John Bardeen was born in 1908 to Charles Russell and Althea Harmer Bardeen. His father was dean of the University of Wisconsin medical school. Bardeen was an extraordinary student who went from third grade straight to junior high school. He started college at the University of Wisconsin, where he earned both his bachelor's and master’s degrees in electrical engineering, in 1928 and 1929. For three years, Bardeen worked as a geophysicist at Gulf Research Laboratories, in Pittsburgh. He earned a doctorate in mathematical physics at Princeton University, in 1936.
Bardeen taught at Harvard University for a few years and married Jane Maxwell in 1938 while living in Cambridge. They had three children. During World War II he worked at the Naval Ordnance Labs to help design defense systems against magnetic mines and torpedoes. After the war he accepted a generous offer from William Shockley to work at Bell Labs. He worked especially well with Walter Brattain, another member of Shockley’s research group. In 1947 Bardeen and Brattain developed the point-contact transistor, which was based on the insight that electrons behave differently at the surface of metals. In June 1948, the invention was announced, and its first commercial use would be on telephone switching equipment four years later. Shockley quickly made improvements on the transistor design and developed the junction transistor. The three shared the 1956 Nobel Prize in Physics.
In 1951 Bardeen quit Bell Labs to take an academic position at the University of Illinois. At the University of Illinois Bardeen studied superconductivity and developed a theory about how extremely cold metals function as such good conductors. In 1971 he was awarded the IEEE Medal of Honor for "his profound contributions to the understanding of the conductivity of solids, to the invention of the transistor, and to the microscopic theory of superconductivity." The following year he was awarded a second Nobel Prize for this work. Bardeen consulted for Xerox, General Electric, and other companies interested in applying theoretical physics to technology. He remained active at the University of Illinois for the rest of his career and was still involved in the scientific community when he died in 1991, from a heart attack.
Bardeen also served on the President's Science Advisory Committee from 1959 to 1962, and on the White House Science Council in the early 1980's. His honors included the National Medal of Science in 1965, the Presidential Medal of Freedom in 1976, and the Lomonosov Prize from the Soviet Academy of Sciences in 1988. He received 16 honorary degrees and was elected to the National Academy of Sciences, the National Academy of Engineering, and the American Philosophical Society.
