GERARD DEBREU (1921-2004)
Prêmio Nobel 1983
Economista francês, obteve o Prêmio Nobel de Economia em 1983 por ter incorporado novos métodos analíticos à teoria econômica e por sua rigorosa reformulação da teoria do equilíbrio geral.
Nascido em Calais, França, em 4 de Julho de 1921, Debreu, que adquiriu a nacionalidade norte americana em 1975, interrompeu seus estudos de Matemática para entrar no Exército francês após a invasão da Normandía pelos Aliados em 1944, e só os finalizou após o conflito.
Influenciado pela obra de Léon Walras, Debreu concentrou suas pesquisas em economia. Em 1950 foi para os Estados Unidos em 1950 com uma bolsa Rockefeller e até 1960 trabalhou na Cowles Comission for Research in Economics na Universidade de Chicago. Em 1961 pesquisou no Center for Advanced Study in the Beahavoiral Sciences em Stanford, foi professor associado na Universidade de Yale e em 1962 passou à Universidade de Berkeley até sua aposentadoria no ano de 1991.
Faleceu em 31 de dezembro de 2004.
