Herbert Yardley

Herbert Osborne Yardley (13 April 1889-7 August, 1958) was an American cryptologist most known for his book The American Black Chamber (1931). The title of the book refers to the cryptographic organisation of which Yardley was the founder and head — MI8; under Yardley, the cryptanalysts of the American Black Chamber broke Japanese diplomatic codes and were able to furnish American negotiators with significant information during the Washington Naval Conference of 1921-1922. He later helped the Nationalists in China break Japanese codes and worked briefly for the Canadian government, helping it set up a cryptological section.
