Is there a term for this kind of person?

I’m trying to remember if there’s any name for a person like this. I remember seeing them all the time in cartoons and such.

An older gentleman is usually sitting in a big, leather padded chair in a study or library. He wears a plush robe, usually has a glass of sherry or a pipe. He is an intellectual, sometimes used as a narrator type of person for PBS-type shows.

I know it’s a weird question, but can anyone help me with this? Any sort of descriptive terms or images would be very helpful. Thanks everyone!
