One of the Second World War's most fascinating stories is that of the Enigma machine, a portable encryption device widely used by the Germans, whose ciphers they believed to be totally secure. Nevertheless, by mathematical analysis and modern technology (and a certain amount of good luck), the Allies devised techniques for 'breaking' Enigma ciphers, and thus read several million German messages, providing a wealth of reliable intelligence. The attack on Enigma, initiated by the Poles in the 1930s, was later perfected by the British at Bletchley Park, today open to the public as a museum site.

After the lecture, the audience are invited to take part in a hands-on practical demonstration of one of the few surviving Enigma machines.
