John Bardeen and the Theory of Superconductivity

Abstract
When one speaks with John Bardeen's friends about him, one frequently hears words such as brilliant, quiet, persistent, generous, visionary, athletic, kind, thoughtful and remarkable. It is my good fortune to have the chance to recount some incidents from his life that are connected with the theory of superconductivity. This article draws on my personal memories; his many other friends and colleagues will set down their own recollections elsewhere.
