Decoding the communication of the Nazi high command was imperative for the success of the Allied invasion of Normandy. The Nazi missives were encrypted by the "Tunny" cipher, a code that was orders of magnitude more difficult to crack than the infamous Enigma code. But Tommy Flowers, a maverick English working-class engineer, devised the ingenious, daring, and controversial plan to build a machine that could think at breathtaking speed and break the code in nearly real time. Together with the pioneering mathematician Max Newman and Enigma code-breaker Alan Turing, Flowers and his team produced--against the odds, the clock, and a resistant leadership--Colossus, the world's first digital electronic computer, the machine that would help bring the war to an end. With fascinating detail and illuminating insight, David A. Price's Geniuses at War tells, for the first time, the mesmerizing story of the great minds behind Colossus, and chronicles their remarkable feats of engineering genius which ushered in the dawn of the digital age"--- Subjects: Cryptography; Lorenz cipher system.; World War, 1939-1945;

- Secret days : code-breaking in Bletchley Park / by Briggs, Asa,1921-2016,author.(CARDINAL)130360;
Includes bibliographical references and index.Map of Bletchley Park -- BP : an introduction -- Cambridge -- Getting inside BP -- The huts -- and Hut Six in particular -- Two camps -- and more -- Ways of escape -- The end of the war -- Getting outside BP -- Oxford -- The Bletchley Trust -- Appendix: Selective chronology.The Bletchley Park memoir of Lord Asa Briggs will be one of the most important documents to be published in 2010. Lord Briggs has long been regarded as one of Britain's most important historians. He has never, however, written about his time at Bletchley Park. The publication, which coincided with Lord Briggs 90th birthday, is a meticulously researched account of life in Hut Six, written by a codebreaker who worked there for five years alongside Alan Turing and Gordon Welchman. In addition to discussing the progress of the Allies' code-breaking efforts and their impact on the war, Lord Briggs considers what the Germans knew about Bletchley and how they reacted to revelatory memoirs about the Enigma machine which were not published until the 1970s. Briggs himself did not tell his wife about his wartime career until the 1970s and his parents died without ever knowing their son's contribution to the wartime effort.- Subjects: History.; Personal narratives.; Briggs, Asa, 1921-2016.; Great Britain.
