Presentation by Alan Marchant:
Bletchley Park was the home of what we now call GCHQ, during World War II. It was a huge and ground-breaking intelligence gathering factory where over 9000 people worked in total secrecy. Who were this eclectic team of code breakers? What was life like for these unsung heroes? How were the many challenges of signals intelligence met? What were their great successes and how did BP help to shorten the war and save so many lives?
