Over 10,000 American women secretly cracked enemy codes during WWII, saving countless lives. "Code Girls" unveils this classified chapter of history that remained hidden for decades. What strategic intelligence advantage did these unsung heroines provide that generals couldn't?
Liza Mundy, New York Times bestselling author of Code Girls: The Untold Story of the American Women Code Breakers of World War II, is an award-winning journalist and historian specializing in uncovering overlooked contributions of women in pivotal historical events. A former staff writer for The Washington Post and fellow at the New America Foundation, Mundy merges rigorous research with narrative flair to illuminate themes of cryptography, military intelligence, and gender dynamics. Her work has appeared in The Atlantic, Politico, and Smithsonian, solidifying her reputation in historical non-fiction.
Mundy’s expertise extends to her acclaimed book The Sisterhood: The Secret History of Women at the CIA, which explores women’s evolving roles in intelligence, and Michelle: A Biography, a detailed portrait of former First Lady Michelle Obama.
Code Girls became a cultural touchstone, praised for its meticulous storytelling and comparison to Hidden Figures. It won the 2018 “Best General Audience Intelligence Book” award and spent over 20 weeks on bestseller lists, with translations in multiple languages. Mundy’s collaborations with institutions like the CIA Archive further underscore her authority in documenting women’s untold legacies.
Code Girls chronicles the untold story of over 10,000 American women recruited during WWII to break enemy codes, shortening the war and pioneering modern computing. Liza Mundy combines declassified documents, survivor interviews, and historical context to highlight their intellectual rigor, secrecy, and societal impact.
History enthusiasts, feminists, and STEM-focused readers will appreciate this exploration of women’s wartime contributions. Ideal for those interested in cryptography, WWII narratives, or stories of overlooked female pioneers.
Yes—it’s a meticulously researched account of wartime cryptography and gender dynamics. While some technical sections may challenge casual readers, the blend of personal stories, historical significance, and feminist themes makes it compelling.
They deciphered Japanese and German military codes, enabling Allied forces to intercept attacks, save lives, and strategize effectively. Their work directly influenced pivotal battles like Midway and exposed Axis supply routes.
Beyond complex codebreaking, they navigated societal sexism, secrecy oaths, and false public personas (e.g., claiming to be secretaries). Many hid their work for decades, even from family.
No—their contributions were classified for over 50 years. Mundy’s book helped bring late recognition to their legacy, though most died without public acknowledgment.
They cracked Japan’s PURPLE cipher and German Enigma codes, decrypting naval movements, diplomatic messages, and military plans. This intelligence was critical to Allied strategy.
It highlights temporary wartime shifts, where women excelled in STEM roles despite societal expectations. Post-war, many were pressured to return to domestic roles, though some transitioned into early computing fields.
Their analytical methods laid groundwork for computer programming and cybersecurity. Many alumni joined projects like ENIAC, bridging wartime codebreaking to the digital age.
Some reviewers note uneven pacing, with dense technical sections overshadowing personal narratives. However, its thorough research and historical importance outweigh these issues.
Unlike male-centric war narratives, Mundy centers women’s intellectual labor, offering a fresh perspective on intelligence operations and gender roles in historical crises.
The U.S. Army and Navy recruited top students from women’s colleges and teacher pools, emphasizing math and language skills. Many joined after male peers enlisted, filling critical wartime roles.

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.
