Owen Gingerich

Owen Gingerich is emeritus professor of astronomy and the history of science at Harvard University and an emeritus senior astronomer at the Smithsonian Astrophysical Observatory. A leading authority on the sixteenth-century Polish cosmologist Nicolaus Copernicus and  the seventeenth-century German astronomer Johannes Kepler, he spent three decades tracking down and examining copies of De revolutionibus
orbium coelestium (On the Revolutions of the Heavenly Spheres)
, the seminal work in which Copernicus first proposed that the Earth is not fixed but revolves around the Sun. His own contributions to theoretical astronomy include work on stellar atmospheres. A member of the American Philosophical Society and the American Academy of Arts and Sciences, he has served as a trustee of the John Templeton Foundation and a member of its board of advisors.
