The Black women codebreakers of the Cold War

During the early Cold War era, the United States Army and later the NSA began recruiting and training codebreakers and intelligence officers to decipher intercepted Soviet messages.

Among those recruits were a group of highly skilled Black women who were employed as cryptologists to decode these messages. But their role in Cold War intelligence operations has been largely overlooked, until now.

Host Flora Lichtman talks with historian Sarah Valentine about her book, “Decoding the Devil: Black Women Codebreakers and the Secret War Against Stalin’s Bomb.”
