Alan Sandage too ...
Hi All,
Further to the sad news that we lost Brian Marsden on 18th November, just a few days earlier Alan Sandage, one of the most influential astronomers of the 20th century died on November 13th. Sandage was well known for his work on galaxies, galaxy classification and structure, cosmology and made the first reasonably accurate estimation for the Hubble Constant – in 1958 he revised down Hubble’s own estimate of his constant from 250 km/sec/mpc to 75km/sec/mpc. That estimate is quite close to the currently accepted value of 71.5 km/sec/mpc. Sandage studied under such luminaries as Edwin Hubble himself and also Walter Baade and published over 500 papers during his working career.
Asteroid 9963 Sandage is named for him.
Another sad loss.
Best,
Les D
