ALAN TURING: THE ENIGMA New Audiobook Edition is Out Now


Andrew Hodges‘s acclaimed, best-selling ALAN TURING: THE ENIGMA is available now in a new UK audiobook edition. Published by W. F. Howes, and read by Gordon Griffin, here’s the synopsis…

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

Alan Turing was the mathematician whose cipher-cracking transformed the Second World War. Taken on by British Intelligence in 1938, as a shy young Cambridge don, he combined brilliant logic with a flair for engineering. In 1940 his machines were breaking the Enigma-enciphered messages of Nazi Germany’s air force. He then headed the penetration of the super-secure U-boat communications.

But his vision went far beyond this achievement. Before the war he had invented the concept of the universal machine, and in 1945 he turned this into the first design for a digital computer.

Turing’s far-sighted plans for the digital era forged ahead into a vision for Artificial Intelligence. However, in 1952 his homosexuality rendered him a criminal and he was subjected to humiliating treatment. In 1954, aged 41, Alan Turing took his own life.

As mentioned in the synopsis above, Hodges’s book was adapted into the acclaimed, Oscar-winning hit movie The Imitation Game. The print and eBook editions of ALAN TURING: THE ENIGMA are published by Vintage in the UK, and Princeton University Press in North America.

Here are just a few of the many great reviews Hodges’s book has received…

  • ‘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

    ‘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

Czech out this new paperback edition of ALAN TURING: THE ENIGMA…


Andrew Hodges‘s critically-acclaimed ALAN TURING: THE ENIGMA is available now as a paperback in Czechia. Published by Jota, here’s the synopsis…

Alan Turing se zapsal do historie jako vynikající matematik a zakladatel moderní informatiky, jehož práce na prolomení německých kódů rozhodujícím způsobem ovlivnila průběh druhé světové války. Stydlivého absolventa Cambridge, obdařeného brilantní logikou a technickým nadáním si povšimli britští zpravodajci a od roku 1938 ho zaměstnávali ve svém kryptoanalytickém oddělení, sídlícím v Bletchley Parku. První velký úspěch slavil Alan Turing v roce 1940, kdy jeho stroje rozluštily šifrované zprávy německého letectva. Poté se spolupracovníky obrátil pozornost k prolomení dokonaleji zabezpečené komunikace nepřátelských ponorek. Jeho schopnosti a vizionářství ovšem sahaly mnohem dále. Ještě před válkou přišel s konceptem univerzálního stroje, jenž se v roce 1945 zhmotnil do prvního návrhu programovatelného počítače. Turingův smělý rozlet na prahu počítačové éry však v roce 1952 zastavilo odhalení jeho homosexuality, které z něj učinilo společenského vyvrhele a vystavilo ho ponižujícímu zacházení. O dva roky později, zavržený okolím, svůj život dobrovolně ukončil a Velká Británie tak ztratila jednoho ze svých největších vědců a myslitelů. Obsáhlá, zevrubná biografie se opírá o bohatý poznámkový aparát, text doplňuje fotografická příloha. Knižní předloha oscarového filmu Kód Enigmy s B. Cumberbatchem v hlavní roli.

ALAN TURING: THE ENIGMA is published in the UK by Vintage, and in the US by Princeton University Press. The biography was also adapted into the Oscar-winning movie THE IMITATION GAME, starring Benedict Cumberbatch, Keira Knightley, Charles Dance and Mark Strong.

As you can clearly see from these covers, ALAN TURING: THE ENIGMA was adapted for screen as The Imitation Game. In case you haven’t seen the Oscar-winning movie, here’s the trailer…

French Documentary series about ALAN TURING, featuring Andrew Hodges


Earlier this month, France Culture broadcast a mini-documentary series about Alan Turing, the genius mathematician who cracked Germany’s Enigma Code (among other achievements). Andrew Hodges, author of ALAN TURING: THE ENIGMA was a contributor to the series. All of the episodes are available from the France Culture website.

