Today is the one-hundred twenty-sixth birthday of the most infamous of historical figures Adolf Hitler. "Uncle Adolf" was the leader of the Nazi party, ruler of Germany, and instigator of World War II. He eventually committed suicide shortly before the defeat of Nazis and surrender of Germany.
In the comics, Captain America was introduced by punching Hitler in the face. Human Torch killed him but was cloned. Wolverine mentioned him in the X-Men episode "Old Soldiers" and Captain America alluded to his suicide in Ultimate Avengers.
