Sandra Faber (b. 1944) is an astronomer who has made significant contributions and discoveries to the field throughout her career. Her research led to the discovery of links between the brightness of galaxies and the speed of the starts within them, and to the Faber-Jackson relation which bears her name. She also had a vital part in the design of the Keck telescopes in Hawaii.
She earned her PhD in Optical Observational Astronomy from the University of Harvard in 1972. She then became the first woman to work for the Lick Observatory in Santa Cruz, as an Assistant Professor. She was the principal investigator of the Nuker Team, which searched for supermassive black holes using the Hubble Telescope.
