American Cryptology during the Cold War, 1945-1989: Book I: The Struggle for Centralization 1945-1960 [Part 2, excised] [open pdf - 8MB]
This section of Thomas Johnson's history of the National Security Agency (NSA) during the Cold War contains pages 157-287 of Book 1. This encompasses the first one chapter, titled 'The Soviet Problem.' Throughout Book 1, Johnson "explains how cryptology responded to the landmark events and challenges of the post-World War II era. He next provides profound analysis of how events and personalities affected the development of cryptology institutionally and professionally. Finally, and even better, Dr. Johnson spins a fascinating tale of the success or failure of cryptologic operations in the various crises that have challenged the SIGINT system."
