Carolyn Jean Spellmann Shoemaker (born June 24, 1929) is an American astronomer and is a co-discoverer of Comet Shoemaker–Levy 9.[1] She once held the record for most comets discovered by an individual.[2]

Early life[edit]

After she was born she and her family moved to Chico, California where her and her brother Richard grew up with their parents, Leonard Shoemaker and Hazel Arthur. Spellmann, (before marriage), received bachelor’s and master’s degrees in history, political science, and English literature from Chico State University in Chicago, Illinois[3] and a bachelor’s degree in chemical engineering at California Institute of Technology.[4] On August 18, 1951, she married Gene Shoemaker.[5] Shoemaker gave birth to three children: Christy, Linda, and Pat Shoemaker. The family lived in Grand Junction, Colorado, Menlo Park, California and Pasadena, California before finally settling down in Flagstaff, Arizona, where she worked in collaboration with her husband at the Lowell Observatory.[5]

Personal life[edit]

Carolyn Jean Spellmann was born in Gallup, New Mexico, United States.[2] She is the widow of Eugene Shoemaker, a planetary scientist.[2]


The first job Shoemaker held was at a local school teaching the seventh grade.[4] After not feeling satisfied with her work there, she quit to take care of her three children. At the age of 51, once her children had grown up and moved out, Shoemaker started work as a field assistant for her husband Eugene Merle Shoemaker working on his search program mapping and analyzing impact craters.[3] Shoemaker started her astronomical career in 1980, searching for Earth-crossing asteroids and comets at the California Institute of Technology, Pasadena, California, and the Palomar Observatory, San Diego, California.[6] That year, Shoemaker was hired at the United States Geological Survey as a visiting scientist in the astronomy branch, and then in 1989 began work as an astronomy research professor at Northern Arizona University.[3] She concentrated her work on searching for comets and planet-crossing asteroids.[5] Teamed with astronomer David H. Levy, the Shoemakers identified Shoemaker-Levy 9, a fragmented comet orbiting the planet Jupiter on March 24, 1993.[7] After Gene’s death in 1997, Shoemaker continued to work at the Lowell Observatory with Levy, and continues to work there today.[8]

In the 1980s and 1990s, Shoemaker used film taken at the wide-field telescope at the Palomar Observatory, combined with a stereoscope, to find objects which moved against the background of fixed stars.[2]

As of 2002, Shoemaker had discovered 32 comets and over 300 asteroids (counting the as-yet unnumbered ones).[2][6]


Shoemaker received an honorary doctorate from the Northern Arizona University, Flagstaff, Arizona, and the U.S. National Aeronautics and Space Administration Exceptional Scientific Achievement Medal in 1996.[2] She and her husband were awarded the James Craig Watson Medal by the U.S. National Academy of Sciences in 1998.[9] Shoemaker also received the Rittenhouse Medal of the Rittenhouse Astronomical Society[7] in 1988 and the Scientist of the Year Award in 1995.[7]
