Julius and Ethel Rosenberg, a married couple convicted of conspiracy to commit espionage in 1951, were put to death in the electric chair on June 19, 1953. Their dual execution marked the dramatic finale of the most controversial espionage case of the Cold War.
Julius was arrested in July 1950, and Ethel in August of that same year, on the charge of conspiracy to commit espionage. Specifically, they were accused of heading a spy ring that passed top-secret information concerning the atomic bomb to the Soviet Union.
