About this title

Synopsis

This book, written by historians of the Army Security Agency, now unclassified, is the story of (1) the War Department's Code and Cipher Section, headed by William F. Friedman, and (2) the Cipher Bureau MI-8), headed by Herbert O. Yardley. The text describes the administration and problems of the Cipher Bureau (MI-8) in New York, as well as the cryptanalytic solutions accomplished by that organization (later to become known as the American Black Chamber). Why the Cipher Bureau (MI-8) ceased operations in 1929 is described in detail. Text includes an index.
