Edwin Charles Krupp (born November 18, 1944) is an American astronomer, researcher, author, and popularizer of science. He is also known as Ed or E.C. He is an internationally recognized expert in the field of archaeoastronomy, the study of how ancient cultures viewed the sky and how those views affected their cultures. He has taught at the college level, as a planetarium lecturer, and in various documentary films. He has been the director of the Griffith Observatory in Los Angeles since first taking over the position in 1974 after the departure of the previous director, William J. Kaufmann III. His writings include science papers and journal articles, astronomy magazine articles, books on astronomy and archaeoastronomy for adults, and books explaining sky phenomena and astronomy to children.

Krupp is a member of the American Astronomical Society and the International Astronomical Union, and has served in several divisions and commissions of both organizations. He is also a fellow of the Committee for Skeptical Inquiry and a member of that organization's Council for Media Integrity.
Edwin Charles Krupp was born in Chicago, Illinois, on November 18, 1944 where as a child his parents took him to many of the local museums. In 1956 the family moved to Los Angeles where Krupp's father, a mechanical engineer, worked on the Apollo program and then on the Space Shuttle.
In 1961 Krupp attended the Summer Science Program (SSP). Among other things, SSP teaches astronomy to high school students. Krupp has remained active with SSP, first as a graduate student teaching assistant from 1968 to 1972 and later as a frequent guest lecturer. Krupp has said of SSP,
In some respects, SSP remains the most academically cohesive and intense educational experience I have ever had. That, I suspect, is true for most who are fortunate enough to attend it. If it weren't for SSP, my vision would be narrower, my aspirations less ambitious, and my life less rich. I don't exaggerate.
Krupp studied physics and astronomy at Pomona College (the founding member of the Claremont Colleges consortium) in Claremont, California. His undergraduate advisor was Robert J. Chambers. While studying at Pomona College, Krupp participated in cross-country, track, and soccer. He also worked at KSPC, the Pomona College non-commercial community radio station. He lived for two years at the Brackett Observatory, during this time he served as caretaker of the observatory, weatherman, and telescope demonstrator. He received a Bachelor of Arts degree in 1966.
Ed pursued graduate studies in astronomy at the University of California, Los Angeles (UCLA), receiving a Master of Arts degree in 1968 and PhD in 1972. His Ph.D. dissertation concerned the morphology of rich clusters of galaxies. His graduate adviser was George O. Abell.[a]
Concerning his dissertation, it has been said:
- "very respectable" – George Abell (PhD advisor)
- "fine work; a definitive study" – Robert Chambers (undergraduate advisor)
- "a very tedious business" – Edwin Krupp
Krupp began his teaching career as a teaching assistant for the Summer Science Program during his graduate school days. Also, during graduate school he taught at the following education institutions:
He became a planetarium lecturer at Griffith Observatory while also still in graduate school. Ed has been a frequent lecturer throughout his career. He has lectured on science based tours he has led and other venues.
Krupp took his first job at Griffith Observatory in Los Angeles[b] while he was still a doctoral candidate at UCLA. This was as a part-time planetarium lecturer and Krupp did not enjoy this job at first, saying to his wife Robin, "Gee this isn't science, It's showbusiness." But, after he started noticing the audiences responding with increasing enthusiasm he started saying, "Hey, this is showbusiness."
Krupp was appointed Observatory Curator in 1972 upon completion of his PhD. In 1974 the director of Griffith Observatory, William J. Kaufmann III, left, and Krupp was appointed acting director. In 1976 Krupp's title was changed from "acting" director to director.
As early as 1978 Krupp was aware that the observatory would need a future restoration and that there was a need to update equipment and exhibits. So he and Harold and Debra Griffith[c] co-founded the Friends of the Observatory (FOTO). FOTO aids the mission of the observatory in many ways. FOTO partnered with the city to renovate and expand the observatory raising US$30 million for the effort ($26 million in private funds). The observatory closed its doors in 2002 for the $93 Million dollar renovation and expansion. The entire project was spearheaded by Krupp, and the observatory reopened in the fall of 2006.
In 2014 Griffith Observatory had its 80th anniversary and Krupp his 40th as observatory director. At that time, John Ashton of Sunseeker Tours in Long Beach noted, "It’s an L.A. treasure. We get more requests to see this than anything." And, then LA City Councilman Tom LaBonge (whose district included the observatory) observed:
There are many, many, many very special public employees, but there’s only one Dr. Edwin C. Krupp. Not only does he have the greatest building in the city. He’s got the universe.
Krupp has a special interest in the impact of astronomy on ancient belief systems, and is an internationally recognized expert on traditional astronomies. He is noted for his many contributions to the field on which he has written extensively, and he has visited, and studied, nearly 2,000 prehistoric, and historic sites around the world.
Krupp has traveled around the world for his archaeoastronomy studies. These trips have also taken him to sites close to home such as the Burro Flats pictograph site in the Simi Hills of Southern California, which he first visited in 1979. Over the years, Krupp has made semi-regular trips to that site to conduct solstice observations.
Krupp has shared his studies of archaeoastronomy with the general public by including archaeoastronomy topics in Griffith Observatory planetarium programs, writing books and magazine articles, appearing in documentary films, and leading tours to archaeological sites that are associated with ancient astronomy.
Krupp has written several books for adults and for children. His first two adult books (one being his doctoral dissertation), both derive from the work he did on rich clusters of galaxies while a PhD student at UCLA. His remaining adult books derive from his interests in archaeoastronomy, and contain extensive original research and analysis, while also being educational in nature. They cover astronomy in ancient cultures and the effect of beliefs about the sky on those cultures.
