Abstract: Herbert Belar (1901-1997) was an inventor and research scientist in the field of acoustical engineering at the RCA David Sarnoff Research Center in Princeton, New Jersey for thirty-eight years. He developed "hi-fi" recording, the phonetic typewriter, and the electronic music synthesizer. This small collection of Herbert Belar papers reflects the professional daily work of an acoustical engineer from the 1930s through the 1960s. There is significant documentation on the phonetic typewriter, the 200 speech communication system, the music composing machine, and the electronic music synthesizer. Notable inclusions are information related to the development of "hi-fi," film motion pictures sound recording, and phonographic records recording. There is only one file that discusses Belar's work at the MAD Laboratory.
