My black and white and grey digital sketch of Cecilia Payne Gaposchkin. Above it, a citation from her thesis: 'The application of physics in the domain of astronomy constitutes a line of investigation that seems to possess almost unbounded possibilities'. Slightly in the background sketches of the energy levels in the hydrogen atom (orbital co-sketched) and a star with sun spots and loop/protuberances. Name and citation underlines in red, everything else is black and white.

It's only since Cecilia Payne's PhD thesis in 1925, that we know what the stars - and our Sun - are made of: mostly hydrogen.
Her thesis was described as ""the most brilliant PhD thesis ever written in astronomy" and it extremely readable: https://ui.adsabs.harvard.edu/abs/1925PhDT.........1P/abstract
Yet It took until 1956, 10 years before her retirement, for her to become full professor - because women were barred from becoming full professors at Harvard.
