American astronomer
Raymond Smith Dugan (May 30, 1878 – August 31, 1940) was an American astronomer and discoverer of minor planets.[2] His parents were Jeremiah Welby and Mary Evelyn Smith and he was born in Montague in the U.S. state of Massachusetts.[3]
His undergraduate and Masters was from Amherst College in Massachusetts in 1899 and 1902. Dugan then received his Ph.D. dissertation in 1905 at the Landessternwarte Heidelberg-Königstuhl (Königstuhl Observatory, near Heidelberg) at the University of Heidelberg.[4]
At the time, the observatory at Heidelberg was a center of asteroid discovery under Max Wolf. During Dugan's stay there, he discovered 16 asteroids between 1902 and 1904, notably including 511 Davida.[1][5]
He was employed by Princeton University as an instructor (1905–1908), assistant professor (1908–1920), and professor (1920—). He married Annette Rumford in 1909.
Dugan co-wrote an influential two-volume textbook in 1927 with Henry Norris Russell and John Quincy Stewart called Astronomy: A Revision of Young’s Manual of Astronomy (Ginn & Co., Boston, 1926–27, 1938, 1945). This became the standard astronomy textbook for about two decades.[citation needed] There are two volumes: the first is The Solar System and the second is Astrophysics and Stellar Astronomy.
Dugan was elected to the American Philosophical Society in 1931.[6] The lunar crater Dugan and the main-belt asteroid 2772 Dugan are named in his honour.[2]
