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-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.

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.
