I actually had an endocrinologist who interned with John Money and was horrified by his actions.

Money's main failure was his belief that gender is more or less exclusively a social constuct. Gender roles certainly are, but one's innate sense of their own gender is not.

Anyway, it's pretty easy to look him up: https://en.wikipedia.org/wiki/John_Money

Sorry, I mean a bibliography of research into SRS across the past 70 years.

I'm particularly interested in pre-1977 research that Steinem would have had access to.

In short I, want to use my annoyance at her non-apology apology to fuel my education in the history of trans research. :)

Sadly no, it's mostly synthesis from reading a lot of articles and twitter accounts like Christa Peterson's.
