Elizebeth Smith Friedman (1892-1980) was a pioneering American cryptanalyst and author who deciphered enemy codes in both World Wars and Prohibition. Often dubbed 'America's first female cryptanalyst,' she and her husband, William F. Friedman, are considered the founders of modern American cryptology. Her career began at Riverbank Laboratories, where she applied her literary analysis skills to codebreaking. During Prohibition, she led efforts for the U.S. Coast Guard and Bureau of Prohibition, breaking complex codes used by rum runners and smugglers, leading to numerous convictions. In World War II, her team broke various German Enigma machine codes used by Nazi spies in South America, significantly aiding Allied counter-espionage efforts. Despite her crucial contributions, much of her work remained classified for decades, and her achievements were often overshadowed by her husband's or attributed to others. After the war, she created a secure communications system for the International Monetary Fund. Elizebeth Friedman's meticulous work and groundbreaking techniques laid a foundational stone for modern signals intelligence.
