图书简介
In this picture book biography, young readers 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 “counter-spying into the minds and activities of” Nazis, Elizebeth held a pivotal role in the early days of US cryptology. No code was too challenging for her to crack, and Elizebeth’s work undoubtedly saved thousands of lives. Extensive back matter includes explanations of codes and ciphers, further information on cryptology, a bibliography, a timeline of Elizebeth’s life, plus secret messages for young readers to decode.
