The 1946 Great Seal Bug Story: The US ambassador to the USSR was Averell Harriman. The Russians had Soviet school children present him with a two foot hand craved great seal of the US which he hung in his office. In 1952, a countermeasures survey revealed that the great seal contained a bugging devise. That means that the Soviets were able to eavesdrop on the U.S. ambassador’s conversations for six years. On May 20th 1960, Ambassador Henry Cabot Lodge, Jr. revealed the great seal bug to the UN.
