This engrossing biography by one of molecular biology's foremost scholars reveals the remarkable evolution of Francis Crick's scientific career and the shaping of his personality. From unpromising beginnings, he became a vital contributor to a remarkably creative period in science. Olby chronicles Crick's life from his early studies in biophysics, to the discovery of the structure of DNA, to his later work in neuroscience and the nature of consciousness. This account is woven together with insights into his personal life gained through access to Crick's papers, family, and friends. Robert Olby's book is a richly detailed portrait of one of the great scientists of our time.
