One of the most famous pirates is Blackbeard. His real name is Edward Teach, and he went around frightening people into giving him money and suchlike. Despite having a reputation for being a bit of a troublemaker, there is no record of him actually murdering any of his prisoners. However, he apparently walked around with lit fuses on his hat. He also had a peg leg due to losing one of the legs through diabetes.
