, and subsequently received at Darien, Canal Zone. By 1920 AT&T had purchased the rights to the De Forest triode and feedback circuit, and had placed itself in a strong position in the evolution of radio technology.

GE centered its efforts on the alternator, assigning Ernst F. W. Alexanderson to its design, and on further development of vacuum tube equipment for continuous wave telegraph transmission. By 1915 Alexanderson, Irving Langmuir, William D. Coolidge, and others had developed a complete system of continuous wave transmission and reception for GE.

As can be seen, both AT&T and GE were diverting major time and expenditures on vacuum tube research. This inevitably led to patent interferences and consequently, to cross-licensing arrangements.

Westinghouse was not in the strategic position of GE and AT&T. Nevertheless, during the war it did manufacture large quantities of radio apparatus, motors, generators, and rectifiers for the European and American governments. Postwar moves led Westinghouse into full partnership with the other two companies.

By the end of the war, all three companies had committed significant resources to wireless. They were hampered internationally, however, by the Marconi Company's dominant status, and in the United States they were blocked by opposing interests with control of key patents.

The US government also was concerned with this lack of solidarity in the wireless industry and over the British domination of the field worldwide. This impasse set a fascinating and complicated stage for the formation of the RCA.

Owen D. Young, legal counselor for GE, was instrumental in breaking the impasse. Through an innovative and far-reaching organizational consolidation, Young was able to persuade British Marconi that persistence in monopoly was a fruitless exercise, because of the strong US government feelings. Marconi, realizing the harm of a potential American boycott, finally agreed to terms. GE purchased the controlling interest in American Marconi, and RCA was formed. Young was made chairman of the board of RCA, while Edwin J. Nally and David Sarnoff of the old American Marconi were appointed president and commercial manager respectively.

On July 1, 1920, RCA signed a cross-licensing agreement with AT&T. The telephone company purchased one half million shares of RCA common and preferred stock for several considerations -- the most important being that all current and future radio patents of the two companies were available to each other royalty-free for ten years. Many provisions of these agreements were ambiguous and led to later squabbles between the RCA partners.

In May 1920 Westinghouse, which had an efficient radio manufacturing organization, formed an alliance with the International Radio and Telegraph Company (NESCO's successor). Westinghouse's part ownership gave them control of Fessenden's patents, particularly continuous-wave transmission and heterodyne transmission. Westinghouse also wisely purchased in October of 1920 Armstrong's patents on the regenerative and superheterodyne circuits -- which also included some of Columbia University professor Michael Pupin's patents. This placed Westinghouse in a strong bargaining position vis-à-vis RCA and in their new consolidated corporation. Westinghouse joined the growing group of radio companies on June 30, 1921. With these mergers, RCA agreed to purchase forty percent of its radio apparatus from Westinghouse and sixty percent from GE.

Through these and other legal arrangements, RCA obtained the rights to over 2,000 patents. These amounted to practically all the patents of importance in the radio science of that day. As a result, other firms in the radio industry, for example, the United Fruit Company and the Wireless Specialty Apparatus Company, entered into cross-licensing arrangements with RCA.

RCA also made arrangements internationally with the three dominant companies in radio communication in their respective countries. British Marconi, Compagnie Generale de Telegraphie sans fil, and Telefunken. Each corporation was given exclusive rights to use the other companies' patents within their own territories.

The rise of amateur radio in the 1920s and, to a greater extent, the demand for new products by the general public contributed to the rise of the broadcasting industry. This put a strain on the earlier agreements between the major radio corporations and between 1921 and 1928 there was a struggle over patents for control of the evolving medium.

An initial attempt by AT&T to control the broadcasting industry -- using its earlier cross-licensing agreements to manufacture radio telephone transmitting equipment -- began with AT&T's disposal of RCA stock holdings in 1922-1923. It ended in 1926 with a new cross-licensing agreement which gave AT&T exclusive patent rights in the field of public service telephony and gave GE, RCA, and Westinghouse exclusive patent rights in the areas covered by wireless telegraphy, entertainment broadcasting, and the manufacture of radio sets and receiving tubes for public sale.

In 1926 after the agreements were finalized, RCA, GE, and Westinghouse joined forces and established the National Broadcasting Company (NBC). Fifty percent of the stock went to RCA, thirty percent to GE, and twenty percent to Westinghouse. The new company was divided into three divisions: the Red, Blue, and Pacific Networks. Independent, competing networks soon emerged. William S. Paley and his family formed the Columbia Broadcasting System (CBS) in 1927. The Mutual Broadcasting System was formed in 1934.

