In 1923, working with Frederick Saunders, he developed '''Russell–Saunders coupling''' which is also known as [[LS coupling]].<ref>David H.

== Biography ==
Russell was born in 1877 in [[Oyster Bay, New York]]. He studied astronomy at [[Princeton University]], obtaining his [[Bachelor of Arts|B.A.]] in 1897 and his doctorate in 1899, studying under [[Charles Augustus Young]]. From 1903 to 1905, he worked at the [[Cambridge Observatory]] with [[Arthur Robert Hinks]] as a research assistant of the [[Carnegie Institution of Washington|Carnegie Institution]] and came under the strong influence of [[George Darwin]].
 
In November 1908 Russell married Lucy May Cole. They had four children. Their youngest daughter, Margaret, married the astronomer [[Frank K. Edmondson]] in the 1930s.
 
== Published work ==
He co-wrote an influential two-volume textbook in 1927 with [[Raymond Smith Dugan]] and [[John Quincy Stewart]]: ''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. There were two volumes: the first was ''The Solar System'' and the second was ''Astrophysics and Stellar Astronomy''. The textbook popularized the idea that a star's properties (radius, surface temperature, [[luminosity]], etc.)
were largely determined by the star's mass and chemical composition, which became known as the [[Vogt-Russell theorem]]
(including Hermann Vogt who independently discovered the result). Since a star's chemical composition
gradually changes with age (usually in a non-homogeneous fashion), [[stellar evolution]] results.
