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.
