The Codebreakers by David Kahn

[20th-century-personalities]

David Kahn, was a journalist, historian and the world’s pre-eminent expert on cryptology, or the science of secret codes / National Cryptological Museum

His 1967 book, “The Codebreakers,” introduced the world to cryptology and inspired the emergence of private-sector encrypted communication.

Over the course of more than 1,000 pages, along with some 150 pages of notes, Mr. Kahn laid out cryptology’s long history, starting with ancient Egypt 4,000 years ago and proceeding through the French and American revolutions, and the innovations wrought by the advent of the telegraph and telephone to the mid-20th century and the dawn of computer-assisted code breaking.
