Harry Houdini, born as Erik Weisz, died on October 31, 1926, due to complications from a ruptured appendix. It is believed that Houdini's appendix had ruptured after being punched by a student who wanted to test his claims of having a strong stomach. However, this theory is still disputed.

Houdini
Many guys punched Harry Houdini, it was a common Houdini stunt that he frequently invited people to do to demonstrate how he could not be hurt. Nothing happened to any of them as Houdini wanted them to punch him. If you mean the guy that caught Houdini by surprise before he could prepare as he needed to for this to prevent injury, probably contributing to the ruptured appendix that killed Houdini a couple weeks later - nothing. He likely suffered from self imposed guilt though. Remember, Harry Houdini's act involved inviting punishment and potential injury and appearing to be unaffected!

A popular but misleading explanation states that a McGill student, in an attempt to test Harry Houdini's widely known strength, punched the magician in his stomach, thus causing his untimely death. On October 20th, 1926, Houdini had been visiting McGill University, giving students a presentation on his recent debunking of a Boston medium. Later on after the presentation at least two students came to visit him: Jocelyn Gordon Whitehead and Samuel J. Smilovitz, who decided to sketch Houdini. During the course of the meeting, Jocelyn Gordon Whitehead decided to challenge Houdini's strength and, without warning Houdini, delivered about three non-malicious punches to his stomach. It appears that Whitehead's punch to Houdini's stomach, while not fatal, aggravated an existing but still undetected case of appendicitis. Although in serious pain, Houdini nonetheless continued to travel without seeking medical attention.
You are likely to be punched in the stomach if you just had a large meal, such as Thanksgiving.
Houdini used to do this act where he would flex his muscles and he would get someone from the audience to come and punch him. Well after one of his shows a guy surprised him and punched him in the stomach without him flexing. Houdini was severely winded but recovered enough to offer to repeat the attempt; the punch bounced off his flexed muscles. However, later Houdini was taken ill and later died of a burst appendix.
You could die. If the attacker hits hard enough, that spot in your nose, called the "bridge", will break. The cartilage gets forced into the brain.
