Descriptive Entry:
These records are the official minutes of the Board. They are compiled at the direction of the Secretary of the Smithsonian, who is also secretary to the Board, after approval by the Regents' Executive Committee and by the Regents themselves. The minutes are edited, not a verbatim account of proceedings. For reasons unknown, there are no manuscript minutes for the period from 1857 through 1890; and researchers must rely on printed minutes published in the Annual Report of the Smithsonian Institution instead. Minutes are transferred regularly from the Secretary's Office to the Archives. Minutes less than 15 years old are closed to researchers. Indexes exist for the period from 1907 to 1946 and can be useful.
Historical Note:
The Smithsonian Institution was created by authority of an Act of Congress approved August 10, 1846. The Act entrusted direction of the Smithsonian to a body called the Establishment, composed of the President; the Vice President; the Chief Justice of the United States; the secretaries of State, War, Navy, Interior, and Agriculture; the Attorney General; and the Postmaster General. In fact, however, the Establishment last met in 1877, and control of the Smithsonian has always been exercised by its Board of Regents. The membership of the Regents consists of the Vice President and the Chief Justice of the United States; three members each of the Senate and House of Representatives; two citizens of the District of Columbia; and seven citizens of the several states, no two from the same state. (Prior to 1970 the category of Citizen Regents not residents of Washington consisted of four members). By custom the Chief Justice is Chancellor. The office was at first held by the Vice President. However, when Millard Fillmore succeeded to the presidency on the death of Zachary Taylor in 1851, Chief Justice Roger Brooke Taney was chosen in his stead. The office has always been filled by the Chief Justice since that time.

The Regents of the Smithsonian have included distinguished Americans from many walks of life. Ex officio members (Vice President) have been: Spiro T. Agnew, Chester A. Arthur, Allen W. Barkley, John C. Breckenridge, George Bush, Schuyler Colfax, Calvin Coolidge, Charles Curtis, George M. Dallas, Charles G. Dawes, Charles W. Fairbanks, Millard Fillmore, Gerald R. Ford, John N.

Morton, Richard M. Nixon, Nelson A. Rockefeller, Theodore Roosevelt, James S. Sherman, Adlai E. Stevenson, Harry S. Truman, Henry A. Wallace, William A. Wheeler, Henry Wilson.

Ex officio members (Chief Justice) have been: Roger B. Taney, Salmon P. Chase, Nathan Clifford, Morrison R. Waite, Samuel F. Miller, Melville W. Fuller, Edward D. White, William Howard Taft, Charles Evans Hughes, Harlan F. Stone, Fred M. Vinson, Earl Warren, Warren E. Burger.

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-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.

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 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.

Historical Note:
The Consolidation Coal Company was started in 1864 to mine bituminous coal deposits in Maryland's Cumberland region. it expanded by acquiring other mine companies as well as rail and other transportation companies. It went into receivership in 1932. The Pittsburgh Coal Company, founded in 1900, took over the firm in 1945 and formed the Pittsburgh Consolidation Coal Company.

The Consolidation Coal Company (Maryland)

The Consolidation Coal Company was incorporated in Maryland on March 8, 1860, for the purpose of effecting a merger of a number of coal operators mining the Georges Creek basin in Allegany County, Maryland. Because of the Civil War, during which Confederate armies frequently blocked the region's only outlet to market, the company was not actually organized until April 19, 1864. Starting life as the dominant operator in this small but significant coal field, "Consol" rose to become the nation's top producer of bituminous coal.

The Georges Creek or Cumberland Coal Field, occupying part of the triangle of western Maryland, contained a high-quality, low-volatile bituminous steam coal which was also, thanks to the Potomac River, the coal of this type most accessible to Eastern markets. Coal had been mined in the region beginning in the 1700s, and the first coal company, the Maryland Mining Company, had been incorporated in 1828. However, large-scale development could not occur until the mid-1840s, after the Baltimore and Ohio Railroad reached Cumberland and provided reliable transportation. This also coincided with the development of ocean steam navigation and a rapid growth in the number of railroad locomotives and stationary steam engines. Cumberland coal was ideal for ship bunkering, and much of the output was shipped to New York Harbor. Naturally, New York capitalists and manufacturers played a leading role in developing the field. Lewis Howell's Maryland and New York Iron and Coal Company rolled the first solid U.S. railroad rail at its Mount Savage mill in 1844. The Consolidation Coal merger was put together by New Yorkers such as William H. Aspinwall, Erastus Corning, the Delanos and Roosevelts, and the Boston financier John Murray Forbes, who already had substantial investments in the region.

