Genius: The Life and Science of Richard Feynman

James Gleick's book Genius is an informative but dutiful biography of the great physicist Richard Feynman. I much prefer Feynman's own memoir (Surely You’re Joking, Mr. Feynman!), or his recorded lectures (see this invaluable resource) or especially his video interviews (the two BBC specials are the best) as a way of more fully appreciating his genius and personality.