Hodges’s Turing biography published by Michel Lafon in France (and Canada),  Here’s the synopsis…

Génie de l’informatique et héros de la Seconde Guerre mondiale, Alan Turing est célèbre pour avoir décrypté les communications codées de l’armée allemande en venant à bout d’Enigma, la machine de chiffrement utilisée par les nazis, réputée inviolable.

Il faut dire que lorsqu’il « casse » le code secret allemand, à moins de 30 ans, le mathématicien n’en est pas à son premier coup d’éclat. Déjà, en 1936, il a dessiné les contours d’une première machine programmable, ou « machine de Turing », capable d’effectuer n’importe quel calcul mathématique : c’est l’ancêtre de l’ordinateur.

Après la guerre, Alan Turing poursuit ses recherches et se consacre en pionnier aux possibilités offertes par l’intelligence artificielle. Mais l’ex-héros national est persécuté à cause de son homosexualité et condamné en 1952 à la castration chimique. Deux années plus tard, à l’âge de 41 ans, Alan Turing met fin à ses jours en croquant une pomme empoisonnée au cyanure.

Cette biographie, qui mêle histoire des sciences, politique et philosophie, nous dévoile la vie hors norme de l’inventeur, longtemps méconnu, qui a révolutionné nos vies.

Swedish Edition of ALAN TURING: THE ENIGMA out now!


HodgesA-AlanTuringTheEnigmaSWE

Andrew Hodges‘s critically-acclaimed, bestselling ALAN TURING: THE ENIGMA, is available in Swedish! Published by Fri Tanke as ALAN TURING: DATAGENI, KODKNÄCKARE OCH GAYIKON, here’s the synopsis…

Den brittiska matematikern Alan Turing räddade de allierade från nazisterna, uppfann datorn, grundade forskningsfältet artificiell intelligens och förekom gayrörelsen med flera decennier – och allt detta innan fyrtioett års ålder då han tog sitt eget liv.

Andrew Hodges mångfacetterade och hyllande biografi över datavetenskapens grundare är ett djup­gående porträtt av ett extraordinärt liv och intellekt. I en rörande berättelse om matematik, datorer, kryptografi och homofobi fångar Hodges både den inre och den yttre dramatiken i Turings liv.

Hodges beskriver hur Turings revolutionerande idé om en universell maskin redan 1936 lade grunden för den moderna datorn och hur Turing med sin elektroniska design förverkligande samma idé 1945.

Boken beskriver också hur detta arbete direkt relaterade till Turings nyckelroll i arbetet med att knäcka tyska kryptokoder under andra världskriget, en vetenskaplig bedrift som var väsentlig för att möjliggöra de allierades seger.

Men det är också en tragisk berättelse om en man som trots sitt stora bidrag till världsfreden och vetenskapen blev arresterad, och tvingades genomgå en förödmjukande behandling, bara för att han ville leva ett ärligt liv i ett samhälle som betraktade homosexualitet som ett brott.

Boken blev film 2015, med Benedict Cumberbatch och Keira Knightley i huvudrollerna.

ALAN TURING: THE ENIGMA out this month in Dutch


HodgesA-AlanTuringTheEnigmaTIGNED-Blog

This month, Andrew Hodges‘s critically-acclaimed ALAN TURING: THE ENIGMA will be available in Dutch! Published by Hollands Diep as ALAN TURING, HET ENIGMA, here’s the Dutch synopsis…

Er is niet veel overdreven aan de stelling dat de Britse wiskundige Alan Turing de geallieerden heeft gered in hun strijd tegen de Nazi’s, dat hij de uitvinder was van de computer, de bedenker van kunstmatige intelligentie en een voorloper in de strijd om vrijheid voor homoseksuelen – en dat alles voordat hij, 41 jaar oud, zelfmoord pleegde.

Deze schitterende biografie vertelt het definitieve verhaal van een uitzonderlijk genie en een even uitzonderlijk leven.

Alan Turings grote kracht was zijn briljante analytische geest gecombineerd met zijn gave voor het ontwerpen van ‘intelligente’ machines. In 1940 wist hij met zijn vindingen de Duitse Enigma-code te kraken – de code waarmee de Duitse lucht- en zeemacht alle communicatie beveiligde. Hij bracht er het Duitse  oorlogscommando een slag mee toe die de oorlog bekortte en vele mensenlevens redde.

