On August 4, 1987, Earl Droessler interviewed Eugene Bollay for the American Meteorological Society Oral History Project. Bollay, born in Stuttgart, Germany, in 1912, immigrated to the United States with his family in 1924. He pursued electrical engineering at Northwestern University, but job scarcity led him to accept a Guggenheim assistantship in meteorology at Caltech in 1935. This decision sparked his lifelong career in meteorology. In the interview, Bollay reflects on his early involvement in aviation meteorology with American Airlines and his academic work at Caltech under Irving Krick. He discusses his contributions to the Los Angeles County Flood Control District, where he developed methods to predict rainfall intensity for flood management. Bollay also highlights his work with the U.S. Weather Bureau and his service during World War II, teaching meteorology at the Naval Academy and supporting Allied bombing operations in Europe. Post-war, Bollay was involved in the early development of meteorological research through the Office of Naval Research (ONR), collaborating with notable figures such as Rossby and von Neumann. He emphasizes the role of ONR in advancing dynamic meteorology and the development of numerical weather forecasting. Bollay later transitioned to applied meteorology, co-founding North American Weather Consultants, where he pioneered cloud seeding programs aimed at enhancing precipitation for hydroelectric power. The interview concludes with Bollay discussing his leadership roles in the American Meteorological Society (AMS), his tenure as AMS president, and his efforts to promote operational meteorology and applied research, particularly in weather modification.
