I’m a little fuzzy on the exact “Rachel Wilson” episode you mean, but in that conversation the key 20th‑century feminist figures that come up are Camille Paglia (she’s mentioned explicitly as a major feminist voice, and as someone critical of a lot of modern institutional feminism). Beyond that, the clip doesn’t actually list a clean roll-call of “key feminist figures” from the 20th century—more like it talks about types of feminists and how media/academia elevates certain ones. If you tell me the episode number or share a longer excerpt, I can pin down the other names they mention.
