Did anyone else know of Richard Feynman's as a giant name in physics, so many contributions and insights, and then find themselves surprised when first hearing

Did anyone else know of Richard Feynman's as a giant name in physics, so many contributions and insights, and then find themselves surprised when first hearing him speak? One day I was watching this guy on YouTube whose job is walking around selling peanuts at a baseball stadium in Chicago, blue collar local accent in full tow. He starts to chatter about in a casual, simple, mundane way about how his day was going. Except, it wasn't a baseball peanut barker, it was a Nobel prize winning particle physicist, it was Feynman. If he would have sold peanuts part time at a baseball stadium for five years maybe no one would have noticed anything out of place. It's not a criticism, it only raised his rank on my list of admired scientists. I found the humility, his passion for making hard things as easy to understand as possible, his ability to just be a regular guy around people, really a beautiful thing.
