Let me be crystal clear that I am NOT defending Asimov here; he used his fame and was aware that many of the women will not be believed if they spoke out -- and shamelessly took advantage of that.
Combine that with my strictly personal opinion that he could have taken much better care of his looks at least; a good barber and a dentist alone would have gone a long way so he looked a bit less unpleasant, not to mention he could have jogged once a month and still could have been in a better shape...
...but after reading stories about many other authors, well, Asimov looks like a saint in comparison.
Again, not defending the guy. And Heinlein's gullibility also starkly contrasts with his intelligent aura and writing style. Goes to show we all have blind spots, I suppose. A bro club and all that in their case, probably.
