Edward Travis

Sir Edward Wilfred Harry Travis (24 September 1888 – 23 April 1956) was a British cryptographer and intelligence officer, becoming the operational head of Bletchley Park during World War II, and later the head of GCHQ.

Career Educated locally in Blackheath, London, Travis joined the Royal Navy in 1906 as a Paymaster officer, and served on HMS Iron Duke. From 1916 to 1918, he worked on Navy cyphers. He retired in 1921, having reached the rank of Paymaster Lieutenant-Commander, and was advanced to Paymaster Commander in 1927.

By 1925, he was in charge of security at the Government Code and Cypher School and deputy to Alastair Denniston. However, Christopher Grey notes that other factors also contributed to Travis' promotion, including a personality clash between Denniston and Stewart Menzies, the Director of the Government Code and Cypher School (GC&CS) and the head of the Secret Intelligence Service, as well as an ongoing and unresolved management crisis in Hut 3. Turing's biographer says that after the change, Travis "presided over an administrative revolution" reconciling the management structure to the production process.

Travis was involved with William Friedman in working on the 1943 BRUSA Agreement and the subsequent 1946 UKUSA Agreement, which forms the basis for all signal intelligence cooperation between the US National Security Agency (NSA) and the UK Government Communications Headquarters (GCHQ) to this day. He remained head of the post-war successor to GC&CS, GCHQ, and served as its director until 15 April 1952, when he was replaced by Eric Jones.
