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]].
He returned to Princeton to become an instructor in astronomy (1905–1908), assistant professor (1908–1911), professor (1911–1927) and research professor (1927–1947). He was also the director of the Princeton University Observatory from 1912 to 1947. He died in [[Princeton, New Jersey]] in 1957 at the age of 79.<ref>{{cite book |title=The Historical Development of Quantum Theory, Vol. 1, Part 2 |last=Mehra |first=Jagdish |coauthors= Helmut Rechenberg |year=2001 |publisher=Springer |page=686 |url=http://books.google.com/books?id=8tUVMSsC9wAC}}</ref>
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.
