Carl George Dietsch (1900-1978) was an electrical engineer who specialized in shortwave radio transmitters. He supervised the construction of radio stations for the Radio Corporation of America (RCA) and the National Broadcasting Company (NBC) from the 1930s to the 1960s, including locations in Brazil, Argentina, the Philippines, Japan, and Morocco. This collection consists of materials relating to Dietsch’s projects for RCA and NBC, particularly concerning the construction of a radio station in Tangier, Morocco, as well as the World War II Voice of America project in Dixon, California. The bulk of the collection material spans from the 1920s to the 1960s, with some later material from Dietsch’s time as a private engineering consultant. The collection includes correspondence, patent material, trade catalogs and publications, manuscript material, photographs and negatives, blueprints, diazotypes, audiovisual material, and drafting tools. This collection would be useful to researchers interested in shortwave radio station construction.

David Sarnoff (1891-1971) was the iconic leader of the Radio Corporation of America (RCA) for most of the company's history. For many years the only Jewish executive in the communications field, Sarnoff was highly influential in the development of radio and television. The focus of the David Sarnoff papers is the original David Sarnoff Collection assembled by Sarnoff to celebrate his career. However, the papers also include the extensive photographic, publicity, and administrative files created by his staff at RCA and a substantial audiovisual component.

For over fifty years the Radio Corporation of America (RCA) was one of the country's leading manufacturers and vendors of radios, phonographs, televisions, and a wide array of consumer and military electronics products. The Radio Corporation of America (RCA) and the Victor Talking Machine Company merged in 1929 becoming the RCA Victor Company in 1930. This merger allowed RCA to consolidate the research, engineering, manufacturing and sales of RCA products. This collection consists of negatives, a majority of which feature sound and television equipment manufactured by RCA. These images include phonographs, radios, radio-phonograph combinations, records, speakers, amplifiers, microphones, facsimile machines, televisions, equipment involved in the transmission and reception of television and radio waves, radio equipment created for use by government agencies and motion picture equipment.

Radio Corporation of America (RCA) was incorporated in 1919, entered the broadcasting field in July 1921 and shortly thereafter began to sell home broadcasting equipment manufactured by GE and Westinghouse. The collection consists of photographs and negatives relating to Radio Corporation of America (RCA), the Victor Talking Machine Company, which was purchased by RCA in 1929, and the RCA-Victor Division of Radio Corporation of America.

For over fifty years the Radio Corporation of America (RCA) was one of the country's leading manufacturers and vendors of radios, phonographs, televisions, and a wide array of consumer and military electronics products. The records of the RCA Corporation consist of three series: Secretary's files; B.L. Aldridge files; and the Camden Technical Library files. The collection is largely RCA technical reports, standards, engineering notebooks, manuals and miscellaneous publications. The Secretary's files document the formation of RCA. Aldridge's files deal almost entirely with the history of the Victor Talking Machine Company, RCA-Victor and the Camden Plant.
