Parker Hitt

Born in 1878, Parker Hitt was a United States Army officer, West Point graduate, and early specialist in military communications and cryptography. He is often remembered as an important figure in the development of American military code and cipher practice, especially in the years before and during the early 20th century.

Alongside his Army service, he wrote technical works including Manual for the Solution of Military Ciphers, a book that helped explain how military ciphers could be analyzed and solved in a systematic way. His writing is valued not only as military history, but also as a clear window into the beginnings of organized U.S. cryptologic thinking.

Hitt died in 1971. Reliable page-image checks during this search did not produce a confirmed usable portrait, so no profile image is included here.
