Inventor James West was born in 1931 in Virginia. As a child, he spent lots of time studying how things worked and enjoyed taking apart small machines. "If I had some tools, any small machines that could be opened were in danger," West said. "I had a strong desire to know what was inside. "
After an accident with a radio, West paid special attention to electricity. But his parents were concerned about the future job for an African-American scientist. They preferred him to become a doctor. However, West headed to Temple University in 1953 to study physics. Because of his school performance in physics, he managed to get training during the summer at Nokia Bell Labs, a world-known American industrial research and scientific development company. He received a college degree in physics in 1957, and upon graduation, he became a worker at Nokia Bell Labs.
In 1960, while at Bell, West teamed up with scientist Sessler to develop a less expensive, more powerful and smaller microphone (麦克风), In 1962, they finished the development on the product. Their invention became the industry standard. And even today, 90 percent of microphones — for example, found in telephones, tape recorders, baby monitors and hearing aids — are based on their technology.
West was chosen as Inventor of the Year by the state of New Jersey and president of the Acoustical Society of America. And both West and Sessler were chosen into the National Inventors Hall of Fame.
West left Bell in 2001. After some interviews with several universities, he chose the Johns Hopkins University and became a research professor at its Whiting School of Engineering. "I discovered that Johns Hopkins was a lot like Bell Labs, where the doors were always open and we were free to work with researchers in other areas," he said. "I like the fact that I won't be locked into one small closed room here. "
