One aspect of this is to look at the ways that history is being rewritten now from original materials. All of the -isms of the 1900's painted a picture of straight, white (male) Captains of Industry paving a way to the future, and in revisiting the source materials we are discovering that this image paved over a lot of people that were doing a lot of heavy lifting.

History is full of assistants, spinsters and confirmed bachelors whose stories are being re-told now from diaries and correspondence letters that have been family heirlooms for generations. You can't trust the contemporary reports as accurate, because they have a different agenda than we do 20, 40, 100 years in the future. We only knew of Marie Curie within her own lifetime, less because her work was so profound, but because she had a husband in her own field who conspired with her to subvert a system that didn't want to give her standing. A partner outside your field can't do much for you, and a more selfish collaborator wouldn't.

Who knows what polite fictions are being told about people now that will be reframed by our grandchildren, assuming that scholars can find any of it. If I had to guess it will be neurodiversity. Probably/hopefully doing away with the Tortured Genius trope.
