Named in memory of Andrew Ellicott Douglass (1867–1962), American astronomer and founder in 1901 of the science of dendrochronology. As Percival Lowell’s {see planet  (1886)} principal assistant from 1894 to 1901, Douglass had investigated observing sites in Arizona and Mexico, and upon joining the faculty of the University of Arizona in Tucson in 1906 he mounted a campaign to bring a major observatory to southern Arizona. Through a gift from Lavinia Steward this effort met success with the completion in 1921 of a 0.9-m telescope, and Douglass served as director of the Steward Observatory until 1937. Having already made a mark in the use of dendrochronology for the dating of archaeological ruins, he then founded and directed until his 91st year the University’s Laboratory for Tree Ring Research.
