Decode the story of Elizebeth Friedman, the cryptologist who took down gangsters and Nazi spies! Friedman was a brilliant American code breaker who created the CIA's first cryptology unit. No code was too challenging for her to crack, and Elizebeth's work undoubtedly saved thousands of lives. And yet almost nobody knew about her work until her secret papers were finally declassified in 2015.
From thwarting notorious rumrunners with only paper and pencil to counter-spying into the minds and activities of Nazis, this picture book follows Elizebeth as she established a pivotal role in the early days of US cryptology. Extensive back matter includes explanations of codes and ciphers, further information on cryptology, a bibliography, a timeline of Elizebeth's life, and even secret messages for young readers to decipher.
