Biography
Allan Sandage (1926–2010) was an astronomer or scientist associated with United States. Refined the extragalactic distance scale and observational cosmology using galaxies, Cepheids and supernovae. In this library, the biography is linked to Cosmic distance ladder, Hubble–Lemaître expansion so the historical contribution can be read beside the modern scientific concepts it influenced.
