Talk at the Pitstone & Ivinghoe Museum Society. Held in the meeting room at Pitstone Green Museum at 8pm on 27-2-14.
Members and non-members welcome.
After a variety of careers our speaker, Rob Johnstone, is a volunteer guide at the Bletchley Park Museum when he is not trying to sail round Britain single handed in a 23ft boat. This talk will be a non-technical introduction to codes, ciphers, enigmas, combes and lots more.
