The collection documents the life and career of Dr. Vladimir Zworykin, primary inventor of the commercial system of all-electronic television, supervisor of the development of the first commercial electron microscope, and one of the founders of the field of medical electronics, today better known as biomedical engineering. The material in the collection includes documents created from shortly after he joined the research division of the Radio Corporation of America (RCA) in 1929 through his formal retirement in 1954 as a vice president of RCA Laboratories (renamed the David Sarnoff Research Center in 1951), and from there through his active post-retirement career. The larger part of the collection consists of material from after 1954, and thus is richest in documenting Zworykins work in medical electronics and the work of the International Institute for Medical Electronics and Biological Engineering (IIMEBE), of which Zworykin was the founding chairman. The papers include publications and lectures spanning Zworykins career; reports and itineraries of trips from the 1930s through the 1970s; correspondence and letterbooks; research and development reports; patents; copies of the outgoing correspondence of John F. Davis, the director of the IIMEBE; photographs and book figures; personal records; and various other written and printed material. In addition, the David Sarnoff Library holds seven laboratory notebooks and one patent disclosure notebook created by Vladimir Zworykin, covering the years 1930 to 1942
