Named in honor of Carolyn Spellmann Shoemaker (born 1929-06-24; died 2021-08-13), comet and asteroid discoverer. Shoemaker began searching for asteroids in 1980, using plates taken at the U.K. Schmidt Telescope at Siding Spring. She helped develop a new photographic survey program using the 0.46-m Schmidt camera at Palomar Mountain and a newly designed stereomicroscope, which greatly increased the efficiency of film scanning.

Named in honor of Leif J. Robinson, editor of ’Sky and Telescope’. Robinson’s career as an observer began with a series of planetary drawings and observations of the rapidly changing variable stars in the Orion Nebula. He worked at the Griffith Planetarium in Los Angeles before joining the staff of the magazine in 1962 as an editorial assistant, and he succeeded the late Joseph Ashbrook as editor in 1980.

Named in memory of Harold Spencer Jones (1890-1960), successively astronomical assistant at the Royal Greenwich Observatory, H.M. astronomer at the Cape of Good Hope, and Astronomer Royal (1933-1955).  He also served as president of the IAU (1945-1948).  His work was devoted to fundamental positional astronomy, and he conclusively demonstrated that the small residuals in the apparent motions of the planets were due to the irregular rotation of the earth.

Named in memory of Walter Sydney Adams (1876-1956), whose spectroscopic studies of sunspots and stars led to the discovery, with A. Kohlschutter, of a spectroscopic method for determining stellar distances, the relative intensities of spectral lines being used to determine absolute magnitudes of both giant and main-sequence stars.  Adams identified Sirius B as the first white-dwarf star known, and his measurement of its gravitational redshift was taken as confirming evidence for the general theory of relativity.

Named in memory of Ching-Sung Yu (1897-1978), Chinese-American astrophysicist, whose spectrophotometric measurements of 91 stars at the Lick Observatory in the early 1920s represented a milestone in research on stellar energy distribution.  After returning to China he established the Purple Mountain Observatory and served as its first director.  He also developed the site of what is now the Yunnan Observatory, was director of the Academia Sinica’s Institute of Astronomy and president of the Chinese Astronomical Society.
