Benjamin B. Bauer (originally Baumzweiger) (1913–1979) was a Russian Empire-born American acoustic engineer, who worked for the Shure microphone company and produced over 100 patents.[1] His early work in acoustics lead to the development of modern sound technology via the Uniphase Electrical Principle [citation needed]. This principle is the source of the Unidyne Microphone's name and functionality.
