X-WR-CALDESC:7 April 1882: Birth of Hermann Pokorny\, founder of the Hungar
 ian cryptanalytic service Sub-Group X or Section X. Pokorny was a World Wa
 r I Austro-Hungarian Army cryptologist whose work with Russian ciphers con
 tributed substantially to Central Powers victories over Russia.\n\nDuring 
 World War I\, Pokorny\, as a cryptologist in the rank of major\, headed th
 e Austro-Hungarian General Staff's Russian-Cipher Bureau. He showed great 
 ability in decrypting Russian enciphered military messages that were broad
 cast by radio in 1914–17. He recognized that the Russian cryptographers ha
 d reduced the 35-letter Russian alphabet to 24 letters\, while doubling th
 e 11 missing letters to some of the other 24 letters. His break into the R
 ussian military cipher system enabled Austro-Hungarian and German forces t
 o act in advance of impending Russian maneuvers\, thus contributing substa
 ntially to Central Powers victories over the Russians. He is mentioned in 
 Soviet Marshal Boris Shaposhnikov's famous book\, Мозг армии (The Brain of
  the Army\, 1929). For his services to cryptology\, Pokorny was decorated 
 with the Large Military Merit Medal with Swords in 1918. Founded on April 
 1\, 1916\, this honour was intended for the 'highest especially praisewort
 hy recognition' and was awarded only 30 times. 28 of its recipients were o
 fficers of general's rank\; the other two were the naval aviator Gottfried
  von Banfield (1916) and Pokorny himself. By 1918\, when the Austro-Hungar
 ian Empire fell\, he was a lieutenant colonel.
