Ugh, not this tired old trope again! Cantor was a troubled man, but he solved the fucking problem, ok? Pitying him because infinity "drove him insane" is like pitying St George's loss to the dragon. It's not just wrong, it's insulting.
My point is that his work didn't drive him mad. This heroic Promethian myth about "dangerous knowledge" is as tiresome as it is false. These Hollywood types need a new stereotype to beat to death.
Ah, OK. I agree. So I guess his madness drove him to work instead.
Actually I live quite close to were Cantor worked. According to Google-Earth I would have to drive for 1h.
