This is cracking me up - long shot that you can help based on so little info but might as well ask!
I remember reading about a brilliant mathematician whose father was a carpenter (I think - some kind of trade anyway). He loved maths, studied it all the time, taught himself all sorts of maths and went on to do great things.
That's it! I can't remember any more. Like I said, very long shot, but if you know who I'm talking about please tell me!! 😊
