Who are some successful people that were also very strange?

I was listening to an interview with Michael Lewis, and he was trying to say that Sam Bankman-Fried is some sort of new type of person who can do interesting things but doesn't have people skills. I thought it was ridiculous, because you have people like Isaac Newton, who was an occultist who just happened to create calculus, and Jonathan Swift, who straight up hated people but was a successful author.

Who are some people that are incredibly successful but were very strange people?
