Tycho Brahe

Noted astronomer Tycho Brahe once had most of his nose chopped off by a broadsword during a duel with a rival mathematician. He lived on his own private island in a massive castle complete with trap doors, an army of astronomer henchmen, and a dungeon where he could extrajudicially imprison anyone who pissed him off whenever he wanted. He had a pet moose that got drunk at parties (so much so that one night the moose was so drunk it fell down stairs to its death). He was best friends with a psychic dwarf who lived under his dining room table. Brahe accurately predicted the cosmic trajectories of over 700 stars despite the fact that he was performing his observations with his naked eye because he was working before the invention of the telescope.
