I don't think he was especially brainy or above average in intelligence. He may have went to school as a kid but I really doubt he would've attended Uni or went to college (assuming they had those back then). Apart from how he sliced Annie open there's not one thing that indicates to him being skilled or intelligent in any way other than you're average person.
