To say he was a generally great guy really overlooks how awful he was to women. He was no doubt brilliant, but he had some very serious character flaws. And unfortunately, he had an echo chamber of peers and a rockstar celebrity status that only worked to reinforce his shitty behavior and backwards views. It’s not super uncommon for brilliant people to be absolutely nightmares on a personal level. Imagine being an absolutely brilliant scientist that gets married only to be completely forbidden from science and the things you love, and then reduced to being a maid for a madman with tons of insanely particular demands.
