The first full biography of Albert Einstein since all of his papers have become available shows how his scientific imagination sprang from the rebellious nature of his personality. Biographer Isaacson explores how an imaginative, impertinent patent clerk--a struggling father in a difficult marriage who couldn't get a teaching job or a doctorate--became the locksmith of the mysteries of the atom and the universe. His success came from questioning conventional...
