In this biography, young listeners will learn all about Elizebeth Friedman (1892-1980), a brilliant American code breaker who smashed Nazi spy rings, took down gangsters, and created the CIA's first cryptology unit. Her story came to light when her secret papers were finally declassified in 2015. From thwarting notorious rumrunners with only paper and pencil to โ€œcounter-spying into the minds and activities ofโ€ Nazis, she held a pivotal role in the early days of US cryptology. No code was too challenging for her to crack, and her work undoubtedly saved thousands of lives.