By 1928 RCA had strong patent positions in all major areas of the radio industry, including the research, development and manufacture of vacuum tubes and speakers. Most small companies entering the industry in the 1920s produced their products based on prior research by others and on expired patents. An RCA license, therefore, was essential for the manufacture of any modern radio set or vacuum tube.

In the late 1920s new developments in the reproduction of sound, produced significant changes in the phonograph industry. Among those new developments were the introduction of the electronic record, and the marketing of the Radiola 104 Loudspeaker in 1926. In 1929 RCA purchased the Victor Talking Machine Company. This changed not only the quality but the sales of the phonograph and the phonograph record. A new entertainment industry was born and an ever-expanding market for consumer products was created with cultural implications that continue today.


German industrialists were eager to break the Marconi Company's monopoly. Although Marconi had patents on his inventions in Germany, the Germans developed a rival system through the Telefunken Corporation, incorporated in 1903, based on the inventions of Professor Ferdinand Braun, Dr. Rudolf Slaby, and Count George von Arco.

Before 1903 the Braun-Siemens and Halske system had been developed by Gesellschaft fur Drahtlose Telegraphie (GFDT). The Slaby-Arco system had been developed by Allgemeine Electrizitats-Gesellschaft. After litigation over patents, the German court handed down a decision in favor of the GFDT. The Kaiser, with national interests in mind, ordered that the rivalry cease. The two systems were amalgamated under GFDT, and became known as the Telefunken.

In March Marconi wireless telegraph service begins between islands of the Hawaiian group. On December 12, Marconi receives transatlantic signal at St. John's, Newfoundland from Poldhu, Cornwall, England. The Canadian government orders two Marconi telegraph sets for use at coastal points along the Strait of Belle Isle.

1901 -- Fessenden procures US patent no. 706737 for a system of radio signaling employing long waves (low frequency). De Forest develops a system of wireless telegraphy in Chicago. 1903-06 10,000 to 50,000 cycle machines, 1 kW, are developed by Steinmetz and by Alexanderson of GE for Fessenden. 1905 Marconi procures patent number 14788 in England, covering the invention of the horizontal directional antenna.

1906 -- At Brant Rock, Massachusetts, Fessenden employs a generator of one-half kW capacity, operating at 75,000 cycles, for radio purposes. He succeeds in telephoning a distance of eleven miles by means of wireless telephone apparatus.

1907 -- De Forest procures a U. S. patent for an audion amplifier of pulsating or alternating current.

1908 -- Marconi stations in Canada and England are opened for radio telegraph service across the Atlantic. Fessenden constructs a 70,000-cycle alternator with an output of 2.5 kW. at 225 volts, for radio signaling purposes. He reports successful radio telephone tests between Brant Rock and Washington, DC, a distance of 600 miles.

1909 -- US House of Representatives passes the Burke Bill for the compulsory use of radio telegraphy on certain classes of vessels. The United Wireless Telegraph Company and the Radio Telephone Company of New York (De Forest and Stone systems) begin the erection of radio stations in the Central and Western states. Marconi shares with Ferdinand Braun of Germany the Nobel prize in recognition of contributions in wireless telegraphy.

The House of Representatives passes a resolution on July 5, authorizing the President to take over management of telegraph and telephone systems due to war conditions.

1919 -- Bills are introduced in Congress for permanent government control of radio stations. The widespread resentment of amateurs has more to do with the defeat of these bills than the objections of commercial companies. Roy Alexander Weagant, New York, reports having developed means of reducing disturbances to radio reception caused by atmospherics or static. This is the first successful static-reducing system. GE purchases the holdings of the British Marconi Company in the Marconi Wireless Telegraph Company of America, the name of the latter company being changed to Radio Corporation of America (RCA) in October. Edward J. Nally is elected president of the new company.

The government calls for bids for the sale of large quantities of surplus radio and telegraph and telephone apparatus purchased for war needs and not used.

1921 -- RCA develops Vacuum tubes UV-200(detector) and UV-201(amplifier) -- both triodes with brass shells known as the UV base, and incorporating a filament that required 1 ampere at 5 volts for operation -- for storage battery operation; and at the same time also released to the public the WD-11 for dry cell operation, which employed an oxide-coated tungsten filament. RCA station at Rocky Point, Long Island, opens on November 5. WJZ station established by the Westinghouse Company in Newark, NJ. RCA broadcast station at Roselle Park, NJ (WDY) opens on December 15. It continues operation until February 15, 1922, when its operation is transferred to WJZ, Newark, previously owned by Westinghouse. RCA installs 200-kW alternator at Tuckerton, NJ.

