by Alan Watson OBE, who will be talking about the cyphers and cypher machines
Alan is a former Merchant Navy radio and electronics officer whose duties included codes and cyphers. This sparked a lifelong interest in the subject and led to a collection of machines, including a German Enigma, which he will demonstrate.
The story of Enigma is now well known, so Alan will concentrate on the development of cypher machines, particularly what made Enigma special and why it was so hard to crack. He will explain the methods to break it, from the Polish cryptographers’ early attempts to the mechanised approach at Bletchley Park.
There will be an opportunity to get “hands-on” with four machines: a German three-rotor, a Swiss NEMA, a Swedish Hagelin and a Russian Fialka.
