Samuel Joseph Melville (born Samuel Joseph Grossman, 1934 – September 13, 1971), was the principal conspirator and bomb setter in the 1969 bombings of eight government and commercial office buildings in New York City. Melville cited his opposition to the Vietnam War and U.S. imperialism as the motivation for the bombings. He pleaded guilty to conspiracy and to bombing the Federal Office Building in lower Manhattan, as well as to assaulting a marshal in a failed escape attempt. A key figure in the 1971 Attica Prison riots, he was shot and killed when the uprising was put down by force.
