Joan Clarke

Joan Elisabeth Lowther Murray Clarke (1917-1996) was an English cyrptanalyst known for her work at Bletchley Park during WWII as a “code-breaker.” “Code breakers” were those that worked on decoding a machine that the Germans invented called The Enigma Code that encrypted their messages. While the Germans beleived their machine was unbreakable, Clarke worked on the team that did indeed break the code. For her work she was appointed a Member of the Order of the British Empire in 1946.
