Science Accomplishments
Throughout the 1950s and 1980s Sandage was regarded as the best observational cosmologist, making contributions to all aspects of the cosmological distance scale, ranging from calibrators within our own Milky Way Galaxy, to cosmologically distant galaxies.

His research resulted in a doubling of the estimated age of the universe (from 1.8 to 3.6 billion years).

Sandage performed photometric studies of globular clusters, and calculated their age to be at least 25 billion years. This led him to speculate that the universe did not merely expand, but actually expanded and contracted with a period of 80 billion years
Education
He graduated from the University of Illinois in 1948. In 1953 he received a Ph D from the California Institute of Technology
