A Virtual Talk by Dr Ted Coles

Dr Ted Coles will tell the story of the super-secure cipher machine that was developed by Nazi Germany during the Second World War. It was used for sending long telegrams between German High Command and the Generals at the Army group HQs in occupied Europe and North Africa. This machine was code named “Tunny” and its traffic, code named “Fish”.

Without ever having seen the machine, the Bletchley Park cryptanalysts managed to diagnose how it worked and to develop a way of deciphering some 64,000 intercepted messages.

How this was done and the equipment developed – “Heath Robinson” and “Colossus” will be described in an illustrated talk to be followed by a short question and answer session.
