Owen Gingerich is professor emeritus of astronomy and of the history of science at Harvard University and a senior astronomer emeritus at the Smithsonian Astrophysical Observatory. Although trained as an astrophysicist, his interests turned to the history of science as part of his quest to understand how science works, particularly in comparison with spiritual knowledge. Dr. Gingerich is the co-author of two successive standard models for the solar atmosphere and is a leading authority on the astronomers Nicolaus Copernicus and Johannes Kepler. He has been vice president of the American Philosophical Society and has served as chairman of the U.S. National Committee of the International Astronomical Union, and a councilor of the American Astronomical Society (AAS), for which he helped organize its Historical Astronomy Division (HAD). Awards to Dr. Gingerich include the HAD's Doggett Prize for his contribution to the history of astronomy (2000), the AAS Education Prize (2004), and the Harvard-Radcliffe Phi Beta Kappa Prize for excellence in teaching (1984). He has given two Advent sermons at the National Cathedral. Dr. Gingerich has written over 700 technical or educational articles and reviews. His most recent books are The Book Nobody Read: Chasing the Revolutions of Nicolaus Copernicus (Walker & Co., 2004) and God's Universe (Harvard, 2006). For nearly four decades he taught a core science course at Harvard, “The Astronomical Perspective,” which eventually included a short section on biological evolution. He is now writing, from a historical and Christian perspective, a book on evolution, The Divine Handiwork.
