This episode tells the story of Elizebeth Smith Friedman, one of America's first codebreakers. She and her husband, William Friedman, unwittingly became pioneers in the age of intercepted messages and unraveling the secrets of your enemies. The book, The Woman Who Smashed Codes, by Jason Fagone, walks us through how these two young people were introduced to codebreaking, ciphers and the world of hidden messages before World War I. And once they learned the patterns behind codebreaking, their services became indispensable to defeating the Nazis in World War II. You may not have heard of them, but their tireless work behind the scenes, magically turning indecipherable jumbles of letters into critical Allied intelligence, changed the course of history. We hope you enjoy this episode.