Upon its formation, the Consolidation Coal Company acquired the properties of the Ocean Steam Coal Company, the Frostburg Coal Company, and the Mount Savage Iron Company totaling about 11,000 acres. The last named company brought with it control of the Cumberland and Pennsylvania Railroad, which connected the mines to the Baltimore & Ohio and later the Pennsylvania and Western Maryland railroads. In 1870, Consol absorbed the Cumberland Coal and Iron Company of 1840, the next largest operator in the field, and gained an additional 7,000 acres. Further purchases from the Delano interests gave it over 80 percent of the entire Cumberland Field.

Soon after its hated rival, the Pennsylvania Railroad, gained access to the Cumberland Coal Field, the Baltimore and Ohio Railroad began purchasing large blocks of Consolidation Coal stock to protect its traffic base in 1875, eventually gaining a 52 percent interest. A B&O slate of directors was elected in February 1877, with Charles F. Mayer of Baltimore as president, and the company offices were moved from New York to Baltimore.

Until the turn of the century, Consolidation Coal's mining operations were confined to the small soft coal region of western Maryland. The company purchased the 12,000 acre Millholland coal tract near Morgantown, W.Va. in 1902 and acquired controlling interests in the Fairmont Coal Company of West Virginia and the Somerset Coal Company of Pennsylvania the following year. These acquisitions boosted Consolidation's annual production more than six-fold in only three years. The company purchased the 25,000 acre Stony Creek tract in Somerset County, Pa., in 1904. The Fairmont Coal Company purchase included a joint interest in the North Western Fuel Company, which owned and operated docks and coal distribution facilities in Wisconsin and Minnesota.

In 1906, the Interstate Commerce Commission held a formal investigation of rail ownership of coal companies, which resulted in the passage of the Hepburn Act and its "Commodities Clause," which prohibited railroads from dealing in the commodities they hauled. In anticipation of the new regulations, the Baltimore and Ohio Railroad sold its entire holdings of Consolidation stock to a Baltimore syndicate headed by Consol president Clarence W. Watson, J. H. Wheelwright and H. Crawford on April 26, 1906. At the time of the B&O's divestiture, the aggregate annual output of Consolidation's mines totaled more than 10 million tons and the company controlled more than 200,000 acres. The John D. Rockefeller interests began purchasing Consol securities in 1915, eventually securing a controlling interest. The company's offices were returned to New York City in May 1921.

After the B&O divestiture, Consol began expanding into the Southern Appalachian coal fields, which were just being opened by railroads on a large scale. The mines in this region yielded a low volatile coal that provided an ideal fuel source for stationary steam engines, ships, and locomotives. Of equal importance, operators in the remote mountains had been able to resist unionization and thus achieve lower operating costs, while all of Consol's previous holdings had been in the so-called "Central Competitive Field" to the north, which had been unionized in the 1890s. Consolidation Coal purchased 30,000 acres in the Millers Creek Field of Eastern Kentucky in 1909 and 100,000 acres in the Elkhorn Field the next year. In February 1922, Consol secured a long term lease and option on the Carter Coal Company, whose 37,000 acres straddled the borders of Virginia, West Virginia and Kentucky. In 1925, Consol became the nation's largest producer of bituminous coal, excluding the captive mines of the steel companies.

During the Great Depression, Consolidation Coal experienced serious financial difficulties and was forced into receivership on June 2, 1932. The Rockefellers liquidated their holdings at a loss, and the Carter Coal Company was returned to the Carter heirs in 1933. Consol was reorganized and reincorporated in Delaware as the Consolidation Coal Company, Inc. on November 1, 1935, and was able to retain its position as one of the nation's top coal producers. Eventually, stock control passed into the hands of the M.A. Hanna Company group of Cleveland, dealers in coal and iron ore. Although production reached record levels during the Second World War, management feared a recurrence of the collapse that had followed World War I. It also faced the prospect of increased competition from oil and natural gas and the loss of traditional markets such as home heating and locomotive fuel. As a result Consol opened negotiations with another large producer, the Pittsburgh Coal Company, which was the dominant operator in the Pittsburgh District.

The Pittsburgh Coal Company

The Pittsburgh Coal Company was a product of the great industrial merger movement of the late 1890s. In 1899, two large mergers were effected in the Pittsburgh District.

