John Bardeen was an American physicist. He is the only person to have won two Nobel prizes in Physics, in 1956 for the transistor, along with William Bradford Shockley and Walter Brattain, and in 1972 for a fundamental theory of conventional superconductivity together with Leon Neil Cooper and John Robert Schrieffer, now called BCS theory.

Sourced

• Science is a field which grows continuously with ever expanding frontiers. Further, it is truly international in scope. Any particular advance has been preceded by the contributions of those from many lands who have set firm foundations for further developments. The Nobel awards should be regarded as giving recognition to this general scientific progress as well as to the individuals involved.
  Further, science is a collaborative effort. The combined results of several people working together is often much more effective than could be that of an individual scientist working alone.

• I guess two Nobel Prizes are better than one hole-in-one.
  • When asked if he were prouder of his Nobel Prizes or his hole-in-one he scored in golf (he was an avid golfer).
