Alcatel-Lucent 1947, John Bardeen, Walter Brattain, William Shockley of Bell Labs invented the transistor. In 1956, they received a Nobel Prize for their invention. The transistor led to an electronics revolution during the post-war boom. The transition from vacuum tubes to transistors enabled all technologies to be built on a smaller scale and use less electricity. Items that before required large dedicated spaces, could now fit into a home or even on a kitchen counter. In 1954, Gerald Pearson, Darryl Chapin and Calvin Fuller invented the solar cell. Telstar, the first active communications satellite also developed by Bell Labs and launched
History of the transistor Technical Memorandum calling for votes: Pierce recalled the naming somewhat differently: The Nobel Foundation states that the term is a combination of the words "transfer" and "resistor". The world's first commercial transistor production line was at the Western Electric plant on Union Boulevard in Allentown, Pennsylvania. Production began on Oct. 1, 1951 with the point contact germanium transistor. By 1953, the transistor was being used in some products, such as hearing aids and telephone exchanges, but there were still significant issues preventing its broader application, such as sensitivity to moisture and the fragility of the wires attached to germanium crystals.