Het was niet Turings enige wapenfeit. Al voor de oorlog werkte de briljante wiskundige aan het concept van een universele machine, een idee dat hij in 1945 uitwerkte tot de allereerste digitale computer. In 1952 kwam een abrupt einde aan de glansrijke carrière van Alan Turing, toen hij door de autoriteiten werd opgepakt wegens homoseksualiteit, een strafbaar feit dat in die tijd nog actief werd vervolgd

In het land dat hij zes jaar lang in het belang van de vrijheid had gediend, volgde een veroordeling en een mensonterende behandeling. In 1954 pleegde Alan Turing, 41 jaar oud, zelfmoord.

Alan Turing, het Enigma verscheen voor het eerst in 1983 en kreeg een glorieuze ontvangst. Enkele jaren geleden volgde een herziene editie, ingeleid door Douglas Hofstadter.

The biography, which was the inspiration for the Oscar-winning movie THE IMITATION GAME starring Benedict Cumberbatch and Kiera Knightley, is published in the UK by Vintage and in the US by Princeton University Press. It has also been published widely in translation (with more editions to come). Here’s the English-language synopsis…

The full story behind the persecuted genius of wartime codebreaking and the computer revolution.

A new edition to celebrate Alan Turing’s centenary, includes a new foreword by the author and a preface by Douglas Hofstadter.

Alan Turing was the extraordinary Cambridge mathematician who masterminded the cracking of the German Enigma ciphers and transformed the Second World War. But his vision went far beyond this crucial achievement. Before the war he had formulated the concept of the universal machine, and in 1945 he turned this into the first design for a digital computer.

Turing’s far-sighted plans for the digital era forged ahead into a vision for Artificial Intelligence. However, in 1952 his homosexuality rendered him a criminal and he was subjected to humiliating treatment. In 1954, aged 41, Alan Turing committed suicide and one of Britain’s greatest scientific minds was lost.

Andrew Hodges’ BBC Alan Turing Timeline


HodgesA-AlanTuringTheEnigmaTIGEng-Blog

Andrew Hodges, the author of the New York Times-bestelling biography ALAN TURING: THE ENIGMA, has put together a Turing Timeline for the BBC.

ALAN TURING: THE ENIGMA has been adapted into an Oscar-winning movie, THE IMITATION GAME, which was released last year. Tie-in editions of the book (above) are published in the UK by Vintage Books and in the US by Princeton University Press. Here’s the synopsis…

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 acclaimed 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 realisation 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 biography has once again hit the New York Times bestseller list, this time at #10 on the Science list:

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.

Andrew Hodges’s ALAN TURING: THE ENIGMA is published in the UK by Vintage Books and in the US by Princeton University Press.

In related news, THE IMITATION GAME won the prestigious Writers Guild Award for Best Adapted Screenplay. The movie also won the USC Libraries Scripter Award back in January. So, you know, you should really go see it. And then read the book.

Andrew Hodges‘s ALAN TURING: THE ENIGMA has been named as one of the best physical science books of 2014 by the Guardian newspaper.

In case you are unfamiliar with the book, here is the synopsis…

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 acclaimed 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 realisation 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.

Published in the UK by Vintage Books and in the US by Princeton University Press, ALAN TURING: THE ENIGMA is also the inspiration behind THE IMITATION GAME, a film starring Benedict Cumberbatch and Keira Knightley, which has been generating plenty of Oscars and other award buzz. (The covers above are for the UK and US tie-in editions.)

In related news, and of interest to Turing fans everywhere, Andrew Hodges has penned some catalogue copy for a rare, secret notebook of the mathematician’s which will be sold at auction in April 2015: ‘Alan Turing was parsimonious with his words and everything from his pen has special value. This notebook shines extra light on how, even when he was enmeshed in great world events, he remained committed to free-thinking work in pure mathematics.’
