“Never heard of Cecilia Payne?
Now you have”

Cecilia Payne-Gaposchkin's 1925 thesis that the sun was composed mostly of hydrogen and helium was rejected by a professor who called it "impossible". Years later, the man who rejected it realized she was in fact right, but he was credited with the discovery for decades. A prominent astronomer called her discovery "the most brilliant PhD thesis
ever written in #astronomy".
