Today in Labor History February 11, 1953: Cold War: U.S. President Dwight D. Eisenhower denied all appeals for clemency for Julius and Ethel Rosenberg. The government executed them at Sing Sing in 1953. They had been convicted of espionage for the USSR. Their sons, Michael and Robert Meeropol (adopted by Abel Merepol, composer of the anti-lynching song “Strange Fruit,”), maintained their parents’ innocence. However, after the fall of the Soviet Union, decoded Soviet cables showed that their father had collaborated. They continued to fight for the mother’s pardon, but Obama refused to grant it.
