The Woman Who Smashed Codes: A True Story of Love, Spies, and the Unlikely Heroine Who Outwitted America's Enemies

Jason Fagone’s “The Woman Who Smashed Codes” drags Elizebeth Smith Friedman out of the dusty archives and into the spotlight she’s deserved for decades. This isn’t some dry, textbook biography. It’s a lively, well-researched story about a woman who went from Shakespeare scholar to the backbone of American cryptology. And if you think cryptography is just about geeky ciphers, think again—this was life-and-death spy work that helped shape modern intelligence.

Elizebeth’s journey starts in the early 20th century at Riverbank Laboratories, a curious private research facility funded by a rich eccentric. There, she meets William Friedman, her husband and partner in codebreaking. Together, they didn’t just tinker with puzzles; they laid the groundwork for the US government’s cryptanalytic capabilities long before the NSA or CIA were household names.

World War I was her first proving ground, where her knack for cracking enemy communications made her an invaluable asset. But her story doesn’t stop there. During Prohibition, instead of hunting gangsters with guns, she used her brain to dismantle their secret messages, helping to take down notorious smugglers including Al Capone’s network. And if that sounds like a neat little side gig, wait until World War II, when Elizebeth exposed a sprawling Nazi spy ring in South America, effectively neutering a major threat to the Allied war effort.

The book doesn’t shy away from the frustrating reality that, despite her critical role, Elizebeth’s contributions were often buried under layers of institutional sexism and secrecy. Her husband’s fame and figures like J. Edgar Hoover conveniently overshadowed her work, sometimes even taking credit for what she cracked. Fagone digs into how government agencies, obsessed with secrecy and male egos, actively erased her from history, leaving her as a footnote for decades.

Fagone’s writing style is a breath of fresh air. He makes complex cryptology accessible without talking down to you. The narrative moves briskly, balancing technical detail with human drama—her marriage, her battles against bureaucracy, and her relentless pursuit of truth. It’s a story that feels both epic and intimate.

But it’s not all smooth sailing. Some readers might find the cryptographic explanations a bit dense, especially if you’re not already curious about codebreaking. And the focus on her personal life, especially her relationship with William, sometimes overshadows her solo achievements. Still, that tension adds texture to the story, showing how her identity was tangled up with a husband who was also a legend.

Published amid a wave of interest in forgotten women of history, this book slots neatly into the broader movement to reclaim female pioneers from the sidelines. It’s a reminder that history often isn’t about who did the work, but who got the credit—and that the truth can be messy, unfair, and in need of a good storyteller.

Bottom line? If you’re into spy stories, history, or just want to meet a real-life badass who smashed codes and crushed stereotypes, this book delivers. It’s a worthy call-out to a woman who should have been a household name decades ago.
