Adolf Hitler
Forty hours after Hitler and Eva Braun got married in Berlin, Germany, both of them committed suicide by poisoning themselves with cyanide, then Hitler shot himself in the head with his gun. Before this, Hitler ordered that their bodies be burned. This prevented him from being captured alive by soldiers of the Red Army, who were closing in on him. Despite this, there are theories that Hitler did not die in 1945, but that he instead escaped to Argentina. These theories are very unpopular, with most historians dismissing them.
