Bletchley Park code breaker

Bill Tutte memorial (behind red car)

Bill Tutte was a local man (he lived near Newmarket) who worked at Bletchley Park as a code breaker during WW2.  He was probably more important than Turing, although his code breaking remained a national secret until not many years ago. The work Tutte did was used to intercept Russian traffic in the Cold War! There is now a memorial to him in Newmarket, as shown in the photo.

Polish code breakers - the unknown story

Until reading the article on the BBC website I had no knowledge of the part played by Polish codebreakers in decyphering the German Enigma code. See http://www.bbc.co.uk/news/magazine-28167071 .

There is little doubt that the work of the Bletchley codebreakers helped to shorten the war. I had no idea that Polish codebreakers were so important too.
