Audrey Ruth Churchill (née Briggs) (1920–2005) was a cryptanalyst at Bletchley Park during the Second World War.[1]


Churchill was the youngest daughter of Rev. Canon and Mrs. GW Briggs.[2] She had two sisters and two brothers, one of whom, David, became Headmaster of King's College School, Cambridge.[2]

She graduated in Modern Languages from Newnham College,Cambridge and from 1942-1945, as an expert in German, worked at Bletchley Park as a member of the Z Watch, which translated the decrypted messages.[3][4][5][6][7] She worked variously in Huts 4 and 5, Block A(N), and Naval Section NS I - German Cryptography.[3][5]

Churchill's work has been recognised as instrumental in breaking the most difficult codes used by the Axis powers during the war.[8] This is noted since 70% of the Bletchley Park operation consisted of female codebreakers but few were recognised for their work.[9]

In 1946 she married former SOE Officer Major Oliver Churchill DSO MC in Worcester Cathedral where her father G.W. Briggs was a Canon, and her oldest son is Toby Churchill.
