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]
