On May 9, 1993, Earl Droessler interviewed Bernard Vonnegut for the American Meteorological Society's oral history project in Schenectady, New York. The interview focuses on Vonnegut's career in atmospheric sciences, beginning with his education in physical chemistry at MIT and transition into meteorology through collaborations with colleagues like Wallace Howell and Henry Houghton. Vonnegut describes his work during World War II in the Chemical Warfare Service, which included studies on aerosols and de-icing aircraft, leading to his association with influential figures like Irving Langmuir and Vincent Schaefer. Vonnegut recounts his groundbreaking contributions to cloud physics, including the development of silver iodide as a cloud-seeding agent. He highlights his tenure at General Electric, where he was part of the team conducting pioneering research on nucleation and cloud modification. The conversation also covers his later transition to Arthur D. Little, where he explored atmospheric electricity and proposed innovative methods for dissipating warm fog. Throughout the interview, Vonnegut reflects on the freedom and opportunities he had in his career to pursue independent research, emphasizing the collaborative environment at institutions like MIT and GE. The interview provides insights into key developments in atmospheric science, the impact of wartime research on meteorological advancements, and the interdisciplinary nature of Vonnegut's work. It also captures his interactions with notable contemporaries and the broader implications of his research on weather modification and understanding of atmospheric processes.
