I had the honour to be in the audience for this talk given by one of the few people who can talk fist hand about the inspiring and important work carried out at Bletchley Park during the Second World War.
Remember Bletchley Park urgently needs our help to remain open as a museum and memorial to the many people like Jerry and their vital work, which for many years had to remain a secret.
