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.
