I feel like his womanizing behavior was bad and that it was also somehow wrapped up in his attention seeking and other self promoting drives that made him so well known. I don't think it should be hidden.
I am really tired of dirt being brought up each time a discussion of a renowned figure is happening. It obviously detracts from the inspiration or immersion people are trying to derive from bringing up those renowned figures. They are intentionally focusing on the positive aspects, and those who are bringing the garbage up are intentionally detracting from it.
You think there's a problem reminding readers that venerated people aren't good role models? Why? Why not strive to be better than them, intentionally moving past their flaws?
I think that attitude would be great, but that isn't what I see happening. There is a widespread movement to cancel basically all famous historical figures, and dismiss the value of their work along with discrediting their personalities. It's frustrating to see, since many of these people were really inspiring to me as a kid, making me want to be a scientist/engineer myself.
Mr Feynman is well known (among other) for his work in the field of quantum electrodynamic theory (for which he won the Nobel price), his diagrams, his lectures and his work in the commission investigating the challenger catastrophe.
When it comes to how we was self promoting, I think it's fair to look at his autobiography (edit: autobiographical anecdotes is probably a better description of the book) (Surely You're Joking Mr Feynman). In which he describes his own redpillish behavior towards women, and brags about how he would troll waitresses by purposely setting up time bomb messes for them to cleanup.
