Well first off, 120 is very smart. I don't see how saying that suggests he wasn't highly intelligent. My only point is that there's a reasonable case to be made that his contributions had more to do with how he acted, his personality, his drive, etc., than just with being born smarter than everyone. I really dislike the notion of "genius"; because I think it gives people an excuse to never develop themselves or to be happy with whatever intellectual plateau they've reached. Whenever I hear someone say "well so and so was a genius" I always feel like there's an unstated but implicit message of "so why bother?"
