He earned his Ph.D at the [[University of California]]. He was director of [[University of Illinois at Urbana-Champaign|University of Illinois]] observatory from 1903 to 1922 and the [[Washburn Observatory]] at the [[University of Wisconsin-Madison]] from 1922 to 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. Stebbins used the new technique to investigate [[eclipsing binaries]], the reddening of starlight by [[interstellar dust]], colors of [[galaxies]], and [[variable stars]]. ==Honors== '''Awards''' *[[Rumford Prize]] of the [[American Academy of Arts and Sciences]] (1913) *[[Henry Draper Medal]] of the [[United States National Academy of Sciences|National Academy of Sciences]] (1915) *[[Bruce Medal]] of the [[Astronomical Society of the Pacific]] (1941) *[[Gold Medal of the Royal Astronomical Society]] (1950) *[[Henry Norris Russell Lectureship]] of the [[American Astronomical Society]] (1956) '''Named after him''' *[[Stebbins (crater)|Stebbins crater]] on the [[Moon]] *[[Asteroid]] [[2300 Stebbins]] ==See also== *[[University of Illinois Observatory]] ==References== {{Unreferenced|date=June 2008}} {{DEFAULTSORT:Stebbins, Joel}} [[Category:1878 births]] [[Category:1966 deaths]] [[Category:American astronomers]] [[de:Joel Stebbins]] [[fr:Joel Stebbins]] [[ja:ジョエル・ステビンス]]
