Thanks to @STEMWomen, who noted on twitter that “Cecelia Payne-Gaposchkin discovered that the sun is mainly composed of hydrogen,”  citing this Facebook page from Astronomy/Astrophysics History and News.

The American Museum of Natural History has an online excerpt about Cecilia Payne from COSMIC HORIZONS: ASTRONOMY AT THE CUTTING EDGE, edited by Steven Soter and Neil deGrasse Tyson, a publication of the New Press. © 2000 American Museum of Natural History.
