About Charles Augustus Young
Charles Augustus Young (December 15, 1834 – January 4, 1908) one of the foremost solar spectroscopist astronomers in the United States, died of pneumonia after a brief illness, at his home in Hanover, New Hampshire, on 4 January 1908. He observed solar eclipses and worked on spectroscopy of the Sun. Graduated from Dartmouth, he later became a professor there in 1865, remaining until 1877 when he went to Princeton.
He was a successful educator who wrote a popular and widely-used series of astronomy textbooks, including Manual of Astronomy. Many years later 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.