Collection descriptions
Archival materials
circa 1895-2001
bulk 1898-1951
Scope and Contents:
The Edward S. Curtis papers and photographs, circa 1895-2001 (bulk 1898-1951) primarily relate to Curtis's work on his opus, the North American Indian (NAI), although other subjects are documented as well. The papers relate closely to the Edward S. Curtis papers at the University of Washington Libraries Special Collections (UW), as that collection was donated by Curtis's daughter Florence Graybill and appears to be part of the same body of materials that was maintained by Curtis, and after his death, by Florence. Occasionally a correspondence exchange or manuscript draft is divided between the National Anthropological Archives and UW. Also found in both collections are notes, mostly dated 1951, in Curtis's handwriting on slips of paper or the document itself that gives an explanation of the document.

The collection includes correspondence, research notes, NAI files and promotional material, writings and memoirs, a small amount of material relating to a complaint regarding his reporting in NAI of certain Pueblo ceremonies, and correspondence and other documents relating to his gold mining interests. Also included are papers of Florence Graybill, who published on Curtis after his death and maintained contacts with various individuals and entities involved in Curtis exhibits, publications, and sales.

The correspondence exchanges are almost exclusively NAI related and document the relationships Curtis had with various influential people, including Gifford Pinchot, Joseph Blethen, Jacob Riis, William Farabee, Smithsonian scholars Frederick Webb Hodge and Matilda Coxe Stevenson, and the immediate and extended family of Theodore Roosevelt. Included are letters of introduction for Curtis as he sought to promote his work.

The research notes consist of a small mixture of writings on field experiences as well as maps used during his fieldwork (the bulk of Curtis's fieldnotes and NAI manuscripts are at the Seaver Center in the Los Angeles County Museum of Natural History). The NAI files chiefly contain material promoting the work, such as published reviews, articles, and ephemera, but there are a few North American Indian Inc. business records (the bulk of the business records are maintained at the Pierpont Morgan Library). Of note is a lengthy annual report for the North American Indian, Inc., in which Curtis explains difficulties encountered in the fieldwork and volume publication. Related to his NAI work are letters and other materials documenting a 1934 complaint from Harold Ickes, Secretary of the Interior on Curtis's reporting of certain Pueblo ceremonies, as well as Curtis's response.

The writings comprise manuscript drafts on various topics. Most are short, stand-alone stories relating to his NAI work, often relaying a story about his own experiences. Similar stories can be found in Florence Graybill's papers, as she published some of them after his death. Also part of the writings are drafts for several chapters of Curtis's unpublished memoir, "As it Was."

Curtis's interest in gold mining is represented in correspondence and other material dating from 1938-1950. Most of the letters are between Curtis and his son Harold. Curtis's invention of a concentrator for separating fine gold from placer tailings is also documented in photographs and drawings.

Florence Graybill's papers pertain to writings, talks, and projects relating to Curtis after his death. Included are publication files for Graybill's biography of Curtis written with Victor Boesen, Visions of a Vanishing Race, as well as other of her articles and book reviews. Graybill's correspondence reveals her commitment to assist scholars and others interested in researching and exhibiting Curtis material, as well as her communication with individuals having a commercial interest in Curtis. Also present are Graybill's lecture notes for talks given, and articles and newspaper features on Curtis written by others.

The photographs in this collection primarily relate to Curtis's NAI work (1898-1927) and are a mix of original and working copy negatives, prints, and transparencies. The original negatives are remarkable in that they reveal some of Curtis's working methods in crafting his images through pencil and other enhancements, as well as showing removal of unwanted items from the image. Also of note are two original logbooks used for recording negatives from approximately 1895-1916. The majority of the prints appear to be silver gelatin prints made for reference; however, there are a fair number of platinum prints as well as several blue-toned silver prints in the collection. There are only a few cyanotypes.

Among the photographs is a deerskin-bound photograph album containing Harriman Alaska Expedition and NAI photographs, representing some of Curtis's earliest Native American subjects. These include images of people from the Puget Sound area as well as from his 1900 trip to the Blackfoot reservation. There are no annotations in the album; however, tucked among the pages are a few small notes of identification in Curtis's handwriting.

