He was a successful educator who wrote a popular and widely used series of astronomy textbooks, including Manual of Astronomy. In 1927, when Henry Norris Russell, Raymond Smith Dugan and John Quincy Stewart wrote their own two-volume textbook, they entitled it Astronomy: A Revision of Young’s Manual of Astronomy.
