From the archives: Reading Stimson's mail

Research output: Contribution to journalArticle

Abstract

Henry L. Stimson is best known to readers of this journal for his quote, "Gentlemen do not read each other's mail," and his shutting down of Herbert O. Yardley's black chamber. The present piece reveals a second cryptologic episode from his life. During WWII, Stimson made a request of hundreds of libraries that they withdraw all material on explosives, secret inks, and ciphers from circulation and report the names of anyone requesting these materials to the local office of the Federal Bureau of Investigation (FBI). A pair of original documents is reproduced for the first time along with some references. A list of libraries contacted is also provided.
