>> ...but when it comes to personal life, he was just an asshole

I don't know about you, but physical abuse (e.g. choking his spouse if she interrupted him while he worked) goes way beyond asshole territory IMHO. We're talking about someone who was essentially an incredibly cruel, if not monstrous person.

But what generally happens with these types of things is that history tends to treat famous men very kindly and overlook or even completely erase their dark sides. That is indeed what has happened with Feynman.
