Book Description
This book contains a depth of information not found elsewhere concerning William F. Friedman and his three principal assistants, Solomon Kullback, Frank B. Rowlett, and Abraham Sinkov. The events described in this book clearly detail the magnitude of their contributions to the country. Not only did these persons lay the foundation for successful efforts to break and read the enemy's most sensitive messages, but through their efforts U.S. communications remained secure during the War.
