May 23: American Nobel-winning physicist the late John Bardeen was born in Madison, WI in 1908.
He is the co-inventor of the transistor and the only person to win the Nobel Prize in Physics twice: first in 1956 with William Shockley and Walter Brattain for the invention of the transistor; and again in 1972 with Leon N. Cooper and John Robert Schrieffer for a fundamental theory of conventional superconductivity (BCS theory).
Bardeen, Shockley, and Brattain (L-R in the photo) invented the transistor while they were members of the technical staff at AT&T Bell Labs in New Jersey. Bardeen died in Boston, MA on Jan 30, 1991; he was 82.
