Vera Florence Cooper Rubin (/ˈruːbɪn/; July 23, 1928 – December 25, 2016) was an American astronomer who pioneered work on galaxy rotation rates. She uncovered the discrepancy between the predicted and observed angular motion of galaxies by studying galactic rotation curves, the first evidence for the galaxy rotation problem, one key piece of evidence for dark matter. Measurements by other astronomers using 21 centimeter hydrogen line radio telescopes clinched the case.
