John Bardeen & Walter Brattain achieve transistor action in a germanium point-contact device in December 1947. Encouraged by Executive Vice President Mervin Kelly, William Shockley returned from wartime assignments in early 1945 to begin organizing a solid-state physics group at Bell Labs.
Walter Houser Brattain (/ ˈ b r æ t ən /; February 10, 1902 – October 13, 1987) was an American physicist at Bell Labs who, along with fellow scientists John Bardeen and William Shockley, invented the point-contact transistor in December 1947.
In 1956, John Bardeen shared the Nobel Prize in Physics with William Shockley of Semiconductor Laboratory of Beckman Instruments and Walter Brattain of Bell Telephone Laboratories "for their researches on semiconductors and their discovery of the transistor effect".
Nov 20, 2022 · Its inventors were a soft-spoken Midwestern theoretician, John Bardeen, and a voluble and “ somewhat volatile ” experimentalist, Walter Brattain. Both were working under William Shockley, a relationship that would later prove contentious. In November 1947, Bardeen and Brattain were stymied by a simple problem.
