Without James West, it would be impossible to make a modern phone call, record a voice memo, sing karaoke, or use a hearing aid to amplify a conversation. James West deserves praise if you’ve just used your cell phone or listened to a piece of wonderful music. James Edward Maceo West is an American inventor and acoustician.

With his work in the physics field since the 1960s, he is considered one of the top minds in the innovation business and ranks among the greatest American inventors. His passion for electricity changed how individuals hear and transfer sound while engaging in daily activities, whether on a large or small scale. Here are the top 20 facts about James E. West.

1. West was born on February 10, 1931, in Virginia

The eldest of two children West was born on February 10, 1931, to Samuel Edward and Matilda West in Farmville, Prince Edward County, Virginia. Because African-Americans could not be admitted to the nearby hospital, he was born at the home of his maternal grandparents. His father held positions on the Baltimore and Ohio Railroad as a Pullman porter, an insurance salesman, and a funeral home owner at various times.

His mother was a teacher who worked at Langley Air Force Base during World War II. After losing her job as a result of her membership in the NAACP, she eventually joined the group of African Americans who worked as human computers for NASA at Langley Research Center otherwise known as the “Hidden Figures.”

2. He attended Temple University to pursue Physics

His parents sent him to Phenix High School in Hampton, Virginia for better opportunities after he finished school in Farmville; he was supposed to attend Robert Russa Moton High School. He attended Hampton University on a pre-medical track after high school before being drafted into the U.S. Army during the Korean War, where he was wounded and awarded the Purple Heart. He then turned into a pacifist and enrolled at Temple University to study physics.

He got turned away from study groups because of his race and was only invited to join them after resolving the trickiest group problems by himself. He read Leon Trotsky’s writings and went to Black Panther gatherings while attending Temple. He finished his bachelor’s and master’s degrees in Physics at Temple University by 1957, but he did not officially graduate since he returned to Bell Laboratories in November of that year to continue working.

3. He did a summer internship with Bell Laboratories

During his summer internship at Bell Laboratories as a graduate student, he started inventing the Electret microphone. As a Bell Labs intern, West was entrusted with assisting a team of researchers as they looked into the interaural time difference or the difference in the time a sound takes to reach each ear.

After spending some time at the library, West was able to build a headphone that produced a loud, clear sound since the group was unable to discover a microphone that would make such a sound. After about six months or so, the device’s sound started to deteriorate, and West returned from Temple University to work on it again at Bell Labs.

4. West co-invented the foil electret microphone in 1962

In 1962, West and Gerhard Sessler devised the foil electret microphone while working on devices for studies on human hearing at the Bell laboratory. The electret microphone has a larger capacitance than the preceding condenser microphones and doesn’t need a DC bias. The mechanical and surface properties of the system were tuned by West and Sessler.

The foil-electret concept is the foundation for about 90% of the more than two billion microphones produced each year. These microphones are used in commonplace products like cellphones, camcorders, hearing aids, baby monitors, and audio recording devices, among others.

5. He holds over 250 patents for Microphones production and design

During his 40-year career with Bell Laboratories, where he worked as an acoustical scientist, he obtained more than 250 foreign and American patents for the manufacture and design of microphones as well as methods for producing polymer foil electrets. Additionally, he has written or contributed to more than 150 technical publications as well as several books on materials science, solid-state physics, and acoustics.

6. West retired from Bell in 2001

After an illustrious 40-year career at Bell Laboratories, where he was awarded the company’s highest honour by being designated a Bell Laboratories Fellow, West resigned from Lucent Technologies in 2001. Located in Murray Hill, New Jersey, Lucent Technologies, Inc. was a multinational American manufacturer of telecom equipment.

Western Electric and Bell Labs were part of the former AT&T Technologies business segment of AT&T Corporation, which was sold off on September 30, 1996, giving rise to it.

7. West is a research professor at Johns Hopkins University
