Answer:
The Rosenbergs, who were convicted of providing bomb secrets to the Russians, were executed.
Explanation:
Julius Rosenberg and Ethel Greenglass Rosenberg were an American couple that was executed in the electric chair for espionage in favor of the Soviet Union.
Julius Rosenberg was an engineer and worked at the Los Alamos Nuclear Research Center, where the United States had assembled some of the world's best physicists. In 1950, Senator McCarthy announced that the Soviet nuclear test was evidence of communist spies everywhere in the United States. Early in the morning of July 17, 1950, the FBI knocked on the door of Rosenberg's, where Julius was arrested. Later in that year, Ethel was also arrested. The court considered that they had provided very important and sensitive information to the Soviet Union on the production of a hydrogen bomb.
