70 years of cryptanalysis

XU staff, 1942

Today, June 9th, 2011, is the 70th anniversary of cryptanalysis in Canada.

Canada's first cryptanalytic agency, the Examination Unit, began operations on 9 June 1941. Shown above, the XU staff in mid-1942. Oliver Strachey, a British cryptanalyst seconded from GC&CS to replace Herbert Yardley as head of the XU, is seated in the third row from the front, second from left.
