About this person
Joan Clarke was born 24 June 1917 in England and became a cryptanalyst at Bletchley Park during the Second World War, working on the Enigma project that cracked German military communications. She did not seek recognition, but her contribution to decrypting secret messages earned her appointment as a Member of the Order of the British Empire in 1946. After the war she pursued numismatics and lived away from public attention. She died 4 September 1996.
