Nope...another Bell Labs creation: John Bardeen, William Shockley, and Walter Brattain, scientists at the Bell Telephone Laboratories in Murray Hill, New Jersey, were researching the behavior of crystals (germanium) as semi-conductors in an attempt to replace vacuum tubes as mechanical relays in telecommunications. The vacuum tube, used to amplify music and voice, made long-distance calling practical, but the tubes consumed power, created heat and burned out rapidly, requiring high maintenance. The team's research was about to come to a fruitless end when a last attempt to try a purer substance as a contact point lead to the invention of the "point-contact" transistor amplifier. In 1956, the team received the Nobel Prize in Physics for the invention of the transistor. inventors.about.com Orca