The Monongahela River Consolidated Coal and Coke Company was incorporated in Pennsylvania on October 1, 1899 to merge the properties of over 90 small firms operating mines along the Monongahela River south of Pittsburgh. Some of these operations dated to the early 1800s, and all of them shipped coal down the Ohio-Mississippi River system by barge from close to the mine mouth, or later by the railroads built along the river banks. The combination controlled 40,000 acres of coal land, 100 steam towboats, 4,000 barges, and facilities for handling coal at Cincinnati, Louisville, Vicksburg, Memphis, Baton Rouge and New Orleans.

The Pittsburgh Coal Company was incorporated in New Jersey as a holding company on September 1, 1899 and acquired the properties of over 80 operators located in the areas back from the river on both sides of the Monongahela south of Pittsburgh. The combination was engineered by some of the most prominent Pittsburgh industrialists, including Andrew W. Mellon, Henry W. Oliver, and Henry Clay Frick. It controlled over 80,000 acres and six collector railroads, the longest of which was the Montour Railroad. Most of its output was shipped by rail, with a large share being transferred to ships on the Great Lakes for distribution throughout the industrial Midwest. The company owned coal docks and yards at Chicago, Cleveland, Duluth, West Superior, Sault Ste. Marie, Ashtabula, Fairport and Thornburg. Subsequently, the company expanded in southwestern Pennsylvania and the Hocking Valley of Ohio through the lease of the Shaw Coal Company in 1901 and the purchase of the Midland Coal Company in 1903. Most of the properties were vested in a separate Pittsburgh Coal Company, an operating company incorporated in Pennsylvania.

Unlike the Consolidation Coal Company, which had grown by gradual accretion, the Pittsburgh Coal Company had been created in a single stroke. As with many mergers of the period, its capitalization probably contained a high percentage of "water" in anticipation of profits from future growth. Unfortunately, the years after the merger saw explosive growth in the coal fields of Southern Appalachia instead. Although farther from major consuming centers, they enjoyed several advantages. The coal itself was superior, low-volatile with higher BTU content and altogether cleaner than the high-volatile coals of Ohio and the Pittsburgh District. As already noted, the southern mines were also non-union. With the inroads of Southern Appalachian coal, the Pittsburgh Coal Company continuously lost ground in the crucial Lake and western markets from 1900 to 1915. The company's capitalization proved unwieldy in the unsettled economic conditions following the Panic of 1907. A reorganization plan was devised under which a new Pittsburgh Coal Company was incorporated in Pennsylvania on January 12, 1916 by merging the old Pittsburgh Coal Company of Pennsylvania and the Monongahela River Consolidated Coal and Coke Company. The old holding company was then liquidated and the stock of the new operating company distributed to its stockholders. Dissension between the common and preferred stockholders delayed consummation of the plan until July 16, 1917.

The Pittsburgh Coal Company, which had all its operations in the Central Competitive Field, had a much more difficult time than Consolidation in breaking the 1923 Jacksonville Agreement with the United Mine Workers in 1925-1927 and reverting to non-union status. The three-year struggle ended the company's ability to pay dividends. Pittsburgh Coal survived the Depression without receivership but with ever-increasing arrearages on its preferred stock. By the end of World War II, its managers were just as eager as those at Consol to attempt greater economies through merger. The Pittsburgh Coal Company and the Consolidation Coal Company merged on November 23, 1945, with exchange ratios of 65 to 35 percent. Pittsburgh Coal Company, the surviving partner, changed its name to the Pittsburgh Consolidation Coal Company.

The Pittsburgh Consolidation Coal Company

After the merger, the M.A. Hanna Company interests of Cleveland became the dominant factor in Pitt-Consol's affairs. Hanna had transferred its pre-merger Consol stock to its subsidiary Bessemer Coal & Coke Corporation in 1943. This led to a restructuring whereby Pitt-Consol acquired Hanna's share of the North Western-Hanna Fuel Company in April 1946 and the Hanna coal properties in eastern Ohio on June 16, 1946 These included large reserves of strippable coal that accounted for about 20 percent of the state's production. Pitt-Consol later acquired Hanna's holdings of coal land in Harrison, Belmont and Jefferson Counties, Ohio, on December 30, 1949. It purchased the New York Central Railroad's 51 percent interest in the Jefferson Coal Company, giving it full control, in 1952 and merged it into the Hanna Coal Company Division.