Photographs documenting other subjects are also present to a lesser degree. Among these are photographs of Curtis's Seattle photography studio, a 1915 Grand Canyon trip, hop field workers in the Puget Sound area, and Curtis's illustrations for Marah Ryan's book Flute of the Gods. Additionally, the collection contains a number of photographs of Curtis, his children, and portraits of various individuals including Theodore Roosevelt and actor Anna May Wong.

Biographical / Historical:
Edward Sherriff Curtis (1868-1952) was an American photographer famous for his photographs of the indigenous peoples of North America. His work was highly influential in shaping a sympathetic yet romantic view of cultures that he and many others believed to be "vanishing." Over the course of 30 years, Curtis visited more than 80 Native American communities and published his photographs and ethnographies in the twenty-volume North American Indian (NAI) (1907-1930).

Curtis was born in Whitewater, Wisconsin, to Ellen and Johnson Curtis in 1868. In about 1874, his family moved to a farm in Cordova, Minnesota. At a young age, Curtis built a camera, and it is possible that he may have worked in a Minneapolis photography studio for a time. In 1887, Curtis and his father moved West and settled on a plot near what is now Port Orchard, Washington, with the rest of the family joining them the following year. When Johnson Curtis died within a month of the family's arrival, 20-year-old Curtis became the head of the family.

In 1891, Curtis moved to Seattle and bought into a photo studio with Rasmus Rothi. Less than a year later, he and Thomas Guptill formed "Curtis and Guptill, Photographers and Photoengravers." The endeavor became a premier portrait studio for Seattle society and found success in photoengraving for many local publications. In 1892, Curtis married Clara Phillips (1874-1932) and in 1893 their son Harold was born (1893-1988), followed by Elizabeth (Beth) (1896-1973), Florence (1899-1987) and Katherine (Billy) (1909-?). Around 1895, Curtis made his first photographs of local Native people, including the daughter of Duwamish chief Seattle: Kickisomlo or "Princess Angeline." Curtis submitted a series of his Native American photographs to the National Photographic Convention, and received an award in the category of "genre studies" for Homeward (later published in volume 9 of the NAI). In 1896, the entire Curtis family moved to Seattle, which included Curtis's mother, his siblings Eva and Asahel, Clara's sisters Susie and Nellie Phillips, and their cousin William Phillips. Most of the household worked in Curtis's studio along with other employees. Curtis became sole proprietor of the studio in 1897, which remained a popular portrait studio but also sold his scenic landscapes and views of the Seattle Area. Curtis also sent his brother Asahel to Alaska and the Yukon to photograph the Klondike Gold Rush, and sold those views as well. Asahel went on to become a well-known photographer in his own right, primarily working in the American Northwest.

Curtis was an avid outdoorsman and joined the Mazamas Club after his first of many climbs of Mount Rainier. On a climb in 1898, Curtis evidently met a group of scientists, including C. Hart Merriam, George Bird Grinnell, and Gifford Pinchot, who had lost their way on the mountain, and led them to safety. This encounter led to an invitation from Merriam for Curtis to accompany a group of over 30 well-known scientists, naturalists, and artists as the official photographer on a maritime expedition to the Alaskan coast. Funded by railroad magnate Edward Harriman, the Harriman Alaska Expedition left Seattle in May of 1899, and returned at the end of July. Curtis made around 5000 photographs during the trip, including photographs of the indigenous peoples they met as well as views of mountains, glaciers, and other natural features. Many of the photographs appeared in the expedition's 14 published volumes of their findings.

In 1900, Curtis accompanied Grinnell to Montana for a Blackfoot Sundance. Here, Curtis made numerous photographs and became interested in the idea of a larger project to document the Native peoples of North America. Almost immediately upon returning from the Sundance, Curtis set off for the Southwest to photograph Puebloan communities. By 1904, Curtis had already held at least one exhibit of his "Indian pictures" and his project to "form a comprehensive and permanent record of all the important tribes of the United States and Alaska that still retain to a considerable degree their primitive customs and traditions" (General Introduction, the NAI) had taken shape and already received some press coverage. With his fieldwork now increasing his absences from home, Curtis hired Adolph Muhr, former assistant to Omaha photographer Frank Rinehart, to help manage the Seattle studio.

In 1904, Curtis was a winner in the Ladies Home Journal "Prettiest Children In America" portrait contest. His photograph of Marie Fischer was selected as one of 112 that would be published and Fischer was one of 12 children selected from the photographs who would have their portrait painted by Walter Russell. Russell and Curtis made an acquaintance while Russell was in Seattle to paint Fischer's portrait, and not long afterwards, Russell contacted Curtis to make photographic studies of Theodore Roosevelt's children for portraits he would paint. Curtis subsequently photographed the entire Roosevelt family, and developed a social connection with the President. Several important outcomes came of this new friendship, including Roosevelt eventually writing the foreword to the NAI, as well as making introductions to influential people.

