Newton didn’t have a wife. He had other issues including regularly having nervous breakdowns, wanting anyone who steals something to be summarily executed, and believing in alchemy. By all accounts not a very nice guy but a total genius.
and most of our founding fathers cultivated and used various (now illegal) drugs.
Newton also used and abused his position as President of the Royal Society to discredit and slander his literary and scientific rivals. (He would have called them enemies.)
Not a nice man at all.