Pitt-Consol sold its last major railroads, the Montour Railroad and the Youngstown & Southern Railway to the Pennsylvania Railroad and the Pittsburgh & Lake Erie Railroad on December 31, 1946. The Northwestern Coal Railway had been sold to the Great Northern system, and the Cumberland & Pennsylvania Railroad had been sold to the Western Maryland Railway in May 1944.

In addition, a new Research and Development Division was created to fund projects aimed at developing more efficient production methods, new outlets for coal consumption, coal-based synthetic fuels and chemical byproducts. A new coal gasification plant opened at Library, Pa., in November 1948, and the company began the manufacture of a smokeless fuel briquette under the trademark "Disco" at Imperial, Pa., in 1949. An experimental coal slurry pipeline was built in Ohio in 1952.

During the 1950s and early 1960s, Pitt-Consol made many changes in its coal holdings, selling high-cost or less desirable properties, diversifying its reserves across many different coal fields, rationalizing property lines to permit large mechanized underground or strip mines and forming joint ventures with steel companies to secure guaranteed customers. Pitt-Consol acquired the Jamison Coal and Coke Company in 1954 and the Pocahontas Fuel Company, Incorporated, a large producer of low-volatile Southern Appalachian coal, in 1956. In the latter year, it sold its Elkhorn Field properties to the Bethlehem Steel Corporation. As Pittsburgh District operations became less central, the corporate name was changed back to Consolidation Coal Company in April 1958.

The Consolidation Coal Company, CONOCO and CONSOL Energy, Inc.:

Consol continued to expand into the early 1960s. On April 30, 1962, it absorbed the Truax-Traer Coal Company of Illinois. Truax-Traer also mined lignite in North Dakota, a low-grade but low-sulfur coal that was taking a greater share of the power generation market as environmental laws placed greater restrictions on high-sulfur coal from the Central Competitive Field. The following year Consol acquired the Crozer Coal and Land Company and the Page Coal and Coke Company, owners of additional reserves of low-volatile, low-sulfur steam coal in southern West Virginia.

In 1966, just two years after the company marked its centennial, Consolidation Coal was acquired by the Continental Oil Company (Conoco). This was part of a general trend whereby U.S. oil companies extended their reach by acquiring coal reserves and large coal producers. In turn, Conoco was acquired by E.I. du Pont de Nemours & Company in 1981. This purchase was motivated by DuPont's desire to obtain better control of chemical feedstocks in an era of high oil prices. Consolidation Coal was not a major factor in the Conoco acquisition and did not really fit into DuPont's strategy, especially after coal and oil prices declined. As a result, it was quickly sold off when DuPont was restructured a decade later. In 1991, a new holding company CONSOL Engery, Inc. was incorporated as a joint venture of DuPont Energy Company and the German energy conglomerate Rheinisch-Westfalisches Elektrizitatswerk A.G., through its wholly owned subsidiaries Rheinbraun A.G. and Rheinbraun U.S.A. GmbH. Consolidation Coal Company became a wholly-owned subsidiary of CONSOL Energy, Inc. DuPont eventually sold most of its half interest, so that by 1998, Rheinbraun affiliates owned 94% of CONSOL Energy stock, while DuPont Energy retained only 6%. CONSOL Energy purchased the entire stock of the Rochester & Pittsburgh Coal Company on September 22, 1998. CONSOL Energy stock began trading on the New York Stock Exchange under the symbol "CNX" in 1999, with an initial public offering of more than 20 million shares.

CONSOL Energy produced more than 74 million tons of coal in 1999, accounting for approximately 7% of domestic production. The company currently operates 22 mining complexes, primarily east of the Mississippi River.

The Consolidation Coal Company (Consol) was created by the merger of several small operators mining the Georges Creek coal basin in Allegany County, Maryland. The company expanded rapidly in the early twentieth century through the purchase of substantial tracts in the coal fields of Pennsylvania, West Virginia, and Kentucky as well as docks and distribution facilities in the Great Lakes region. By 1927, Consol was the nation's largest producer of bituminous coal. Following a merger with the Pittsburgh Coal Company in 1945, the company pursued a policy of acquiring companies which afforded opportunities for greater diversification while selling off unprofitable lines. In addition, a new research and development division was created to fund projects aimed at developing more efficient production methods and new outlets for coal consumption. The records of the Consolidation Coal Company and its affiliated companies are arranged in seven series. Minute books and contract files provide the most comprehensive documentation in this collection.
