Who founded MGM, RKO, Paramount, and 20th Century Fox?

Factual Questions
1

I’m writing a paper on the five major movie studios during the golden age of Hollywood. For sure, Warner Bros. was founded by four people: Harry Warner, Albert Warner, Sam Warner, and Jack Warner. But I don’t know about the other four golden age movie studios. I’ve read conflicting information regarding who founded what. So, I was wondering, if anyone knows the facts. So, I’ll ask away:

  1. Who founded MGM?
  2. Who founded Paramount?
  3. Who founded RKO?
  4. Who founded 20th Century Fox?

Come on, don’t be so hard on the guy. Do you think there’s just, like, a big building full of “books” somewhere that he can just go to? Maybe he can get there in his flying rocket car.
