To-day's GUARDIAN carries an obituary to the distinguished
astronomer, Allan Sandage, who died aged 84 on November 13, 2010. Sandage was born in Iowa and studied physics and philosophy at the University of Illinois, graduating in 1948. He took a PhD in astronomy at Caltech in 1953 and joined the Carnegie Observatories in Pasadena, California, in 1952.
Sandage studied under Walter Baade ( who predicted neutron stars ) and became Hubble's assistant.
In his many contributions to modern astronomy, Sandage took the first spectrum of a quasar, and showed that the Universe was at least six times larger than previously thought. He showed how type 1A supernovae could be used as standard beacons to measure great distances.
For his doctoral thesis, Sandage studied the stars in the globular cluster M3 and the RR Lyrae variable stars it contains. It was the first step in measuring the true scale of the Universe. He was a foreign member of the Royal Society.
