Life and career

Born in Paris, he had an early interest in amateur astronomy and received his undergraduate degree in 1939 at the Sorbonne in that city. After military service in World War II, he resumed his pursuit of astronomy.

Fluent in English, he spent 1949–51 in England, 1951–57 in Australia, the latter at Mount Stromlo Observatory, 1957–58 at Lowell Observatory in Arizona and 1958–60 at Harvard. In 1960 he was appointed to the University of Texas at Austin, where he spent the rest of his career. He died of a heart attack in his home in Austin at the age of 77.[2]

He specialized in the study of galaxies and co-authored the Third Reference Catalogue of Bright Galaxies with his wife Antoinette (1921-1987), a fellow UT Austin astronomer and lifelong collaborator.[3] His specialty included reanalyzing Hubble and Sandage's galaxy atlas and recomputing the distance measurements utilizing a method of averaging many different kinds of metrics such as luminosity, the diameters of ring galaxies, brightest star clusters, etc., in a method he called "spreading the risks." During the 1950s he promoted the idea that galactic clusters are grouped into superclusters.[2]

The de Vaucouleurs modified Hubble sequence is a widely used variant of the standard Hubble sequence.

De Vaucouleurs was awarded the Henry Norris Russell Lectureship by the American Astronomical Society in 1988. He was awarded the Prix Jules Janssen of the Société astronomique de France (Astronomical Society of France) in the same year.

Antoinette de Vaucouleurs his wife and longtime collaborator, together produced 400 research and technical papers, 20 books and 100 articles for laymen.[4]