Key among these introductions was one to wealthy financier John Pierpont Morgan, in 1906. After a brief meeting with Curtis during which he viewed several of Curtis's photographs of Native Americans, Morgan agreed to finance the fieldwork for the NAI project for five years, at $15,000.00 per year. It was up to Curtis to cover publishing and promotion costs, with the publication being sold as a subscription. In return, Morgan would receive 25 sets of the 20-volume publication. The ambitious publication plan outlined 20 volumes of ethnological text, each to be illustrated with 75 photogravure prints made from acid-etched copper plates. Each volume would be accompanied by a companion portfolio of 35 large photogravures. With high-quality papers and fine binding, a set would cost $3000.00. 500 sets were planned. Under Morgan, the North American Indian, Inc. formed as body to administer the monies. Also around this time, Frederick Webb Hodge, Director of the Smithsonian Institution's Bureau of American Ethnology, agreed to edit the publications.

Curtis then began more systematic fieldwork, accompanied by a team of research assistants and Native interpreters. In 1906, Curtis hired William E. Myers, a former journalist, as a field assistant and stenographer. Over the years, Myers became the lead researcher on the project, making enormous contributions in collecting data and possibly doing the bulk of the writing for the first 18 volumes. Upon meeting a new community, Curtis and his team would work on gathering data dealing with all aspects of the community's life, including language, social and political organization, religion, food ways, measures and values, and many other topics. (See box 2 folder 1 in this collection for Curtis's list of topics.) Curtis and his assistants, especially Myers, brought books and papers to the field relating to the tribes they were currently concerned with, and often wrote from the field to anthropologists at the Bureau of American Ethnology and other institutions for information or publications. In addition to fieldnotes and photographs, the team also employed sound recording equipment, making thousands of recordings on wax cylinders. Curtis also often brought a motion picture camera, although few of his films have survived.

The first volume of the NAI was published towards the end of 1907. Already, Curtis was encountering difficulty in finding subscribers to the publication despite great praise in the press and among those who could afford the volumes. Curtis spent progressively more of his time outside the field season promoting the project through lectures and in 1911, presenting his "Picture Musicale"—a lecture illustrated with lantern slides and accompanied by an original musical score—in major cities. After the initial five funded years, only eight of the twenty volumes had been completed. However, Morgan agreed to continue support for the fieldwork and publication continued.

Starting in 1910, Curtis and his team worked among the Kwakwaka'wakw First Nation on Vancouver Island, and in 1913 began to develop a documentary film project featuring the community in Alert Bay. In 1914, Curtis produced the feature-length film, In the Land of the Headhunters. The film showcased an all-indigenous cast and included an original musical score. Screened in New York and Seattle, it received high praise. However after this initial success, it did not receive the attention Curtis had hoped for, and resulted in financial loss.

Meanwhile, Curtis's prolonged absences from home had taken a toll on his marriage and in 1919 Clara and Edward divorced. The Seattle studio was awarded to Clara, and Curtis moved to Los Angeles, opening a photography studio with his daughter Beth and her husband Manford "Mag" Magnuson. Daughters Florence and Katherine came to Los Angeles sometime later. Curtis continued with fieldwork and promotion of the project, and in 1922 volume 12 of the NAI was published. Also in 1922, Curtis was accompanied during the field season in California by his daughter Florence Curtis Graybill, the first time a family member had gone to the field with him since the Curtis children were very small.

Curtis continued to push the project and publications along, yet never without financial struggle and he picked up work in Hollywood as both a still and motion picture photographer. John Pierpont Morgan, Jr., continued to provide funding for the fieldwork in memory of his father, but with the various financial upsets of the 1910s and 1920s, Curtis had a difficult time getting subscribers on board. In 1926, Myers, feeling the strain, regretfully resigned after the completion of volume 18. Anthropologist Frank Speck recommended Stewart Eastwood, a recent graduate from the University of Pennsylvania, to replace Myers as ethnologist for the final two volumes.

