Alan Turing: The Enigma

Explores the life of the mathematician, reveals the character of the man behind such concepts as the universal machine and the scientific understanding of the mind, and discusses his pioneering role in electronic computer design.

"Turing's rehabilitation from over a quarter-century's embarrassed silence was largely the result of Andrew Hodges's superb biography, Alan Turing: The Enigma (1983; reissued with a new introduction in 2012). Hodges examined available primary sources and interviewed surviving witnesses to elucidate Turing's multiple dimensions. A mathematician, Hodges ably explained Turing's intellectual accomplishments with insight, and situated them within their wider historical contexts. He also empathetically explored the centrality of Turing's sexual identity to his thought and life in a persuasive rather than reductive way."---Michael Saler, Times Literary Supplement

Klappentext
"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

Zusammenfassung
A NEW YORK TIMES BESTSELLER

The official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira Knightley

It is only a slight exaggeration to say that the British mathematician Alan Turing (1912-1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades--all before his suicide at age forty-one. This New York Timesbestselling biography of the founder of computer science, with a new preface by the author that addresses Turing's royal pardon in 2013, is the definitive account of an extraordinary mind and life.


Capturing both the inner and outer drama of Turing's life, Andrew Hodges tells how Turing's revolutionary idea of 1936--the concept of a universal machine--laid the foundation for the modern computer and how Turing brought the idea to practical realization in 1945 with his electronic design. The book also tells how this work was directly related to Turing's leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was critical to Allied victory in the Atlantic. At the same time, this is the tragic account of a man who, despite his wartime service, was eventually arrested, stripped of his security clearance, and forced to undergo a humiliating treatment program--all for trying to live honestly in a society that defined homosexuality as a crime.


The inspiration for a major motion picture starring Benedict Cumberbatch and Keira Knightley, Alan Turing: The Enigma is a gripping story of mathematics, computers, cryptography, and homosexual persecution.
