Alan  Mathison Turing 

During the Second World War, Turing worked for the Government Code and Cypher School (GC&CS)  at Bletchley Park, Britain's codebreaking center. For a time he led Hut 8, the section responsible for German naval cryptanalysis. After the war, he worked at the National Physical Laboratory, where he designed the ACE, among the first designs for a stored program computer. In 1948 Turing joined Max Newman's Computing laboratory at Manchester University, where he assisted development of the Manchester computers and became interested in mathematical biology.
