Code Breaker at Bletchley Park
Taught at the University of Toronto and University of Waterloo
Awarded the Order of Canada
Fellow of the Royal Society
William Thomas Tutte, was a British codebreaker and mathematician at Bletchley Park during World War II. He is best known for advancements in decrypting the Lorenz cipher machine, a major German cipher system more sophisticated than the Enigma machine. Breaking the encoding system and deciphering encoded information saved thousands of lives. General Dwight Eisenhower said it shortened the war by at least two years.
Obituary from New York Times
William Tutte, a theoretical mathematician who contributed substantially to breaking codes in World War II, died on May 2 in Kitchener-Waterloo, Ontario. He was 84.
The cause was congestive heart failure complicated by cancer of the spleen, the University of Waterloo announced. He was distinguished professor emeritus of combinatorics and optimization and honorary director of the university's Center for Cryptographic Research.
A chemistry graduate student at Cambridge in 1941, young Mr. Tutte was sent to the now-fabled Bletchley Park, where a secret code-breaking operation had been set up. There, applying solely his mind and logic, he deciphered a key part of the German military code that others, equipped with a model of the German Enigma encrypting machine, had failed to break.
After settling in Canada, he went to the fledgling University of Waterloo in 1962 and helped build its faculty of mathematics into a magnet for theoreticians and students alike. He became a leader in the evolution of combinatorics, the science of counting separate objects, which he first broached in his doctoral thesis more than 50 years ago.
