His story had all the elements of wartime danger, espionage, codebreaking and inevitable tragedy. The cryptographer Rolf Noskwith, who has died at the age of 97, was one of the mathematicians working in the famous Hut 8 at Bletchley Park under the ill-fated father of modern computing, Alan Turing, who took his own life after being revealed to be a homosexual.

The story of Bletchley Park and Turing's part in it was the subject of the Oscar-nominated film The Imitation Game. Turing, whose role in intercepting German military codes helped win the war, was portrayed by Benedict Cumberbatch. 

Under Turing’s supervision, Noskwith and his fellow cryptographers and number-crunchers intercepted thousands of high-level enemy communications every day, sometimes within an hour of transmission. So enthralling was the work, that the analyst finishing his shift would be unwilling to “hand over the workings”, as Noskwith observed in Codebreakers: The Inside Story of Bletchley Park. Noskwith’s fluent German was an added asset to the team when assessing encrypted enemy messages.

There were victories but also tragedies. According to Martin Sugarman, chair of the Hackney Anglo-Israel Twinning Association, Noskwith was deeply distressed by the tragedy of the Struma, a ship carrying Jewish refugees to Palestine in 1942, which was sunk with all its 800 passengers including many children. But he successfully deciphered a major German code; a system of coloured flares used to communicate between the enemy’s naval HQ and U boat commanders at sea. Noskwith’s achievement enabled the Allied Navy to know the Nazi military positions.
