Carl G. Dietsch papers
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.
Frederick O. Barnum III collection of RCA Victor Company negatives
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.
