After studies at the Universities of Nebraska and Wisconsin, Joel Stebbins earned the third Ph.D. in astronomy granted by the University of California. He directed the University of Illinois Observatory from 1903 to 1922 and the University of Wisconsins Washburn Observatory from 1922 to 1948, then spent another decade on research at the Lick Observatory. Starting in 1907 with selenium cells so insensitive they could barely detect the moon, Stebbins developed photoelectric photometry to the point where it succeeded photography as the photometric standard. He and his colleagues, especially Albert Whitford, used the new technique to investigate eclipsing binaries, the reddening of starlight by interstellar dust, colors of galaxies, all kinds of variable stars, and the sun.
