Department of Security Studies and International Affairs
"In 1917, Herbert O. Yardley was put in charge of the nation's first code-breaking section of military intelligence, MI8. He was excellent at his job, and when his office was closed down in 1929, he set off a firestorm with his bestselling tell-all book about the secrets of cryptography, American Black Chamber."
