Alan Turing: The Enigma

"One of the finest scientific biographies I've ever read: authoritative, superbly researched, deeply sympathetic, and beautifully told."--Sylvia Nasar, author of A Beautiful Mind "A captivating, compassionate portrait of a first-rate scientist who gave so much to a world that in the end cruelly rejected him. Perceptive and absorbing, Andrew Hodges's book is scientific biography at its best."--Paul Hoffman, author of The Man Who Loved Only Numbers "A remarkable and admirable biography."--Simon Singh, author of The Code Book and Fermat's Enigma "A first-rate presentation of the life of a first-rate scientific mind.... It is hard to imagine a more thoughtful and compassionate portrait of a human being."--from the Foreword by Douglas Hofstadter
