James Tiptree Jr. was a pen name used by Alice B. Sheldon to write science fiction. She's known for three things:
1. She was a great writer, especially on topics of gender.
2. By passing as male for so long, she challenged a lot of the assumptions of the SF community about female writers.
3. At the age of 71, struggling with depression and the challenges of caring for an elderly husband with dementia, she killed him and then herself.
At the time, it was generally assumed that Tiptree and her husband had a suicide pact, but there's always been the possibility that her husband didn't explicitly agree to it, and it was a mercy killing.
Four years after her death, in 1991, the James Tiptree Jr. Award was established in her honor.
Fast forward to this year. The John Campbell Award was renamed after a recipient pointed out that John Campbell opposed her participation in Science Fiction. John Campbell was an editor who helped establish SF as a field, but he was also opposed to women, non-white, and Jewish writers, so Ms. Ng would have been doubly excluded.
As a result, disabled activists on Twitter began calling for the James Tiptree Jr. Award to be renamed, because killing her invalid husband was ablist. Three days ago, the award announced that within the next month, they'd be changing the name. The article I linked says that as an able-bodied person she can't argue with them.
So let me say this: as a disabled person, I'm appalled. Tiptree herself was disabled, both physically and mentally through depression. Renaming the award because a few Twitter activists think she was ablist marginalized her own struggles.
Moreover, while there's really no obvious connection between John Campbell and an award for new writers, James Tiptree is the most logical person to name an award about fiction that explores issues of gender. There are a few other writers whose writing on gender was similarly impactful, most notably Ursula K. LeGuin (who recently died, as it happens; if they're going to renamed it, I hope they rename it after her). But, again, Tiptree, by passing as a man, did more to pave the way for the acceptance of women in science fiction than any writer could have done simply by writing.
