Abstract :
STANDING IN Hut 8 at Bletchley Park last year, I tried to explain to my children how one mathematics professor working in this draughty, wood-partitioned wartime hut 70 years ago became so important in breaking an ´unbreakable´ code, shortening a world war by a couple of years and laying the foundations of the computer industry. The same man was later persecuted by the British government for his homosexuality and driven to suicide. Hut 8 was left to rot.
