Allan R. Sandage, Staff Astronomer Emeritus, The Observatories (Pasadena, CA) Carnegie Institution of Washington, has for half a century been a leader in our observational quest to understand the stars, galaxies and the universe.
Allan R. Sandage has defined the fields of observational cosmology and extragalactic astronomy for most of the last forty years.
Sandage was the first to recognize the existence of quasars without strong radio emission, leading the way to the discovery of some of the most distant objects in the universe.

No "Age of the Universe" Controversy - Per Dr. Allan Sandage by Dean Fletcher Among the untold numbers of amateur astronomers over the country, there may be tens of thousands who have experienced frustration hundreds of times over the years with gunky, and/or light-polluted skies.
Sandage, after his education, worked directly with Edwin Hubble for some years and according to the Encyclopedia Brittannica was the optical discoverer among other things of those intriguing and still-not-understood phenomena called quasers.
Sandage's conclusion is that "there is no crisis in cosmology regarding the time scale as determined from (1) the expansion rate at the present epoch, and (2) the independently known age of the universe determined from stellar expansion...Ó

 Newsweek: Science Finds God
As much as any other 20th-century astronomer, Sandage actually figured it out: his observations of distant stars showed how fast the universe is expanding and how old it is (15 billion years or so).
But through it all Sandage, who says he was "almost a practicing atheist as a boy," was nagged by mysteries whose answers were not to be found in the glittering panoply of supernovas.
Sandage began to despair of answering such questions through reason alone, and so, at 50, he willed himself to accept God.

Sandage went on to investigate the nature of Q, the structural "constant".
Despite having produced an empirical PL relation, Sandage and Tammann had not abandoned the concept of a PLC relation; they identified this 0.5 magnitude scatter with the width of the instability strip.
Sandage and Tammann’s calibration did not signal the end of PLC relations, that of Martin, Warren and Feast (hereafter MWF) (1979) is an excellent example of a PLC calibration from near the close of this, admittedly rather loosely defined, "period".

a 1985 paper by Chip Arp and Allan Sandage, two of the most influential astronomers of their generation.
Allan Sandage has worked for decades to determine some of the fundamental parameters of the universe in which we live, such as its age, rate of expansion, and whether it will live forever).
By analyzing the spectra of the knots (their brightness at many different wavelengths) Arp and Sandage were able to show that the knots were probably not foreground stars.

 Science -- Finkbeiner 284 (5419): 1438
If--as astronomer Allan Sandage once said--all of cosmology is the search for two numbers, then the search might now be half over.
Sandage, also at the Carnegie Observatories, has spent a distinguished career looking for the value and is holding out for a slightly slower expansion rate.
But another team, led by Sandage with Gustav Tammann of the University of Basel in Switzerland, measured the constant at 55, implying a comfortably old universe and no age crisis.

If anyone can present a good argument why it's wrong, we'll listen.'' Allan Sandage is angry at his astronomical brethren too, but his beef is just the opposite of Lauer's.
For decades, Sandage's results have suggested that the cosmos is 15 billion to 20 billion years old or thereabouts.
If she's right and Sandage is wrong, as many cosmic handicappers are betting, then the age crisis won't go away without some fundamental change in the way astronomers understand the cosmos.

From this, Sandage estimated of the age of the Universe (T) to be 19.2 billion years [T = 2/3 x (1/H) ].
These calculations have changed through the years and now, H=~ 75 (T=12.9 billion years) is more generally accepted.

 A NEW VALUE FOR THE HUBBLE CONSTANT   (Site not responding. Last check: 2007-09-10)
Allan Sandage of the Carnegie Institution and his colleagues have used the Hubble Space Telescope to observe 27 cepheids in galaxy IC4182; the reliable relation between the cepheids' variability rate and intrinsic brightness gives a value of 16 million miles to IC4182.
This allowed Sandage to calculate the intrinsic brightness of a type-IA supernova also residing in IC4182; this brightness could be compared to that of similar supernovas in more distant galaxies.
This distance-finding technique results in a value of 45 for the Hubble constant and an age for the universe of at least 15 billion years.

Allan Rex Sandage is considered the greatest observational cosmologist in the world.
As former journalist Lee Strobel writes in his book The Case for a Creator, Sandage had “deciphered the secrets of the stars, plumbed the mysteries of quasars,” and quantified the expansion of the universe.
While discussing the Big Bang and its philosophical implications, Sandage announced that he had become a Christian—and that it was science that drove him to his beliefs.

When Hubble died, in 1953, Sandage inherited the great astronomer's long-term project to find Hubble's constant, a number astronomers would later use to determine the age of the universe (which Sandage now estimates to be about 15 billion years).
Yet Sandage has never wavered from his first love, the stars.
