Gerard DebreuGerard Debreu (July 4, 1921–December 31, 2004) was a French-born American economist who won the 1983 Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel. He was born in Calais. Just prior to the start of World War II he finished college, but instead of preparing for the university he studied at an improvised math curriculum in Ambert. Later on he moved to Grenoble. In 1941 he was admitted to the cole Normale Suprieure, which he was about to graduate from in 1944 when the D-Day made him enlist in the Allies army. He was transferred for training to Algeria and then served in French occupational forces in Germany until July 1945. Eventually he graduated in the end of 1945 and later became interested in economics, particularly the general equilibrium theory of Leon Walras. He was an assistant in the Centre National de la Recherche Scientifique and then obtained the Rockefeller Fellowship which allowed him to visit several American universities, as well as those in Uppsala and Oslo in 1949-50. After an offer has been made to him by the University of Chicago for a position as a Research Associate, Debreu started working there in summer 1950. There he remained for five years, returning to Paris periodically. In 1954 he published a breakthrough paper titled Existence of an Equilibrium for a Competitive Economy (together with Kenneth Arrow). In 1955 he moved to Yale University. In 1959 he published his first monograph, Theory of Value. In 1960-61 he worked at Stanford University and since 1962 at the University of California, Berkeley where he held the title University Professor and Class of 1958 Professor of Economics and Mathematics Emeritus. During his leaves in late sixties and seventies he visited universities in Leiden, Cambridge, Bonn, and Paris. His later studies centered mainly on the theory of differentiable utility functions and least concave utility functions. He was awarded the 1983 Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel for his work on general equilibrium economics. In 1976 he received the French Legion of Honor. Debreu married Franoise Bled in 1946 and had two daughters, Chantal and Florence, born in 1946 and 1950 respectively. Debreu died in Paris at the end of 2004 of natural causes.
