About Joel Stebbins
- Joel Stebbins (July 30, 1878 – March 16, 1966) was an American astronomer who pioneered photoelectric photometry in astronomy.
- He was director of the University of Illinois Observatory from 1903 to 1922 where he performed innovative work with the selenium cell.
- In 1922 he became director of the Washburn Observatory at the University of Wisconsin–Madison where he remained until 1948.
- After 1948, Stebbins continued his research at Lick Observatory until his final retirement in 1958. Stebbins brought photoelectric photometry from its infancy in the early 1900s to a mature technique by the 1950s, when it succeeded photography as the primary method of photometry.
- He used the new technique to investigate eclipsing binaries, the reddening of starlight by interstellar dust, colors of galaxies, and variable stars.
