James Edward Maceo West (born February 10, 1931) is an American inventor and acoustician. He holds over 250 foreign and U.S. patents for the production and design of microphones and techniques for creating polymer foil electrets.

Apr 2, 2014 · James West is a U.S. inventor and professor who, in 1962, developed the electret transducer technology later used in 90 percent of contemporary microphones.

James Edward West (May 16, 1876 – May 15, 1948) was a lawyer and an advocate of children's rights, who became the first professional Executive Secretary, soon renamed Chief Scout Executive, of the Boy Scouts of America (BSA), serving from 1911 to 1943.

Discover the story of James West, who co-invented the electret microphone, used in products ranging from recording equipment to phones and hearing aids.

Ninety percent of microphones used today are based on the ingenuity of Dr. James E. West, an African-American inventor who developed the mic in the 1960s.

James Edward West was born on February 10, 1931 in Prince Edward County, Virginia. He was an inquisitive young boy, fascinated with electronics and always ready to take things apart to discover how they worked. His curiosity almost got the better of him when he was eight years old and decided repair a broken radio.

James Edward West's research'in the early 1960s led to the development of foil-electret transducers for sound recording and voice communication that are used in 90% of all microphones built today and at the heart of most new telephones being manufactured.

James E. West, a research professor at Johns Hopkins University’s Whiting School of Engineering, is best known as the co-inventor of the foil-electret transducer, an inexpensive but highly sensitive device that revolutionized the sound industry and is now the basis of sound transmission in most cell phones, hearing aids, professional…

James Edward West, Ph.D., a Bell Laboratories Fellow at Lucent Technologies, is a renowned expert in acoustics. His pioneering work in the 1960s, with co-inventor Gerhard Sessler, led to the invention of the foil electret microphone. Today, 90% of the 2 billion microphones manufactured yearly are electret microphones.
