 September 6, 1901, President William McKinley is shot by Leon Zogos at the Pan-American Exposition in Buffalo. He dies of gangrene eight days later. October 14, 1912, former President Theodore Roosevelt, seeking the office again, is shot and wounded by John Schrenk while campaigning in Milwaukee. Though he has a bullet in his chest, it passed through a copy of the speech he was to give. Roosevelt addressed the crowd anyway and then goes for medical treatment.
