Yardley was chief of the first peacetime cryptanalytic organization in the United States, the ancestor of today's National Security Agency. Funded by the U.S. Army and the Department of State and working out of New York, his small and highly secret unit succeeded in breaking the diplomatic codes of several nations, including Japan. The decrypts played a critical role in U.S. diplomacy. Despite its extraordinary successes, the Black Chamber, as it came to known, was disbanded in 1929. President Hoover's new Secretary of State Henry L. Stimson refused to continue its funding with the now-famous comment, "Gentlemen do not read other people's mail." In 1931 a disappointed Yardley caused a sensation when he published this book and revealed to the world exactly what his agency had done with the secret and illegal cooperation of nearly the entire American cable industry. These revelations and Yardley's right to publish them set into motion a conflict that continues to this day: the right to freedom of expression versus national security. In addition to offering an exposé on post-World War I cryptology, the book is filled with exciting stories and personalities.

Book excerpt: The first novel in a brand-new alternate history series where Teddy Roosevelt is president for a second time right before WWI breaks out, and on his side is the Black Chamber, a secret spy network watching America's back. 1916. The Great War rages overseas, and the whole of Europe, Africa, and western Asia is falling to the Central Powers. To win a war that must be won, Teddy Roosevelt, once again the American president, turns to his top secret Black Chamber organization--and its cunning and deadly spy, Luz O'Malley Aróstegui. On a transatlantic airship voyage, Luz poses as an anti-American Mexican revolutionary to get close--very close--to a German agent code-named Imperial Sword. She'll need every skill at her disposal to get him to trust her and lead her deep into enemy territory. In the mountains of Saxony, concealed from allied eyes, the German Reich's plans for keeping the U.S. from entering the conflict are revealed: the deployment of a new diabolical weapon upon the shores of America...

Book Synopsis The Reader of Gentlemen's Mail by : David Kahn

Download or read book The Reader of Gentlemen's Mail written by David Kahn. This book was released on 2008-10-01. Available in PDF, EPUB and Kindle. Book excerpt: One of the most colorful and controversial figures in American intelligence, Herbert O. Yardley (1889-1958) gave America its best form of information, but his fame rests more on his indiscretions than on his achievements. In this highly readable biography, a premier historian of military intelligence tells Yardley's story and evaluates his impact on the American intelligence community. Yardley established the nation's first codebreaking agency in 1917, and his solutions helped the United States win a major diplomatic victory at the 1921 disarmament conference. But when his unit was closed in 1929 because "gentlemen do not read each other's mail," Yardley wrote a best-selling memoir that introduced-and disclosed-codemaking and codebreaking to the public. David Kahn de-scribes the vicissitudes of Yardley's career, including his work in China and Canada, offers a capsule history of American intelligence up to World War I, and gives a short course in classical codes and ciphers. He debunks the accusations that the publication of Yardley's book caused Japan to change its codes and ciphers and that Yardley traitorously sold his solutions to Japan. And he asserts that Yardley's disclosures not only did not hurt but actually helped American codebreaking during World War II.
