Description

'Gannon's book contains a mass of utterly fascinating and largely unknown material about an immensely important wartime project, and is very welcome indeed.' Brian Randell, TES In 1940, almost a year after the outbreak of the Second World War, Allied radio operators at an interception station in South London began picking up messages in a strange new code. Using science, maths, innovation and improvisation BletchleyPark codebreakers worked furiously to invent a machine to decipher what turned out to be the secrets of Nazi high command. It was called Colossus. What these codebreakers didn't realize was that they had fashioned the world's first true computer. When the war ended, this incredible invention was dismantled and hidden away for almost 50 years. Paul Gannon has pieced together the tremendous story of what is now recognized as the greatest secret of BletchleyPark.show more

Review quote

Paul Gannon has revealed a previously untold story ... [Colossus] tells of the heroic efforts of the inventors and mathematicians [who] received no recognition for decades ... Gannon sets the record straight. -- Simon Singh The Times Seeks to restore Colossus to its rightful place in the history of computing... read Gannon to feel the collective power of human minds harnessed to the cause of defending our freedom. -- Georgina Ferry Guardian Masterly in its breadth and sweep ... Gannon's account of wartime interception and encryption is deeply researched ... I commend the book to both the professional and the general reader. -- Donald Michie Spectatorshow more
