Henry Norris Russell (October 25, 1877 – February 18, 1957) was a US astronomer who, along with Ejnar Hertzsprung, developed the Hertzsprung-Russell diagram (1910).
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.
Russell received the Gold Medal of the Royal Astronomical Society in 1921 and the Bruce Medal in 1925. The Henry Norris Russell Lectureship of the American Astronomical Society is named in his honor.
Russell crater on the Moon and a crater on Mars are named after him.
