Vera Rubin
Measured galaxy rotation and found they spin far too fast for the visible matter in them, which is the best evidence there is for dark matter. She never got the Nobel.
Vera Florence Cooper Rubin 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.
