James R. Matey papers, 1974-2003

 Series
Accession: 2464-09Identifier: 2464-09-22.
Scope and Content:

James R. Matey preserved documents which help to explain his work in developing instruments used to control and manipulate data and materials, tools to measure the impact of materials introduced in his experiments, and microscopes which became useful to describe and improve various products. His work is reflected clearly by the number of patents he received, and by the many records which document his work with microscopy, picture tubes, and VideoDiscs.

The Matey papers includes photographs, overhead transparencies, 35mm slides, videocassettes, and one video disc. These depict work done with scanning capacitance microscopy (SCaM) including micrographs of silicone on sapphire, video discs, and graphs and diagrams used in a presentation on scanning capacitance microscopy.

Twenty-nine of Matey's lab notebooks (1977-1991) can be found in Record group 26.

Dates: 1974-2003

Philip M. Heyman papers, 1980-2002

 Series
Accession: 2464-09Identifier: 2464-09-18.
Scope and Content:

The documents in the Philip M. Heyman papers describe the development with Thomson Consumer Electronics of a picture tube named Eagle, which was intended to prevent noise from vibrations in tubes used for generating audio/visual sound and display. Scientists named the noise microphonics. In addition, the papers explain the work of Heyman and his team to develop flat screen televisions, as well as describe the complexity of flat screen TV.

Seventeen of Heyman's lab notebooks (1963-1982) can be found in Record group 26.

Dates: 1980-2002

Products, 1912-1965

 Series
Accession: 1986-273Identifier: 1986-273-III.
Scope and Contents: Products series is divided into eleven subseries: Aeronautical Systems; Air armament; Aircraft sights and turrets; Army Fire Control (AFC), Bomber Navigation Systems (BNS); Marine systems; Microwave and electronic equipment; Navy Fire Control (NFC) and Navy systems; Radio and electronics; Surface armament; and Searchlights.Throughout the subseries many folders are titled with “AN/” followed by a series of letters and numbers. The United States military use letter combinations to designate electronic and communications equipment. This designation system is called the "Joint Communications-Electronics Nomenclature System" or “AN” for short (Army-Navy). All designations have the “AN/” prefix followed by three letters, a number, and potentially followed by another single letter and a version. The letters in different positions signify the installation, equipment type, and purpose. See the Wikipedia entry for Joint Communications-Electronics Nomenclature System for the full explanation of the letters in the system. Aeronautical systems subseries are images of parts and components for aircraft related to autopilots, gyros, and navigation. There are many folders containing images of products from various Sperry departments. Departments were assigned numbers, however, there is no key within the collection that explains what the numbers mean or what the name of the department was. The images date from 1912 to 1918 and from 1926 to 1964. The films in this subseries are primarily of flight tests, there are a few films not produced by Sperry that show old versus new methods of manufacturing or installing different parts, and there is a three part series about weighted guidelines.Air Armament subseries are images of components primarily related to radar. There are also images of parts, components and the production of aircraft bombers Hustler B-58 and Tempo I, and the air-to-air guided missile, the Sparrow. The images date from 1948 to 1962. There is one film showing various tests of targeting by air.Aircraft sights and turrets subseries contains images of bombsights, gunsights and turrets. The images date from 1916 to 1947. There are many films showing tests of gunsights, particularly the Airborne Gunlaying System (AGL). There are also films showing various turret experiments, specifically with the Central Station...

Vladimir K. Zworykin papers, 1908-1981

 Series
Accession: 2464-09Identifier: 2464-09-6.-I.
Scope and Content:

The collection includes Dr. Vladimir K. Zworykin's records he created shortly after joining the research division of Radio Corporation of America (RCA) in 1929 through his formal retirement in 1954 as a vice president of RCA Laboratories, and from there through his active post-retirement career. While Zworykin is best known for his work on television during the 1920s and 1930s, the larger part of the collection consists of material documenting Zworykin’s work in medical electronics research and chairmanship of the International Institute for Medical Electronics and Biological Engineering.

Zworykin’s papers are composed of his publications, lectures, and other writings; patents and awards conferred; correspondence with domestic and international colleagues related to the span of his research from television to medical technologies; and research materials.

Photographs document Zworykin's career at RCA including work on kinescopes, the electron microscope, television, and other equipment. Audio and video materials contain a documentary of Zworykin's life and interviews about Zworykin with other RCA employees.

Ten of Zworykin's patent disclosure books (1930-1943) can be found in Record group 26.
