Joseph Oswald Mauborgne co-invented the one-time pad with Gilbert Vernam of Bell Labs. In 1914 he published the first recorded solution of the Playfair cipher. Mauborgne became a Major General in the United States Army, and from October 1937 to his retirement in 1941 was the Army's 12th Chief Signal Officer, in command of the Signal Corps.
