You meant "John Mail"!

John Mail is a British author and journalist, best known for his work on the Enigma machine and the codebreaking efforts of the British Government Code and Cypher School (GC&CS) at Bletchley Park during World War II.

Mail was a member of the team that worked on the Enigma machine, and he was one of the first people to crack the code. He also worked on other codes and ciphers, including the German Lorenz cipher.

Mail's work on the Enigma machine and other codes was highly classified during the war, and he was not able to speak publicly about his work until many years later. He wrote several books about his experiences, including "The Enigma War" and "Codebreaker".

Mail's contributions to the field of cryptography and codebreaking are still recognized today, and he is considered one of the most important figures in the history of codebreaking.
