John William Jamieson Herivel was a British scientific historian and codebreaker during World War II at Bletchley Park. He is most noted for his discovery of what is known as the Herivel tip, a crucial method for analyzing the Enigma cipher. This technique was based on Herivel's understanding of the behaviors of German Enigma operators, allowing Bletchley Park to deduce parts of daily keys. After the war, he became an academic, focusing on the history and philosophy of science at Queen's University Belfast, particularly studying figures like Isaac Newton.
