life and career
Sandage studied at the University of Illinois and at the California Institute of Technology , where he studied stellar evolution as a student of Walter Baade from 1949 . In 1953 he received his doctorate with a thesis on the globular cluster Messier 3 . Since 1952 he worked at the Mount Wilson and Palomar Observatory (now the Observatory of the Carnegie Institution of Washington ) in Pasadena .
Sandage made a large number of observations with the aim of determining the value of Hubble's constant . He continued a program initiated by Hubble, whose former assistant Sandage was, after his death at the Palomar Observatory. In the 1970s and 80s he and Gustav Tammann were among the proponents of relatively low values for the Hubble constant.
In 1960 he discovered the visible counterpart of a radio source that was later identified as a quasar . He also discovered an asteroid , and two comets have also been named Sandage. He is the author of the Hubble Atlas of Galaxies and the revised version of the Shapley-Ames Catalog of Galaxies.
