| biography:
| Astronomer, born in Streator, Illinois, USA. In 1930, while studying for his bachelor's degree at the Lowell Observatory in Flagstaff, AZ, he found the ninth planet, Pluto, the existence of which had been predicted by Percival Lowell. He went on to discover a globular star cluster, hundreds of asteroids, and a supercluster of galaxies. After periods at Arizona State College (1943–5), the University of California, Los Angeles (1945–6), and the White Sands Missile Range (1946–51), he settled at New Mexico State University, where he concentrated on studying the planet Mars. |
