At present there are just three extracts available. One describes the Alan Turing's emotional and intellectual inspiration at sixteen, one the moral and political ambience of King's College, Cambridge, during Alan Turing's early years there. The third explains the origin of modern computer programming in Alan Turing's 1946 report.

The centenary edition, 2012
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, in The Times Literary Supplement.
Essential in 2009
One of 'Ten essential books on technology', chosen by John Ridpath in the New Statesman, 4 May 2009.
Essential in 2006
Two decades ago, a mathematician named Andrew Hodges published 'Alan Turing: The Enigma', which is one of the finest scientific biographies ever written, and has remained an essential resource for all subsequent accounts of Turing's life.
Jim Holt, in the New Yorker, March 2006
Essential Book for 2002
Listed as one of the essential 50 books of all time in the The Guardian, 1 June 2002.
Comment in 2000
I was fortunate to have available Andrew Hodges's poignant, beautifully written biography of Turing.
Martin Davis, in The Universal Computer
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.
Comment in November 1997
'I wish I'd written,' by Ray Monk
Ray Monk is biographer of Wittgenstein, Bertrand Russell and Robert Oppenheimer. His column in the series 'I wish I'd written' appeared in The Guardian on 13 November 1997:
There are many things I wish I could write, but realise I never will: poetry, drama, travelogues, situation comedies, to mention but a few. But a book I wish I had written, and one that was a big inspiration for the things I have written, is Alan Turing: the Enigma by Andrew Hodges. I read it when it first came out in 1983, and immediately formed the ambition to write something similar about Ludwig Wittgenstein.
Hodges's great achievement was to link the work and life of a scientist in a way that had scarcely been attempted before, and in a manner that avoided many of the obvious pitfalls. Hodges, like Turing, is a mathematician, and was thus able to understand and describe Turing's pioneering work in mathematical logic — and his momentously important codebreaking work during the war — at a depth that would have been beyond most biographers. Like Turing also, Hodges is gay, and his description of Turing's prosecution in 1952 for 'gross indecency' and the tragic events leading up to it, is written with great empathy and an entirely appropriate indignation.
It is an almost perfect match of biographer and subject, and, though Hodges is determined, as he puts it, 'to overcome the twentieth-century chasm between scientific thought and human life,' he has the sensitivity to realise that the events of a person's life can never 'explain' the greatness of their thought. Rather than attempt such an explanation, he integrates the work with the life, allowing the reader to see the connections between the two. In doing so, he created not only a great book, but a whole new kind of biographical writing.
Desert Island Book Choice by Margaret Boden
Prof. Margaret Boden, asked by the New Scientist to choose just one book for its edition of 22 November 1997, wrote:
My choice is the biography Alan Turing... by Andrew Hodges. This superb biography satisfies many of the intellectual senses. Written by a mathematician, it describes in plain language Turing's work on the foundations of computer science and how he broke the Germans' Enigma code in the Second World War. The subtle depiction of class rivalries, personal relationships, and Turing's tragic end are worthy of a novel. But this was a real person. Hodges describes the man, and the science that fascinated him — which once saved, and still influences, our lives.
Some earlier reviews
This book is a first-rate presentation of the life of a first-rate scientific mind... it is hard to imagine a more thoughtful and warm biography than this one.
Douglas Hofstadter, New York Times Book Review,
later included in Metamagical Themas
It is a first-class contribution to history and an exemplary work of biography.
I. J. Good, Nature
Andrew Hodges's book is of exemplary scholarship and sympathy. Intimate, perceptive and insightful, it's also the most readable biography I've picked up in some time.
Richard Rayner, Time Out
... the first serious synthesis of mathematical and gay liberationist insight... a new standard in writing about gay people in the past. It is the moving story of a man with a brilliant mind, who refused to deny his feelings, in a search to understand — and live — true life.
Hubert Kennedy, The Advocate

Media and Arts developments
Alan Turing: the Enigma was the basis for the 1986 play Breaking the Code by Hugh Whitemore, which has played in London, New York and elsewhere, starring Sir Derek Jacobi.
In 1996 it appeared as a television film, also featuring Derek Jacobi.
The television film The Strange Life and Death of Dr Turing was made for the BBC Horizon series in December 1991, and first shown on 9 March 1992. The film-maker was Christopher Sykes.
See a YouTube clip marked as 'The Death of Alan Turing.'
Music: A Man from the Future, 2014
During 2014, the Pet Shop Boys (Neil Tennant and Chris Lowe) will complete and perform a new musical work, A man from the future, with texts from Alan Turing: the Enigma.
They performed a segment of the work, He dreamed of machines, during a concert in Salford with the BBC Philharmonic Orchestra, broadcast on 6 December 2012.
Alan Turing: the Enigma also inspired the late artist and sculptor Sir Eduardo Paolozzi. See my illustrated talk on Paolozzi's Turing prints (2000).
