[edit] Early life and education

Hugh Alexander was born on 19 April 1909 in Cork, Ireland, the eldest child of Conel William Long Alexander, an engineering professor at University College, Cork, and Hilda Barbara Bennett.[1] His father died in 1920, and the family moved to Birmingham in England where he attended King Edward's School.[1] He won a scholarship to study mathematics at King's College, Cambridge in 1928, graduating with a first in 1931.[1]

From 1932, he taught mathematics in Winchester, and married Enid Constance Crichton on 22 December 1934.[1] In 1938 he left teaching and became head of research at the John Lewis Partnership.[1]

[edit] Bletchley Park and GCHQ

In February 1940 Alexander arrived at Bletchley Park, the British codebreaking centre during World War II. He joined Hut 6, the section tasked with breaking German Army and Air Force Enigma messages. In 1941, he transferred to Hut 8, the corresponding hut working on Naval Enigma. He became deputy head of Hut 8 under Alan Turing. Alexander was more involved with the day-to-day operations of the hut than Turing, and, while Turing was visiting the United States, Alexander formally became the head of Hut 8 around November 1942.

In October 1944, Alexander was transferred to work on the Japanese JN-25 code.

In mid-1946, Alexander joined GCHQ, which was the post-war successor organisation to the Government Code and Cypher School (GCCS) at Bletchley Park. By 1949, he had been promoted to the head of "Section H" (cryptanalysis), a post he retained until his retirement in 1971.

[edit] Chess career

He represented Cambridge University in the Varsity chess matches of 1929, 1930, 1931 and 1932 ( he studied at King's College, Cambridge). He was twice a winner of the British Chess Championship, in 1938 and 1956. He represented England in the Chess Olympiad six times, in 1933, 1935, 1937, 1939, 1954, and 1958. He was also the non-playing captain of England from 1964 to 1970. He was awarded the International Master title in 1950 and the International Master for Correspondence Chess title in 1970. He won Hastings 1946/47 with the score 7½/9, a point ahead of Savielly Tartakower.[2][3] His best tournament result may have been first equal (with David Bronstein) at Hastings 1953/54 where he went undefeated and beat Soviet grandmasters David Bronstein and Alexander Tolush in individual games. Alexander's opportunities to appear abroad were limited as he was not allowed to play chess in the Soviet bloc because of his secret work in cryptography.[4] He was also the chess columnist of The Sunday Times in the 1960s and 1970s.

"In playing through an Alekhine game one suddenly meets a move which simply takes one's breath away. "
