#8: Baby Face Nelson
Baby Face Nelson was a Chicago criminal named Lester Gillis who joined John Dillinger’s bank-robbing crew in 1934. The media gave him his nickname because of his small stature and youthful facial features, though he possessed a highly volatile temper. He earned a reputation for using heavy weaponry against law enforcement. His violent career concluded on November 27, 1934, during a fierce gun battle with federal agents in Barrington, Illinois, where he suffered fatal injuries.
