While Rosie the Riveter became the iconic symbol of women's wartime industrial contributions, another group of women worked in the shadows, their impact immeasurable. Over 10,000 young women-college students, teachers, and mathematicians-were secretly recruited to Washington D.C. to break enemy codes. Their work was so crucial that military leaders later estimated it shortened World War II by at least two years. These women came from elite colleges like Wellesley and Smith, but also from teaching positions in small towns across America. What made them particularly valuable was their educational background-training in languages, literature, music, mathematics, and meticulous attention to detail. They passed rigorous security clearances and were sworn to absolute secrecy, unable to tell even their families about their vital work. By war's end, women constituted nearly 70% of the Army's code-breaking force and 80% of the Navy's domestic cryptanalysts. Their story remained largely untold for decades, their contributions unacknowledged until recently, when the NSA finally began recognizing these remarkable women who helped win the war through the power of their minds.
