a teaching assistant for the Summer Science Program during his graduate school days. Also, during graduate school he taught at the following education institutions: El Camino College University of Southern California University of California, Los Angeles He became a planetarium lecturer at Griffith Observatory while also still in graduate school. Krupp has been a frequent lecturer throughout his career. He has lectured on science based tours he has led and other venues. Griffith Observatory Krupp took his first job at Griffith Observatory in Los Angeles 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 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. Krupp often appears in the media to discuss and explain developments and recent discoveries in astronomy, as well as discuss current celestial events. 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: Archaeoastronomy 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
