Bar·deen

(bär-dēn′), John 1908-1991. American physicist who was one of the inventors of the transistor (1947) and later helped to develop the theory of superconductivity. Bardeen's research explained why the electrical resistance of certain materials disappears at temperatures close to absolute zero, thereby allowing a current to flow through them.
