Which of the famous black inventors developed the electret microphone?

James Edward West

Ninety percent of microphones used today are based on the ingenuity of African American inventor James Edward West.

West and a colleague, Gerhard Sessler, developed the mic (officially known as the Electroacoustic Transducer Electret Microphone) while working for Bell Laboratories. They received a patent for the mic in 1962.

Throughout his 40-year career with Bell Labs, West obtained 47 U.S. patents and more than 200 foreign patents, making him one of the most prolific black inventors in history.
