Sing Sing - Executions

Executions

Four inmates under federal death sentences were executed in the electric chair at Sing Sing. On June 19, 1953, Julius and Ethel Rosenberg were electrocuted for espionage. On August 12, 1952, Gerhard A. Puff was electrocuted for murder. The last prisoner to be executed in the electric chair was Eddie Lee Mays who was convicted of murder and executed on August 15, 1963. In 1972, the United States Supreme Court ruled in Furman v. Georgia that the death penalty was unconstitutional and the chair was no longer used. Altogether, 614 men and women were executed at Sing Sing. The electric chair was later moved to Greenhaven Prison in working condition but was never used again.
