John Bardeen Home Up About 'John Bardeen' Advertisement John Bardeen May 23 January 30 ) was a physicist who was the co- inventor of the transistor . He developed a fundamental theory for conventional superconductivity together with Cooper and Schrieffer; today known as the BCS theory He was born in Madison, Wisconsin Bardeen studied Physics as a graduate student at Princeton, with Nobel Laureate Eugene Wigner In 1956, Bardeen received the Nobel Prize in physics for the transistor . Amazingly, he received it again in 1972 for the BCS theory . No other physicist has received it twice. Bardeen was also an important advisor to the Xerox Corporation . Though quiet by nature, he took the rare step of urging Xerox executives to keep their California research center, Xerox PARC , afloat when the parent company was suspicious that its research center would amount to little. Xerox PARC went on to create the point-and-click method, the mouse, and the laser printer, among other things.

John Bardeen was born in Madison, Wisconsin, May 23, 1908. He attended the University High School in Madison for several years, and graduated from Madison Central High School in 1923. This was followed by a course in electrical engineering at the University of Wisconsin , where he took extra work in mathematics and physics. After being out for a term while working in the engineering department of the Western Electric Company at Chicago, he graduated with a B.S. in electrical engineering in 1928. He continued on at Wisconsin as a graduate research assistant in electrical engineering for two years, working on mathematical problems in applied geophysics and on radiation from antennas. It was during this period that he was first introduced to quantum theory by Professor J.H. Van Vleck Professor Leo J. Peters, under whom his research in geophysics was done, took a position at the Gulf Research Laboratories in Pittsburgh, Pennsylvania. Dr. Bardeen followed him there and worked during the next three years (1930-33) on the development of methods for the interpretation of magnetic and gravitational surveys. This was a stimulating period in which geophysical methods were first being applied to prospecting for oil. Because he felt his interests were in theoretical science, Dr. Bardeen resigned his position at Gulf in 1933 to take graduate work in mathematical physics at

One of the problems was how do we do this, so we'd just coat the point with paraffin all over, and then we'd push it down on the crystal. When john bardeen was told what had happened he thought of a new way to make an amplifier. On November 21, bardeen suggested pushing a metal point into the silicon http://www.pbs.org/transistor/background1/events/miraclemo.html

"So I toyed around in my mind: How can I do this experiment I was still being lazy; of course I could have evacuated the thing, but that was the sample that had been fixed up to put down in this thermos and it wasn't exactly conducive to evacuation; and it would have taken some time to do this." Walter Brattain, January 1964 (p.28) "I think I suggested, 'Why, John, we'll wax the point.' One of the problems was how do we do this, so we'd just coat the point with paraffin all over, and then we'd push it down on the crystal. The metal will penetrate the paraffin and make contact with the semi-conductor, but still we'd have it perfectly insulated from the liquid, and we' ll put a drop of tap water around it. That day, we in principle, created an amplifier." Walter Brattain, January 1964 "This circuit was actually spoken over and by switching the device in and out a distinct gain in speech level could be heard and see on on the scope presentation with no noticeable [sic] change in quality."

Bardeen, John Bardeen By courtesy of University of Illinois at Urbana-Champaign (b. May 23, 1908, Madison, Wis., U.S.d. Jan. 30, 1991, Boston, Mass.), American physicist who was cowinner of the Nobel Prize for Physics in both 1956 and 1972. He shared the 1956 prize with William B. Shockley and Walter H. Brattain for their joint invention of the transistor . With Leon N. Cooper and John R. Schrieffer he was awarded the 1972 prize for development of the theory of superconductivity. Bardeen earned bachelor's and master's degrees in electrical engineering from the University of Wisconsin (Madison) and obtained his doctorate in 1936 in mathematical physics from Princeton University. A staff member of the University of Minnesota, Minneapolis, from 1938 to 1941, he served as principal physicist at the U.S. Naval Ordnance Laboratory in Washington, D.C., during World War II. After the war Bardeen joined (1945) the Bell Telephone Laboratories in Murray Hill, N.J., where he, Brattain, and Shockley conducted research on the electron-conducting properties of semiconductors. On Dec. 23, 1947, they unveiled the transistor, which ushered in the electronic revolution. The transistor replaced the larger and bulkier vacuum tube and provided the technology for miniaturizing the electronic switches and other components needed in the construction of computers. In the early 1950s Bardeen resumed research he had begun in the 1930s on superconductivity, and his Nobel Prize-winning investigations provided a theoretical explanation of the disappearance of electrical resistance in materials at temperatures close to absolute zero.

