Roberto Urbano Viaux Marambio (May 25, 1917 in Talca – September 5, 2005 in Santiago) was a Chilean Army General and the primary planner of two attempted coups d'état in Chile in 1969 and 1970.
General Schneider's official car was ambushed at a street intersection in the capital city of Santiago, Chile.
Though he was rushed to a military hospital, General Schneider's wounds proved fatal and he died three days later, on October 25.
Critics of U.S. policy in Chile at the time, including journalist Christopher Hitchens, have accused former U.S. National Security Advisor and Secretary of State Henry Kissinger of conspiring with Viaux in the murder of General Schneider.
