John H. Reisner, Jr. papers, 1924-1995

Accession: 2464-09Identifier: 2464-09-13.-III.
Scope and Content:

The collection primarily consists of correspondence, memoranda, and reports documenting Reisner's research in electron microscopy and the RCA VideoDisc. Reisner's personal life and his service to the church and community is also described via personal correspondence and meeting notes.

Photographs and slides document the different types of electron microscopes including Electron Emission Microscope, Reflection Electron Microscope, as well as EM-3 and EM-75 Microscopes. They also document the use of the microscope and how it is impacted by diffraction, optical reconstruction apparatus, contamination as a function of electrical charge density, carbon film thickness impact on transmission, and the impact of temperature on level of contamination. Other images show substances including diseases (polio virus, influenza virus, necrosis virus, and tumors) everyday objects (soap), and chemical elements (lead oxide). There are also images of Trichocysts from Paramecium and Paramyosin Fibril stain with Phosphotungstic Acid.

One of Reisner's lab notebooks (1979-1982) can be found in Record group 26.

Dates: 1924-1995

Vladimir K. Zworykin papers, 1908-1981

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.

Dates: 1908-1981