Bardeen, John US physicist who won a Nobel prize 1956, with Walter Brattain and William Shockley , for the development of the transistor 1948. In 1972 he became the first double winner of a Nobel prize in the same subject (with Leon Cooper and Robert Schrieffer (1931- ) for his work on superconductivity. At the Bell Telephone laboratory, New Jersey, 1945-51, in a team with Shockley and Brattain, Bardeen studied semiconductors, especially germanium, used in radar receivers in the same way that crystals had been used in the earliest radio sets. The work led to the development 1956 of the transistor. The second Nobel prize was won for explaining superconductivity, the total loss of electrical resistance by some metals when cooled within a few degrees of absolute zero. The theory developed in 1957 by Bardeen, Schrieffer, and Cooper states that superconductivity arises when electrons travelling through a metal interact with the vibrating atoms of the metal.

Bardeen, John (1908-1991) Nació en Madison (Wisconsin) el 23 de Mayo de 1908, hijo del Dr. Charles R. Bardeen y Althea Harmer. El Dr. Charles R. Bardeen era profesor de anatomía de la escuela médica de la Universidad de Wisconsin en Madison. Después de la muerte de Althea, cuando John tenía 12 años, el Dr. Bardeen se casó con Ruth Hames. John Bardeen asistió a la High School en Madison unos cuantos años, pero se graduó en el Madison Central High School en 1923. A continuación, siguió un curso en ingeniería eléctrica en la Universidad de Wisconsin, en el cual la mayor parte del trabajo extra que tenía lo dedicó a las matemáticas y a la física. Después de estar fuera por una temporada, mientras estaba trabajando en el departamento de ingeniería del "Western Electric Company" de Chicago, se graduó con el grado B.S. en Ingeniería eléctrica en 1928. Continuó en el mismo centro de Wisconsin durante dos años como investigador asistente graduado en ingeniería eléctrica, trabajando en problemas matemáticos en aplicaciones geofísicias y en radiaciones de antenas. En este período tuvo su primera introducción a la teoría cuántica de manos del profesor J. H. Van Vleck. El profesor Leo J. Peters, encargado de la investigación en geofísica, fue destinado a los laboratorios de Investigación del Golfo en Pittsburgh (Pennsylvania), Bardeen se fue con él, trabajando durante los 3 años siguientes (1930-1933) en el desarrollo de métodos para la interpretación de medidas mágneticas y gravitacionales. Éste fue un período estimulante en el que se aplicaron, por primera vez,los métodos geofísicos a la prospección de petróleo.

"John Bardeen was the most intelligent human being that I've ever met" John and his siblings, 1917 "John is the concentrated essence of the brain," Althea once wrote to her father-in-law. "It was on the way between my high school and home so that I would stop and see her on the way home from school. I remember stopping in to see her on the day before she died. I thought she looked well that day and cheerful and I was shocked to hear the next day that she had passed away. I didn't realize how seriously ill she was." Part 1,( John Bardeen "Whispering John" Early Heartbreak John Bardeen was born on May 23, 1908 in Madison, Wisconsin. He was the second son of Dr. Charles Russell Bardeen, dean of the University of Wisconsin medical school, and Althea Harmer Bardeen, a well-educated young woman who had studied art and design at the Pratt Institute in Brooklyn. Bardeen was a brilliant kid right from the beginning his parents decided to move him from third grade up into junior high. When Bardeen was 12, his mother became seriously ill with cancer. Thinking he was helping his kids, Dr. Bardeen downplayed the seriousness of her illness. John didn't realize she was dying, and was stunned when it happened. His father quickly married his secretary, Ruth Hames
