Background
</h2>
<p class="article__text">
<a rel="nofollow" class="btn-edit-popup" href="/web/person-edit.html?profileId=3770129§ion=background#general"></a>
Joseph H. Moore was born on September 7, 1878, in Wilmington, Ohio, the only child of John Haines Moore and Mary Ann Haines, distant cousins. John Moore, of Irish descent, was a native of Clinton County, Ohio. He worked successively as a weaver, cabinetmaker, miller, and merchant and during his later years owned and operated a large farm. Mary Moore, of English ancestry, was born in Lancaster County, Pennsylvania. Both were members of the Society of Friends.<br/><br/>Joseph was brought up in that faith and throughout his life attended Quaker meetings whenever possible. The family was in comfortable though not affluent circumstances.

Education
</h2>
<p class="article__text">Moore attended public schools in Wilmington and the local Wilmington College, founded in 1870 by the Society of Friends. He took the classical course, but a class in astronomy in his senior year stirred his interest in scientific research, and after receiving the Bachelor of Arts degree in 1897 he enrolled in the graduate school of the Johns Hopkins University, planning to work under the astronomer Simon Newcomb.<br/><br/>Although he took one graduate course in astronomy, Moore's deficiencies in mathematics and physics forced him to spend most of his first two years in undergraduate courses. By the end of that time the graduate department in astronomy had been discontinued, and he shifted his major to physics, studying under Henry A. Rowland, Joseph S. Ames, and Robert W. Wood. <br/><br/>He received the Doctor of Philosophy degree in 1903 with a dissertation on the fluorescence and absorption spectra of sodium vapor.</p>

Career
</h2>
<p class="article__text">Moore was offered several posts in physics and chose to go to the Lick Observatory of the University of California as an assistant in spectroscopy to the director, William Wallace Campbell. He remained at Lick for more than forty years, becoming assistant director in 1936 and director in 1942. At the Lick Observatory, Moore was first assigned to work in Campbell's extensive and pioneering program of using spectroscopic methods to measure the radial velocities of all the brighter stars, a collaborative project that continued for the next twenty-five years.<br/><br/>During the period 1909 - 1913 he served as astronomer in charge of the observatory's D. O. Mills station in Chile. There, working under conditions that called for exceptional skill and ingenuity, he extended the radial velocity study to include stars of the southern hemisphere. The project culminated in 1928 in the publication, with Campbell, of the Lick catalogue of Radial Velocities of Stars Brighter than Visual Magnitude 5. 51. Moore was solely or in part responsible for several other catalogues of fundamental value in astronomy.<br/><br/>In 1913, with Campbell, he began measuring the velocities and internal motions of the gaseous nebulae. The results, published as "The Spectroscopic Velocities of Bright-Line Nebulae", included all such objects that could be observed with the means then available.<br/><br/>He also prepared and published three catalogues of spectroscopic binaries, the last (1948) with the collaboration of Ferdinand J. Neubauer, and, in 1932, a comprehensive catalogue of all the radical velocities of stars, nebulae, star clusters, and galaxies that had been determined up to that time.<br/><br/>Moore was active in other fields of astronomy. Between 1918 and 1932 he took part in five Lick Observatory expeditions to observe solar eclipses, and was in charge of the last two. His particular interest was in photographing and analyzing the spectrum of the solar corona. With J. F. Chappell, photographer at the Lick Observatory, he prepared a widely used photographic atlas of the moon. He studied the spectra of novae, or temporary stars, including the remarkable southern nova Eta Carinae. He determined the orbits of numerous spectroscopic binaries and, with Donald H. Menzel, the rotation of Uranus and Neptune. <br/><br/>A heart condition required him to leave the altitude of Mount Hamilton in 1945. He moved to Oakland and taught courses in astronomy at the University of California in Berkeley until his retirement in 1948. He died on March 15, 1949, of a coronary occlusion and was buried at Oak Hill Cemetery, San Jose, California.</p>
