Roosevelt was attacked by a deranged innkeeper named John Schrank, who shot the president as he was about to deliver a speech. The bullet passed through Teddy's coat, through his steel eyeglass case, and was finally slowed down by the manuscript of the 50-page speech that Roosevelt was carrying within his jacket.
After being shot point-blank in the chest, Teddy stepped onto the stage -- as blood was beginning to spread across his shirt -- and delivered the speech anyway. The bullet stayed lodged in his chest for the rest of his life.
