Shaun Wylie is a British mathematician and former World War II codebreaker. Leonhard Euler is considered by many to be one of the greatest mathematicians of all time A mathematician is the person whose primary area of study and research is the field of mathematics. ...

Wylie was born in Oxford, England, and educated at Dragon School and then Winchester College.^[1] He won a scholarship to New College, Oxford where he studied mathematics and classics.^[1] In 1934, he went to study topology at Princeton University, obtaining a PhD in 1937 with Solomon Lefschetz as his supervisor.^[2] At Princeton he met fellow English mathematician Alan Turing.^[1] Oxford is a city and local government district in Oxfordshire, England, with a population of 134,248 (2001 census). ...

During World War II, Turing was at Bletchley Park, Britain's codebreaking centre. Turing wrote to Wylie around December 1940, who was by then teaching at Wellington College, inviting him to work at Bletchley Park.^[3] He accepted, and arrived in February 1941.^[3] He joined Turing's section, Hut 8, which was working on solving the Enigma machine as used by the German Navy. He became head of the crib subsection,^[4] and was a member of a panel of five "bombe controllers" established in mid-1942 to decide how to allocate time on the codebreaking machines.^[5] Combatants Allied Powers Axis Powers Casualties Military dead: 17,000,000 Civilian dead: 33,000,000 Total dead: 50,000,000 Military dead: 8,000,000 Civilian dead: 4,000,000 Total dead 12,000,000 World War II (abbreviated WWII), or the Second World War, was a worldwide conflict...

Wylie transferred in Autumn 1943 to work on "Tunny", a German teleprinter cipher^[6]. He married Odette Murray, a WREN in the section.^[7] In 1945, soon after the victory in Europe, Wylie demonstrated how Colossus — electronic machines used to help solve Tunny — could have been used unmodified to break the Tunny "motor wheels", a task which had been previously done by hand.^[8] While at Bletchley Park, he became president of the dramatic club, and won an unarmed combat competition.^[9] He had also played international hockey,^[9] but according to fellow codebreaker I. J. Good, he "never mentioned any of his successes".^[10] For the fish, see Tuna. ...

After the war, he was a fellow at Trinity Hall and lectured in mathematics.^[11] He was the PhD advisor for Frank Adams, Crispin Nash-Williams, William Tutte and Christopher Zeeman.^[2] With Peter Hilton, he authored Homology Theory: An Introduction to Algebraic Topology, published in 1960.^[10] Full name College of Scholars of the Holy Trinity of Norwich Motto - Named after The Holy Trinity Previous names - Established 1350 Sister College University College All Souls College Master Prof. ...

In 1958, he became Chief Mathematician at GCHQ, the UK signals intelligence organisation.^[2] In July 1969, he was sent a draft paper by James H. Ellis, another GCHQ mathematician, about the possibility of what was termed "non-secret encryption", or what is now more commonly known as public-key cryptography, on which Wylie commented "unfortunately, I can't see anything wrong with this".^[12] He retired in 1973, and taught at Hills Road Sixth Form College in Cambridge for seven years.^[2] The Government Communications Headquarters (GCHQ) (previously named the Government Code and Cipher School (GC&CS)) is the main British intelligence service providing signals intelligence (SIGINT). ...
