Bøger af John Dermot Turing

The Enigma cipher was supposed to be the German's impenetrable defence for its military communications against prying eyes during World War II. All manner of secrets were entrusted to it. When the Allies finally managed to crack the code, it heralded a turning point in the war. This is the fascinating story of how the code was created, adopted by the Nazis, and finally broken. Dermot Turing, the nephew of the great codebreaker Alan Turing, explores the twists and turns of German encryption efforts from the end of World War I through to Hitler's demise and the great lengths to which the Allies went to break it. The Enigma Story reveals the efforts of the codebreakers at Bletchley Park, the machines called 'bombes' specially designed to break it, and the vast resources devoted in America to decrypting German messages. From the cloak-and-dagger heroics of men like Hans-Thilo Schmidt and Gustave Bertrand to the brilliant mathematical discoveries of men like Henryk Zygalski and Dilly Knox to the fraught decision-making of Allied High Command, the battle for the code was at the heart of the Allied victory in World War II. This extraordinary tale of intrigue, ingenuity and courage brings to life the complete story of the Enigma in a lively and entertaining narrative.

'Turing writes on codebreaking with understandable authority and compelling panache.' - Michael Smith, bestselling author of Station X. >Written by Dermot Turing - the nephew of famous codebreaker Alan Turing - this illustrated account provides unique insight into the behind-the-scenes action at Bletchley Park. Discover how brilliant and eccentric individuals such as Dilly Knox, Alan Turing and Joan Clarke were recruited, the social life that grew up around the park, and how they dealt with the ever-present burden of secrecy. Learn about the origins of international intelligence co-operation, as the United States sent representatives from the Army and Navy to learn about the new codebreaking techniques being developed in Britain, and how these experiences shaped efforts to break the Japanese codes. Including a foreword by Professor Christopher Andrew of Cambridge University, author of MI5's official history The Secret World, this book brings to life the stories of the men and women who toiled day and night to crack the seemingly unbreakable enigma code.
