The son of a gardener, he became a British, and later a Canadian, mathematicianand code-breaker. Having graduated with a degree in chemistry from Trinity College, Cambridge, he worked at Bletchley Park, initially on Italian Navy codes but from mid-1941 on Tunny, the signal traffic generated by the Lorenz coding machine. His brilliant and fundamental deciphering work led to the code being broken and, eventually, to the creation of the Colossus computing machine. Post-war he emigrated to Canada where he held senior positions at the universities of Toronto and Waterloo. He had a number of significant mathematical accomplishments, including foundational work in the fields of graph and matroid theories.
