2000 Gruber Cosmology Prize Citation

Allan Sandage, Staff Astronomer Emeritus, The Observatories (Pasadena, CA) Carnegie Institution of Washington, has for half a century been a leader in our observational quest to understand the stars, galaxies and the universe. This prize recognizes his relentless pursuit of the true values of the Hubble constant, the deceleration parameter, and the age of the universe.

Phillip Peebles, Albert Einstein Professor of Science, Princeton University, has made profound contributions to our knowledge of the physical processes that have shaped the structure of our universe. Over more than three decades he has, with rigor and imagination, advanced our understanding of phenomena which range from the creation of the lightest elements to the formation of galaxies and the cosmic distribution of matter and radiation.
