The Lester L. Libby papers consist of files created and maintained by Lester Louis Libby (1916-2002) pertaining to his work in the technical field of sound engineering and the application of microwave frequency technologies in various industries including radio, television, and early electronics from the 1930s to the 1970s. Materials include Libby's resarch notebooks, work papers, diagrams and schematics, articles he authored, and patents received.

Lester Louis Libby was born at Hartford, Connecticut in 1914. He received the B.S. and M.S. degrees in electrical engineering from the Worcester Polytechnic Institute in 1935 and 1936, respectively. In 1934, Libby began his career in the radio engineering field when he became radio transmitter operator at radio station WTAG in Worcester, Massachusetts. Throughout the 1930s, Libby held positions at companies involved with pioneering research and technological developments in radio communications, including as a radio-tube design engineer for RCA Radiotron, and at the radio receiving-tube division of Tung-Sol Lamp Works. In 1941, Libby began working in research development and eventually became Chief Engineer for the Federal Telegraph Company, a company founded in Palo Alto, California that specialized in developing high-powered transmitters used for long distance radiotelegraph communication.
