Russell, Henry Norris | Determinations of Stellar Parallax
First edition, first impression. A very attractive copy of this key work on stellar parallax which formed the basis for the Hertzsprung-Russell diagram, one of the most important graphs in stellar astrophysics, and which laid the groundwork for the modern method of determining stars’ magnitude and understanding their life cycles.
Henry Norris Russell (1877-1957), who worked at both Princeton and Cambridge, was described by astrophysicist F. J. M. Stratton as, "the most eminent and versatile theoretical astrophysicist in the United States if not in the world"."Russell pioneered in the use of atomic physics for the analysis of the stars and thus played a principal part in laying the foundations of present-day astrophysics. He analyzed the physical conditions and chemical compositions of stellar atmospheres and evaluated the relative abundance of the elements. His assertion of the overwhelming abundance of hydrogen was accepted, after prolonged controversy, as one of the basic facts of cosmology" (Princeton University biography).
