FTP, name this man who organized the 1919 expedition that confirmed the prediction of the relativistic bending of light in a strong gravitational field.
He found that the scattering of electrons was the primary source of the opacity of stars, and the divisor of the inequality for finding a star's maximum luminosity bears his name.  He interpreted Einstein's theory of relativity for the English-speaking public in his Space, Time, and Gravitation, but tarnished his reputation with incessant, misguided critiques of the work of Chandrasekar.
