Jerome Kristian

Jerome "Jerry" Kristian (born June 5, 1933 in Milwaukee, d. June 22, 1996 in Ventura County, California) was a theoretical and observational cosmologist, and the first to provide observational evidence of quasar host galaxies.

Kristian began his career in theoretical cosmology but transitioned into observation while working at the Mount Wilson Observatory in the 1960s and 1970s. He helped to pioneer the observational study of pulsars and quasars and participated in the development of the Hubble Space Telescope. He was the first to provide observational support for the now widely accepted theory that quasars are supermassive black holes at the center of distant galaxies. Provided by Wikipedia
