Hmm, that's a really good question. I don't really know who my absolute favourite is, but I've been more or less fascinated by the following:

- King Henry VIII and his wives
- Adolf Hitler
- Tsar Nicholas the 2nd
- Marie Antoinette
- Homer (mostly his stories, though)
- Jeanne D'arc (sp?)
- Van Gogh
- Leonardo Da Vinci


... I'm sure there are more, but those were the ones I could think of.
