4. Johann Georg Faust
As the legend goes, Doctor Johann Georg Faust was an alchemist and astrologer who lived in Germany during the early 1500s. He wanted to be the smartest man in the world, and enjoy as many earthly pleasures as he possibly could while he was still alive. He made a deal with a demon called Mephistopheles.
According to records, he sodomized some of his male students, and was generally abusive and mean towards everyone. As a professor, he looked down on everyone else, because he believed that he was far superior. Local priests believed that he was in cahoots with the devil and that his pet dog was actually a demon who could transform in and out of canine form and into a human man servant. It would seem that he truly did believe in magic, because during his lifetime, he published several grimoires, or spell books. In 1540, he was conducting an alchemic experiment, and his laboratory exploded.
