The couple, who were both members of the American Communist Party, were accused of passing atomic bomb secrets to the Soviet Union. In 1951, they were convicted of espionage and sentenced to death. The Rosenberg case fueled widespread fear and paranoia about Communist infiltration and espionage in the United States. The execution of the Rosenbergs in 1953 remains one of the most controversial and debated acts of treason in American history.
