Bletchley Park was the centre for the WW2 British Empire code-breaking effort, often referred to as Ultra, which broke a large part of the encoded German Enigma radio traffic.

Alan Turing one of the key people there has come to the fore:
This week sees the 100th anniversary of the birth of Alan Turing, a man regarded as one of the most influential mathematicians of the 20th Century. He is best known for his work cracking the Germans' secret codes during the Second World War. He is also regarded as one of the pioneers of computer technology.

Recently Warwick Business School hosted an event with three speakers, each using a different perspective:
Chris Grey explores how Bletchley Park was made as an organisation. What was its culture and how was its work co-ordinated? Challenging many popular perceptions Chris examines the complexities of how 10,000 people were brought together in complete secrecy and yet worked as a team.
I've followed his work for a few years and he has made an important contribution to understanding what occurred at Bletchley Park. This is a short interview:http://www2.warwick.ac.uk/knowledge/culture/chrisgrey

Then two historians:
Michael Smith an award-winning journalist and number one best-selling author; an expert on codebreaking, espionage and how spies operate.

Richard Aldrich, Professor of International Security at the University of Warwick who is an expert in the technology of secrecy. He talks about what happened to Bletchley Park after the end of the Second World War and how it transformed into GCHQ..
