John Bardeen

Bardeen, John (1908–91), U.S. physicist noted for his studies of transistors and superconductors. He shared the 1956 Nobel Prize for physics with W. H. Brattain and W. Shockley, doing much of the research in solid-state physics that led to the development of transistorized electronic equipment. In 1972 he became the first person to win a second Nobel Prize in the same field, sharing the award with L.P. Cooper and J.R. Schrieffer for the development of their theory of superconductivity.
