Bests & Worsts Reviews from Amazon

Anyone interested in the History of cryptography knows William F. Friedman, known as the man who broke Purple the Japanese cipher machine and many things. But who did know that his wife, née Elizebeth Smith, was his equal in cryptographic skills? She created a Coast Guard cryptographic team, broke an Enigma without any help from Bletchley Park, helped expose many Prohibition-era gangs and Nazi spy networks in South America during WWII and worked in tandem with William during WWI. She is as much part of cryptographic history as her husband is. This is her history in that book, I highly recommended it. I knew she was very good but I didn't know she was that good. Thanks to the author for the book, loved it.
