The Codebreakers – Enigma, Bletchley Park & the Battle of the Atlantic

October 1, 2015 @ 6:00 pm - 8:00 pm

| Free

Enigma, Bletchley Park & The Battle Of The Atlantic – an illustrated presentation by Dr Mark Baldwin.

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, 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 early 1930s, was later perfected by the British at Bletchley Park, today open to the public as a museum site.

The Intelligence gained was of immense value to the Allies in virtually every theatre of war, but nowhere more so than in the Battle of the Atlantic, that fierce conflict which lasted nearly six years and cost over 60,000 lives. Dr Baldwin uses the Battle of the Atlantic to exemplify the importance of code breaking in winning the war.

After the presentation, the audience are invited to take part in a hands-on practical demonstration of one of the few surviving Enigma machines. Only about 300 are known to survive worldwide; of these, only about a dozen are in public collections in Britain. As these machines are so rare, Dr Baldwin is providing a unusual opportunity for the audience not just to view, but also to operate, an original U-Boat Enigma machine – the actual machine which appears in the recent film, ‘The Imitation Game’.

Having delivered over 500 presentations, Dr Baldwin is one of Britain’s most experienced speakers on the Enigma machine and the work of the WW2 code breakers. He has travelled widely throughout Britain addressing a variety of audiences – professional, educational, commercial and the general public – and has also been invited to speak in Germany, Belgium and Poland.

The talk will take place in the Sir Ian Wood Building (Formerly Riverside East) at 18:00 for a 18:30 start. Room tba nearer the time.
