George Koval (1913–2006) was a Soviet intelligence officer. According to Russian sources, Koval's infiltration of the Manhattan Project as a Soviet Main Intelligence Directorate (GRU) agent "drastically reduced the amount of time it took for Russia to develop nuclear weapons". Koval was born to Jewish immigrants in Sioux City, Iowa. 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 GRU, 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, in addition to descriptions of the weapon production sites. After the war, 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". (more...)
