Allan Rex Sandage
1975 Bruce Medalist
Date of Birth:
Date of Death:
The son of the nation’s first professor of advertising, Allan Sandage studied two years at Miami University of Ohio, served two years in the U.S. Navy during World War II, and then finished his bachelor's degree in physics at the University of Illinois in 1948. He then became one of the first graduate students in astronomy at the California Institute of Technology, where he earned his doctorate under Walter Baade in 1953. From 1952 until his death (emeritus after 1997) he was on the staff of the Mt. Wilson and Palomar Observatories (now the Observatories of the Carnegie Institution for Science), where he began as a graduate student assistant to Edwin P. Hubble. His research was in stellar astronomy and observational cosmology. With Martin Schwarzschild he determined ages and evolution of globular clusters in order to obtain the ages of the oldest objects known. He calibrated all of the “standard candles” to determine distances of remote galaxies and several times presented (often with Gustav Tammann) revised estimates of the value of the Hubble constant. After nearly half a century of observing with the Hale telescope on Palomar Mountain, he used the Hubble Space Telescope to determine distances to galaxies using Cepheid variable stars. In the controversy over the value of the Hubble constant, Sandage and Tammann were strong proponents of a relatively small value of the constant, implying a relatively large, old universe. Sandage found the first optical counterpart to a radio source that would later be identified as a quasar, and he discovered many more, including the radio-quiet ones. He published photographic atlases of galaxies and many historical reviews, including a centennial history of the Mt. Wilson Observatory.
