George Abramovich Koval (, Zhorzh Abramovich Koval, December 25, 1913 – January 31, 2006) was an American who acted as a Soviet intelligence officer. According to Russian sources, Koval's infiltration of the Manhattan Project as a Glavnoye Razvedyvatel'noye Upravleniye (GRU) agent "drastically reduced the amount of time it took for Russia to develop nuclear weapons."〔Chervonnaya, citing Russian sources.〕 Koval was born to Jewish immigrants in Sioux City, Iowa, USA. Shortly after reaching adulthood he traveled with his parents to the Soviet Union to settle in the Jewish Autonomous Region near the Chinese border. Koval was recruited by the Soviet Main Intelligence Directorate, trained, and assigned the code name DELMAR. He returned to the United States in 1940 and was drafted into the US Army in early 1943. Koval worked at atomic research laboratories and, according to the Russian government, relayed back to the Soviet Union information about the production processes and volumes of the polonium, plutonium, and uranium used in American atomic weaponry, and descriptions of the weapon production sites. In 1948, Koval left on a European vacation but never returned to the United States. In 2007 Russian President Vladimir Putin posthumously awarded Koval the Hero of the Russian Federation decoration for "his courage and heroism while carrying out special missions".〔 == Early life == George Koval's father, Abram Koval, left his home town of Telekhany in Belarus to immigrate to the United States in 1910. Abram, a carpenter, settled in Sioux City, Iowa, which at the turn of the 20th century was home to a sizeable Jewish population of merchants and craftsmen. He and his wife Ethel Shenitsky Koval raised three sons: Isaya, born 1912; George (or Zhorzh), born Christmas 1913; and Gabriel, born 1919.〔Walsh, 42.〕 George Koval attended Central High School, a red-brick Victorian building better known as "the Castle on the Hill". Neighbors recalled that Koval spoke openly of his Communist beliefs. While attending Central High he was a member of the Honor Society and the debate team. He graduated in 1929 at the age of 15. Meanwhile, his parents left Sioux City as the Great Depression deepened. Abram Koval became the secretary for ICOR, the Organization for Jewish Colonization in the Soviet Union.〔 Founded by American Jewish Communists in 1924, the group helped to finance and publicize the development of the "Jewish Autonomous Region" – the Communist answer to Jewish emigration to the British Mandate of Palestine then being undertaken by the Zionist movement.〔Srebrnik, 80–108.〕 The Koval family emigrated in 1932, traveling with a United States family passport.〔 They settled in Birobidzhan, near the border of Manchuria.〔Walsh, 43.〕 The Koval family worked on a collective farm and were profiled by an American Communist daily newspaper in New York City. The journalist Paul Novick wrote to his readers that the family "had exchanged the uncertainty of life as small storekeepers ... for a worry-free existence for themselves and their children."〔 While Isaya became a champion tractor driver, George Koval improved his Russian language skills in the collective and began studies at the Mendeleev Institute of Chemical Technology in 1934. At the university he met and married fellow student Lyudmila Ivanova. Koval graduated with honors in five years and received Soviet citizenship.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「George Koval」の詳細全文を読む スポンサード リンク