In 1927, Curtis and his team, along with his daughter Beth Curtis Magnuson, headed north from Seattle to Alaska and Canada on a final field season. Harsh weather and a hip injury made the trip difficult for Curtis, but he was very satisfied with the season's work. The party returned to Seattle, and upon arrival Curtis was arrested for unpaid alimony. He returned exhausted to Los Angeles, and in 1930 the final two volumes of NAI were published without fanfare. Curtis spent the next two years recovering from physical and mental exhaustion. Beth and Mag continued to run the Curtis studio in LA, but for the most part, Curtis had set down his camera for good. With the NAI behind him and his health recovered, Curtis pursued various interests and employment; he continued to do some work in Hollywood, including working on The Plainsman, starring Gary Cooper.

In 1933 Curtis was publicly criticized by John Collier, the Commissioner for Indian Affairs for some of the statements he had made on certain Pueblo ceremonies in the NAI volume 16, published in 1924. In September of 1934 Curtis received a letter from Harold Ickes, Secretary of the Interior regarding the claims published in volume 16, demanding a printed apology to be distributed among the text of the book as well as removal of the offending text from any undistributed copies of the publication. Curtis spent months writing and compiling supporting documentation in his defense, which he submitted to Ickes in January 1935. Also in 1935, the Morgan estate liquidated the North American Indian, Inc. and sold the remaining sets of the NAI volumes and unbound pages, photogravures, and copper printing plates along with the rights to the material to Boston bookseller Charles Lauriat for $1000.00.

Curtis's interest in gold prospecting took a front seat in the mid-1930s. While he scouted for potentially profitable mines in Northern California, his friend Ted Shell and possibly his son Harold sought investors. However, nothing ever fully panned out, though Curtis did design and build a concentrator for separating fine gold from placer tailings. He later sold the patent for ten dollars. Eventually, Curtis settled down on a farm outside Los Angeles, moving later to live with Beth and Mag, where he stayed until his death. In the mid to late 1940s Curtis began to write his memoirs. His daughter Florence visited him regularly and typed as Curtis dictated his recollections, and at some point he completed a draft of a memoir titled "As it Was." He also went through his papers and annotated or tucked notes among the correspondence and other material giving a brief explanation of the item or its context. Curtis died at home in 1952.

Prior to his death, Curtis had been out of the public eye for some years, and the NAI had slipped into relative obscurity. The Curtis studio in Los Angeles continued to sell Curtis's Native American photographs, and Florence gave occasional talks on her father, but it wasn't until the early 1970s that Curtis's work saw a renewed interest. This renaissance took place largely in the art photography market, but Curtis's biography and the NAI were also getting treatment in publications. Florence Curtis Graybill partnered with Victor Boesen to produce two narrative histories of Curtis and his work, and these were followed by many others. Florence continued to publish short works on her father for many years, and stayed in touch with numerous people involved in projects both scholarly and commercial that related to Curtis's work.

Biographical / Historical:
Photographs cover Edison's later life, beginning in his early 50's and continuing until his death in 1931 at age 84. Edison with an electric car: the car is a 1914 Detroit Electric Brougham model 47, serial number 5426. It was shipped December 19, 1913 to East Orange New Jersey, with an Edison Battery but with no motor (very unusual) (according to Galen Handy, 2/09/07; see

Dr. Bernard Finn, Curator of Electricity, National Museum of American History organized a traveling exhibition based on these and other photographs (most supplied by the Edison National Historic Site), "Edison After the Electric Light: The Challenge of Success," in 1986; it was circulated by the Association of Science-Technology Centers. In 1994 a revised version of the exhibition was prepared (again curated by Dr. Finn) for display in the National Museum of American History basement photography gallery; it was retitled "Edison After Forty: The Challenge of Success." In 1996, copies of the exhibit were given to museums in Japan, India, Yugoslavia, and China for circulation in those countries. Another version of this compilation had been published as "Thomas Alva Edison After Forty: The Challenge of Success in USA Today, July 1994, pp. 84-92.
One of the most famous of all Americans in any walk of life, Thomas Alva Edison hardly needs an introduction. He was the quintessential "genius" who invented or perfected a variety of electrical and technological devices which are still fundamental features of everyday life, not only in the United States, but around the world. Many of his or his companies' "inventions," of course, built on the pioneering work of others. Another Archives Center collection, the Gordon Hendricks Collection, includes the efforts of one scholar to debunk or minimize Edison's personal role in the development of motion picture cameras and projectors.

Edison was born in Milan, Ohio, February 11, 1847, and died October 18, 1931 at 84 years of age. His Edison Electric Light Company was the predecessor of the General Electric Co. While operating this company, and later working at laboratories in Menlo Park and West Orange, New Jersey, he was credited with patents for over one thousand inventions. A bibliography follows.
