Scope and Content:

The Alfonse A. Acampora papers record the evolution of important aspects of military and commercial communications systems. His research in the sciences of information technology and image projection for satellite communications and facsimile apparatus is particularly well documented. Most of the collection relates to his work at RCA Globcom.

Three of Acampora's lab notebooks (1973-1984) can be found in Record group 26.

Scope and Content:

The Charles B. Dieterich papers are composed of internal office correspondence, reports, schematics, notes, articles, and news clippings from Dieterich’s work on the improvement of digital storage, control systems, and sound for the VideoDisc project from 1978 to 1984.

Four of Dieterich's lab notebooks (1975-1987) can be found in Record group 26.

Scope and Content: This series describes Sperry's inventions and entrepeneurial activities in the two decades (1880-1900) when he was considered one of America's electrical pioneers. It documents his efforts to develop arc lighting systems, stationary power, mining machinery, and electric traction. The records describe the operation of the Sperry Electric Light, Motor, and Car Brake Company, which was founded in 1883 to set up electric power stations and manufacture component parts. These are fragmentary, but they do contain copies of Sperry's agreements with his financial backers and correspondence that traces his efforts to patent his inventions and secure customers.Records documenting Sperry's associations with the Electric Mining Machine Company and Independent Electric Company are far more complete. These files, which include incoming correspondence, letter books, sales books, and account books, trace Sperry's efforts to develop electric mine cars and undercuttting equipment. Sperry's letter books contain copies of a large number of reports he sent to the engineers at General Electric for analysis and comment. These letters show that Sperry was able to draw on the expertise of many of GE's young engineers who were, during the 1890s, graduating from engineering schools in relatively large numbers. These young engineers helped orient Sperry to the early twentieth-century world of professional engineering.The Chicago-Cleveland records document Sperry's relationship with the Link-Belt Company, which rented him space to manufacture his electric mine cars. The records also show that Link-Belt provided his company with both technical support and legal advice when he became embroiled in a number of patent infringement suits during the mid-1890s.The correspondence of the Goodman Manufacturing Company traces Sperry's continued involvement with coal-mining machine industry through the 1920s. These records show that Sperry continued to help make policy decisions and served as a consulting engineer long after he left Chicago.During the late 1890s, Sperry's primary interest was in street railways. His correspondence from this period describes his effort to develop and patent his electric governor and car brake. Correspondence with GE engineers show that Sperry's street car employed a mode of power transmission similar to that in his mine locomotive. The records describe Sperry's efforts to market his street cars as well as his...
