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.

Administrative Information


Provenance

Company historian Frederick O. Barnum III salvaged this collection from the abandoned photo lab on the 4th floor of Building 10 of the RCA Camden Plant, after the plant had been vacated and abandoned by successor company Martin Marietta Corporation in April 1993.

Processing Notes

The negatives included a note from RCA’s Data Management-Photographic department stating: “Damaged negatives have been removed and destroyed. If requested and not in file, report as “destroyed -- unusable.” This note is dated 1980.

A card index was created by staff at RCA which identifies each image and often includes the following information: negative number, image description, subject, department, building, floor, associated names, and remarks. Not every index card includes all of the information listed above and not every negative is accounted for in the card index. The card index is handwritten and was transcribed by volunteers: Marlene Knowles, Susan Cherrin, and Kathleen O’Hara under the supervision of Audiovisual Reference Archivist, Lynsey Sczechowicz.

The negatives were identified using the index and rehoused according to archival best practices by interns Becky Koch and Melanie Grear.

The Historical note was written by Christopher Baer with a revision by AVD Staff.

The finding aid was completed by Laurie Sather, Angela Schad, and Kevin Martin.

Conservation Note

A portion of the negatives have badly degraded over time and may require conservation prior to research use. These negatives have been separated from the rest of the collection and appear in the finding aid inventory with a note that says: “REQUIRES CONSERVATION.” Please contact the archivist to inquire about these negatives in advance of your research visit.

Historical Note

For over fifty years, the Radio Corporation of America 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 company was incorporated in Delaware on October 17, 1919, and changed its name to RCA Corporation on May 9, 1969. Through subsidiaries, it operated the country’s first radiotelegraph, radiotelephone and radio facsimile systems, as well as its pioneer radio and television networks. The company will always be identified with David Sarnoff (1891-1971), who began working for a predecessor company as an office boy in 1906, became vice president in 1922, president in 1930, and served as chairman from 1947 to 1970. Sarnoff was one of the first to grasp the full potential of radio and television and imparted to the company its reputation for research and innovation.
