Immediately added to my favorites shelf. I cannot recommend this book highly enough.

The Woman Who Smashed Codes will be compared with Hidden Figures, and that's fair, to a point. Both books have at their core a story of remarkable scientific/mathematic achievement, overlooked because of gender, largely forgotten (until now) as others took credit. But it is so much more, so rich in its account of not only an extraordinary woman, but the time in which she lived, two World Wars and her central role in both, the incredible marriage that gave birth to modern American cryptanalysis, that I think it deserves to be evaluated on its own.

Even in the hands of a merely serviceable writer, it would be an enjoyable read. But Fagone elevates the story, weaving it into as rich a tapestry as you could hope for. Secondary characters jump from the page just as much as Elizebeth and her husband William; little details transport you to the small, smoke-filled rooms where Elizebeth and her tiny team toiled in obscurity in defense of the country. Fagone firmly establishes Elizebeth Friedman's place in our history, and not only gives her her due, but demands that we reevaluate what we thought we knew about the wars, and the origins of America's intelligence services (nearly all of them have her fingerprints on them), and the people who are given credit for critical milestones in the country's history.

This is a magnificent, memorable, important book.
