Demonstrates First TransistorJune 30, 1948 • William Shockley, John Bardeen, and Walter Brattain demonstrated the first transistor to a press conference in New York at the Bell Laboratories. • Prior to the transistor there was the vacuum tube, which was fragile and required tons of power • The Transistor is a semiconductor device that is used to amplify and switch electronic signals and electrical power • Composed of semiconductor material with terminals for connection to an electrical circuit. • A current applied to one pair of terminals changes the current through another pair of transistors • Used to amplify the signals • Transistor paved the way to modern technology and electrical devices, leading to smaller radios, calculators, and computers. • This is why this should be awarded the Noble Prize http://en.wikipedia.org/wiki/Transistor
