On October 22, 1926, Houdini was performing in Montreal at the Princess Theater. Before the show, Harry was in his dressing room laying on the couch. While relaxing backstage, a young athlete from McGill University asked Houdini if he really could withstand punches to the stomach, as he had heard. Houdini said yes and would prove it to the boy. But before he could tighten his stomach, the student started punching Houdini. Harry didn't realize it, but his appendix had ruptured. After Houdini performed in Montreal, he headed to Detroit. He did only one performance there and then collapsed and was rushed to the hospital. Harry Houdini did not die in a stunt, nor did he drown, as most people believe. The greatest magician of all time died on October 31, 1926, of peritonitis. (source).
