He threatened suicide if a woman wouldn't date him. That's abusive manipulation.
He, unsolicitedly hands out 'pleasure cards' to women at conferences. That's harassment: Conferences are a interest and professional environment; they're not Tinder.
Having a bed in his office at MIT is creepy as hell. Inviting woman at MIT into his office would hence be harassment.
Women at MIT had to keep plants in their offices to ward him off. Ward off his persistent, unwanted, sexual advances. That's him causing harassment.
Those cards said "Sharing good books, good food and exotic music and dance - tender embraces - unusual sense of humor." Handing out such calling cards seems to only be classified as harassment if the man is fat.
That depends. Do you wear shirts while on teleconferences, and what art do people get subjected to?
I will also require your taste in literature, boxers or briefs, tube socks with/without the colored stripes or those ankle socks,
and toilets or bidets to make a final determination.
It seems he said some things that one might disagree with which is fair enough but saying it’s sexual harassment seems like a stretch IMO.
