Dr. Rubin stood as a constant reminder of the sexism that is still such a problem in many scientific fields. There were petitions and protests and demands that she be awarded the Nobel Prize in Physics for her discoveries, and now she never will be.
This is how the autobiographical article she wrote for the 2011 Annual Review of Astronomy and Astrophysics begins:
My life has been an interesting voyage. I became an astronomer because I could not imagine living on Earth and not trying to understand how the Universe works. My scientific career has revolved around observing the motions of stars within galaxies and the motions of galaxies within the Universe. In 1965, if you were very lucky and interested in using telescopes, you could walk into a research laboratory that was building instruments that reduced exposure times by a factor of 10 and end up making remarkable discoveries. Women generally required more luck and perseverance than men did.
