THE MAN WHO BROKE PURPLE:  THE LIFE OF COLONEL WILLIAM F. FRIEDMAN, WHO DECIPHERED THE JAPANESE CODE IN WORLD WAR II., Clark, Ronald.
1 Clark, Ronald. THE MAN WHO BROKE PURPLE: THE LIFE OF COLONEL WILLIAM F. FRIEDMAN, WHO DECIPHERED THE JAPANESE CODE IN WORLD WAR II.
Boston Little Brown 1977 0316145955 / 9780316145954 First American Edition Hard Cover Very Good Very Good- 
271 pp, 8 1/2" H. B&w photographs. "(T)ells the story of William Friedman, the master cryptographer who solved the 'unbreakable' Japanese cipher system, 'Purple', used by the Imperial navy and the Japanese embassy in Berlin. (This) is the first full-scale, authorized biography of the attractive but driven leader of the only wartime enterprise as top secret as the manufacture of the first atomic bomb. (It) provides a sober account of how America's early, scattered intelligence agencies burgeoned steadily without foresight into a modern bureaucracy characterized by pathological secrecy and ethical ambiguity - and how such expansion took a severe toll on Friendman's mental and physical health. Clark discloses how much the Purple decipherments contributed to the Allied offensive in Europe and, most of all, influenced the outcome of the war in the Pacific: how the Battle of Midway and the ambush of Yamamoto's plane over Bougainville were decided by decoded Purple messages; and how, tragically, circumstances prevented the deciphered warnings of an impending attack from being understood in time at Pearl Harbor. A thoughtful biography of a dapper figure who transformed cryptography from a remote craft 'run by guess and by God' to a complex science, (it) triumphs in its recreation of those agonizing hours when the fate of our fleet in the Pacific, and its officers and men, was determined by a handful of men with only small strips of paper sitting in a room thousands of miles away." Light wrinkling at top/bottom of spine. Dust jacket has light edge wear/creasing - mainly at top/bottom of spine and flap-folds, crease down front flap at fore-edge, one small edge tear with crease, protected in a mylar sleeve. 
Price: 20.00 USD
