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 of Manchester in November 1953. The computer was built by Richard Grimsdale, then a research student in the Department of Electrical Engineering and later a Professor of Electronic Engineering at Sussex University. The machine used point-contact transistors, made in small quantities by STC and Mullard. These consisted of a single crystal of germanium with two fine wires, resembling the crystal and cat’s whisker of the 1920s. These transistors had the useful property that a single transistor could possess two stable states. ... The development of the machine was severely hampered by the unreliability of the transistors, which consumed 150 watts.
