This is the illustrated biography of Richard Feynman, probably the most gifted physicist of his time. His story is told through personal reminiscences from his family, friends and colleagues, and is illustrated with over 100 photographs of Feynman at work and off-duty. Feynman's career included work on the atomic bomb, a Nobel Prize for Physics, theoretical research on quarks, and his dramatic discovery of the cause of the Challenger shuttle disaster. He was also an artist, a traveller and a joker.
