Owen Jay Gingerich (/ˈɡɪŋɡərɪtʃ/; born 1930) is professor emeritus of astronomy and of the history of science at Harvard University and a senior astronomer emeritus at the Smithsonian Astrophysical Observatory. In addition to his research and teaching, he has written many books on the history of astronomy.
Gingerich is also a member of the American Academy of Arts and Sciences, the American Philosophical Society, and the International Academy of the History of Science. A committed Christian, he has been active in the American Scientific Affiliation, a society of evangelical scientists. He has served on the board of trustees of the Templeton Foundation.
Gingerich was born to a Mennonite family in Washington, Iowa, but was raised on the prairies of Kansas where he first became interested in astronomy. His father, Melvin Gingerich, taught at Bethel College in North Newton, Kansas, from 1941 to 1947, when he took a job at Goshen College in Indiana. He travelled to Poland in 1946 as a seagoing cowboy. When his family relocated, Owen Gingerich began attending Goshen College without having graduated from high school, having just completed his junior year. He continued his studies at Harvard University. In 2004, Newton High School awarded him an honorary high school diploma.
