100 PEOPLE YOU NEVER KNEW WERE AT BLETCHLEY PARK

In 1939, ever increasing numbers of budding cryptanalysts started reporting for wartime duty at a country house in north Buckinghamshire. Musicians, society debutants and novelists were among the women and tweedy, owlish young men, their heads filled with astounding equations and barely comprehensible calculations. The 10,000 men and women who worked at Bletchley Park had to sign the Official Secrets Act and they kept their vow of silence implacably for decades afterwards. Some died without the satisfaction of even their own families knowing about their crucial work breaking the German and Japanese codes. Belatedly however the secret was lifted, and now Sinclair McKay chooses a hundred of Bletchley Park's alumni to tell the stories of their whole lives, and not just the wartime interlude. Sometimes the distinction as chess players, musicians or linguists was what saw these young people selected. For others the intense intellectual crucible seems to have galvanised their ambition and widened their horizons, and sent them out into the post-war world determined to make a difference with their lives. Here then are the historians and archaeologists, novelists and naturalists, but also classics masters, a Nuremberg prosecutor and an associate of Andy Warhol - everyone from Roy Jenkins to the man who wrote the music for the Dracula films, and from the woman who saved St Pancras Station to Prince Philip's first girlfriend, and even those unfairly judged during their lives not to have amounted to much at all. 250pp, eight pages of photos.
