On this day in 1953, Julius and Ethel Rosenberg, convicted of conspiring to pass U.S. atomic secrets to the Soviets, are executed by electric chair at Sing Sing Prison in Ossining, New York. Both refused to admit any wrongdoing and proclaimed their innocence right up to the time of their deaths. The Rosenbergs were the first U.S. citizens to be convicted and executed for espionage during peacetime and their case remains controversial to this day. Julius Rosenberg, born in New York on 12 May 1918, was an engineer for the U.S. Army Signal Corps.
His wife, born Ethel Greenglass, also in New York on 28 September 1915, worked as a secretary. The couple met as members of the Young Communist League. They married in 1939 and had two sons. Julius Rosenberg was arrested on suspicion of espionage on 17 June 1950, and was accused of heading a spy ring that passed top-secret information concerning the atomic bomb to the Soviet Union. Ethel was arrested two months later. The Rosenbergs were implicated by David Greenglass, Ethel's younger brother and a former army sergeant and machinist at Los Alamos, the secret atomic bomb lab in New Mexico.
Greenglass, who himself had confessed to providing nuclear secrets to the Soviets through an intermediary, testified against his sister and brother-in-law in court. He later served 10 years in prison. The Rosenbergs vigorously protested their innocence, but after a brief trial that began on 6 March 1951 and attracted much media attention, the couple was convicted. On 5 April 1951, a judge sentenced them to death and the pair was taken to Sing Sing to await execution.
During the next two years, the couple became the subject of both national and international debate. Some people believed that the Rosenbergs were the victims of a surge of hysterical anti-communist feeling in the United States, and protested that the death sentence handed down was cruel and unusual punishment. Many Americans, however, believed that the Rosenbergs had been dealt with justly. They agreed with President Dwight D. Eisenhower when he issued a statement declining to invoke executive clemency for the pair.
He stated, "I can only say that, by immeasurably increasing the chances of atomic war, the Rosenbergs may have condemned to death tens of millions of innocent people all over the world. The execution of two human beings is a grave matter. But even graver is the thought of the millions of dead whose deaths may be directly attributable to what these spies have done." Julius Rosenberg died first, while three courses of electrocution had to be applied to Ethel before she finally expired. Forty minutes before their deaths, they shared a touching moment when they kissed through the mesh screen separating them.
