Meanwhile, author Isaac Asimov’s proclivity for groping women was so widely known that in 1961, the chair of Chicon III wrote a letter inviting him to give a lecture on “The Power of Posterior Pinching.”
I had never heard this about Asimov so it was a little shocking. I did some searching to see if I could find some other references, and I found the following article "Isaac Asimov Was Kind of a Douchebag (To Women)":
... Asimov was well known for his penchant for goosing women
Beyond that I can't find any solid references to that behavior, which is kind of at odds with his more progressive political views. That makes me wonder if this true or a rumor. I could see it being true, who knows what any writer does during their actual life and times were different and all that, but perhaps it's just an unsubstantiated rumor.
Was Isaac Asimov notorious for pinching women's behinds?
