Reviews of David Kahn's latest book The Reader of Gentlemen's Mail:

"Kahn is rightly surprised that H. O. Yardley, 'the most colorful and controversial figure in American intelligence,' has not had a biographer before. Yet if Yardley could read Kahn's account of his exploits, he would surely say that the wait was worth it. An enjoyable read about an important but arcane chapter of American history."--William E. Odom, author of Fixing Intelligence: For a More Secure America

"David Kahn has brought alive the period from the beginning to the middle of the last century in a way that should attract even those readers with no special interest in codes and ciphers. Masterful."--David E. Murphy, author of Battleground Berlin

¡¡ãYardley was both a patriot and a self-serving entrepreneur, and his life raises moral questions as much as it illustrates the history of cryptography. Kahn¡??s biography of Yardley is fascinating reading.¡¡?-Harvey Klehr, coauthor of The Secret World of American Communism and The Soviet World of American Communism

"The world's best expert on codes brilliantly tells the fascinating story of the pioneer American codebreaker."--Arthur Schlesinger

"David Kahn has turned a complex subject, cryptology, and a complex individual, cryptologist Herbert Yardley, into a fascinating, very readable study of the influence of American morality on spying and code breaking. Yardley, a hero in advancing American code breaking, was cast out onto the street when the Secretary of State's famous pronouncement 'Gentlemen do not read each other's mail' closed down Yardley's code breaking operations in 1929 In Kahn's term, Yardley then became a 'rotter' in writing a book about our code breaking in order to make a buck for himself. In time, though, the book had the effect of advancing our ability to read the Japanese codes, a key to our winning World War II. This is an intriguing read about the kind of the intrigue that permeates the world of intelligence."--Stansfield Turner, Admiral, U.S. Navy (Ret.), Director of Central Intelligence, 1977¡¡ï¿½ï¿½C1981
