Elizabeth “Pat” Roemer was born in Oakland, California on September 4, 1929. She graduated from the University of California, Berkeley with a B.A. in astronomy, and followed that with a Ph.D. in 1955. To finance her tuition she taught classes at local public schools.

After completing her degree, she worked as an assistant astronomer at the University of Chicago, researching at their Yerkes Observatory. Her next job was as an astronomer at the US Naval Observatory in Flagstaff, Arizona.

Then in 1966 Roemer was hired by the University of Arizona as an associate professor in the Lunar and Planetary Laboratory. Three years later she was promoted to full professor. Though remaining as a faculty member there, in 1980 also became an astronomer at Steward Observatory in Tucson.

Roemer's special expertise was the detection of comets, though she also discovered the two main-belt asteroids. During her career she also detected 79 returning short period comets and computed many orbits for comets and minor planets. Over a period of 25 years, she took an extensive set of photographic plates of comets, attempting to get consistent data for the magnitudes of the comet nuclei. Her observations led to numerous significant cometary discoveries.
Besides her research, Roemer also served on astronomical commissions and organizations. She also received numerous awards for her groundbreaking work in astronomy.
