X-WR-CALDESC:7 August 1958:  American cryptologic pioneer Herbert O. Yardle
 y died. Yardley was inducted into the NSA Cryptologic Hall of Honor in 199
 9 (see link below).\n\nThe following is from his Hall of Honor entry: \n\n
 Born in 1889 in Indiana\, Herbert O. Yardley began his career as a code cl
 erk in the State Department. He accepted a Signal Corps Reserve commission
  and served as a cryptologic officer with the American Expeditionary Force
 s in France during WWI. In the 1920s he was chief of MI-8\, the first U.S.
  peacetime cryptanalytic organization\, jointly funded by the U.S. Army an
 d the Department of State. In that capacity\, he and a team of cryptanalys
 ts exploited nearly two dozen foreign diplomatic cipher systems. MI-8 was 
 disbanded in 1929 when the State Department withdrew its share of the fund
 ing.\n\nOut of work\, Yardley caused a sensation in 1931 with the publicat
 ion of his memoirs of MI-8\, 'The American Black Chamber.' In this book\, 
 Yardley revealed the extent of U.S. cryptanalytic work in the 1920s. Surpr
 isingly\, the wording of the espionage laws at that time did not permit pr
 osecution of Yardley. (This situation was changed two years later with a n
 ew law imposing stiff penalties for unauthorized revelations of cryptologi
 c secrets.)\n\nYardley did some cryptologic work for Canada and China duri
 ng World War II\, but he was never again given a position of trust in the 
 U.S. government.\n\nRead more about Herbert O. Yardley in 'The Many Lives
