When did James West invent the microphone?
1962
West and his research partner, Gerhard Sessler, invented the microphone in the 1962 while working at Bell Laboratories. What would become a staple in everyday life began as an obsessive curiosity.
Why did James West create the microphone?
West’s Microphone Their goal was to develop a compact, sensitive microphone that wouldn’t cost a fortune to produce. They completed development of their electret microphone in 1962 – it worked on the basis of the electret transducers they had developed – and they began production of the device in 1969.
What was James E West famous for?
James West is a professor of electrical and computer engineering and mechanical engineering. He is known worldwide as the co-inventor of the foil electret microphone.
What black man invented the microphone?
James Edward West
Ninety percent of microphones used today are based on the ingenuity of James Edward West, an African-American inventor born in 1931 in Prince Edwards County, VA. If you’ve ever talked on the telephone, you’ve probably used his invention.
Who inspired James West?
West has one brother, Nathaniel. West’s interest in electricity resulted from his work with his cousin to put electrical wiring into homes in rural Virginia when he was twelve years old.
Who invented the first microphone?

Who discovered microphone?
When was the first microphone invented?
1877
This drumlike device is a carbon-button microphone, patented by Emile Berliner in 1877. It was one of the first ever created and by far the most usable. Berliner is credited with inventing the carbon-button microphone in 1876.
Who invented the microphone 1877?
Emile Berliner
In 1877 Emile Berliner filed a patent for a microphone — the carbon microphone. Alexander Bell, who only a year before had invented the telephone, recognized the practical importance of Berliner’s technology. So he bought the patent for $50 thousand — a huge sum at the time.
Who invented the piezoelectric microphone?
| Year | Microphone | Inventor(s) |
|---|---|---|
| 1886 | Carbon-Button Microphone | Thomas Edison (US) |
| 1916 | Condenser Microphone | E.C. Wente at Western Electric (US) |
| 1917 | Piezoelectric Microphone | Paul Langevin (France) |
| 1920 | Electret Microphone | Yoguchi (Japan) |
Who invented mics?
Alexander Graham Bell patented the first microphone in 1876. His microphone consisted of a wire which conducted electrical direct current (DC). Audio signals were generated and received by a moving armature transmitter and its receiver, and transmission was possible from both directions.
Who made first microphone?
When did James West invent the electret microphone?
In conjunction with Gerhard Sessler, West patented the electret microphone in 1964 while working at Bell Laboratories. West’s research in the early 1960s led to the development of the foil electret transducers for sound recording and voice communication that are used in 90 percent all microphones built today.
What kind of inventions did James West make?
During his career, West has received an array of accolades and honors as well as developing more than 250 patents on microphones and related discoveries involving polymer-foil electrets.
Who was the inventor of the foil microphone?
Born in Prince Edward County, Virginia, on February 10, 1931, James West attended Temple University before working for Bell Labs. Along with Gerhard M. Sessler, he developed the foil electret microphone, an inexpensive, compact device that is now used in 90 percent of all contemporary microphones.
What did James Edward Maceo West invent?
Along with Gerhard Sessler, West invented the foil electret microphone in 1962 while developing instruments for human hearing research. Compared to the previous condenser microphones, the electret microphone has higher capacitance and does not require a DC bias. West and Sessler optimized the mechanical and surface parameters of the system.
