in mathematics, engineering, and economics. An important contribution of Le Corbeiller's was to connect the mathematical theory of self-oscillators with the thermodynamics of engines. At Harvard, Le Corbeiller had a major influence on the work of economic theorist Richard M. Goodwin, who used concepts from nonlinear systems to describe the business cycle in macroeconomics. Le Corbeiller also cultivated an interest in the history and philosophy of science, which he combined with his enthusiasm for general and adult education. He was actively involved in the initiative of Harvard President James Bryant Conant to develop a history of science–based general science education, collaborating in that effort with other lecturers such as Edwin C. Kemble, Gerald Holton, I. Bernard Cohen, and Thomas Kuhn. Personal life Philippe Le Corbeiller married Dorothy Leeming, a citizen of the United States, in Paris in 1924. They had one son, Jean, who graduated from Harvard in 1948, and who worked as editor of Scientific American magazine and as professor at the Seminar and Lang Colleges of the New School for Social Research, in New York City. In 1952, Philippe Le Corbeiller's mother donated to Harvard's Fogg Museum a bouillon cup and a saucer reportedly used by Marie Antoinette during her imprisonment and passed down through Madame Campan. After retiring from Harvard in 1960 Philippe Le Corbeiller taught briefly at the New School and at Smith College. Widowed in 1962, he married Pietronetta Posthuma, the widow of Balthasar van der Pol, in 1964 in New York City. The couple settled in the Netherlands in 1968. Le Corbeiller died in Wassenaar in 1980.
