If you could meet anyone in history, who would it be?

Name 1-5 people you want to meet from now or the past. For me it would be Adolf Hitler, I find him very intriguing most people find that odd, however of a man he was I find him interesting. Another person from history I'd like to meet is Sir Winston Churchill I'd also like to meet three of my heroes, Lt Gen. Romeo Dallaire, Brian Steidle and Rick O'Barry.
