Vera Rubin was quite an astronomer [1] both in her discoveries like the rotation of galaxies (confirming dark matter), and for being a trailblazer for women in astronomy. I love reading bios of people like this. Glad to see her get recognized with such a great observatory [2] continuing her legacy of studying dark matter.

Fritz Zwicky discovered Dark Matter. Rubin thought she discovered Dark Matter, because she wasn't aware of Zwicky's paper written in German many years before Rubin's paper.

edit: I have a PhD in Astronomy, with a focus on Dark Matter, and I measured rotation curves of galaxies myself.

Wikipedia link for those who, like me, where unfamiliar: https://en.wikipedia.org/wiki/Fritz_Zwicky

I have not read anywhere that she discovered Dark Matter but rather that her observations confirmed its presence as “first proposed by Fritz Zwicky in 1933 but rejected by most scientists.”
