Donald G. York is the Horace B. Horton
Professor of Astronomy and Astrophysics at the
University of Chicago. An observational cosmologist,
he has focused much of his research on the gas
and dust between galaxies for the clues they provide
to the formation and evolution of the universe.
He was the founding director of the Apache Point
Observatory in Sunspot, New Mexico, serving for
fourteen years, and of the Sloan Digital Sky Survey,
one of the most ambitious collaborative projects
ever undertaken by astronomers. He is also the
founder and co-director of the Chicago Public
Schools/University of Chicago Internet Project.
A graduate of the Massachusetts Institute of Technology,
Dr. York took his Ph.D. in astronomy and astrophysics
at Chicago in 1971. For the next eight years,
he worked on ultraviolet spectra of the interstellar
medium as a research astronomer. Named a senior
research astronomer at Princeton in 1979, he accepted
an associate professorship in astronomy and astrophysics
at Chicago three years later. Promoted to professor
in 1985, he was awarded his present chair in 1992.
Dr. York has lectured on his research throughout
the United States as well as in Australia, Canada,
China, Japan, Russia, Italy, Germany, France,
and England. As a Harlow Shapley Lecturer of the
American Astronomical Society, he lectures at
small colleges across America on cosmology and
on science and religion. He is the author of some
330 scientific papers.
