Gevork Vartanian (February 17, 1924 - January 10, 2012) was a Soviet Armenian intelligence officer primarily responsible for preventing Operation Long Jump, a Nazi assassination attempt on Winston Churchill, Franklin D. Roosevelt, & Joseph Stalin at the Tehran Conference in 1943 during World War II. Vartanian was born to Armenian parents in Nor Nakhichevan, USSR. His father was also a Soviet intelligence officer. Gevork was 16 years old when he joined Soviet intelligence in 1940 & had been assigned to recruit agents. Vartanian’s team of 7 intelligence officers had identified 400 Nazi agents, all of whom were arrested by Soviet troops. In 1942, Adolf Hitler carefully planned Operation Long Jump under the supervision of the Security Police Chief. They sent Hitler’s special commando agent & six other men to meet in Tehran to capture and/or assassinate Joseph Stalin, Winston Churchill & Franklin D. Roosevelt, the “Big Three,” during the conference. In 1943, Vartanian and his team were assigned the task of ensuring the security at the Tehran Conference after the initial tip from another Soviet intelligence officer about the potential assassination attempt. Vartanian & his team located an advance party of 6 German radio operators who were dropped by parachute near Qom, 37 miles from Tehran. They tailed the Germans to Tehran where their network had set them up in a villa. From there the German spies radioed intelligence reports back to Berlin, which were all intercepted & decoded. The reports revealed that a second group, led by the special commando agent, were to be dropped into Tehran for the assassination attempt. All the members of the first group were arrested & forced to contact their handlers under Soviet supervision. The operation got off track & the second group of German spies never went to Tehran. Thus the success of Vartanian's group in preventing the assassination of the “Big Three”. He was 19 years old at the time. In 1984, Vartanian was recognized for his role in uncovering Operation Long Jump. He was awarded the Gold Star Medal of the Hero of the Soviet Union for his service. Gevork Vartanian passed away at the age of 87 in Moscow.
