Ecologia, cooperação internacional e configuração biogeográfica do Brasil: Pierre Dansereau e o acordo científico Brasil-Canadá nos anos 1940

The article analyzes work done in Brazil by Canadian ecologist Pierre Dansereau (1911-2011) under a scientific cooperation agreement between the Intellectual Cooperation Division of the Brazilian Ministry of Foreign Affairs and the Canadian Embassy, signed in 1944. Dansereau, a leading figure in twentieth-century ecology, came to Brazil in 1945 as director of the Quebec Province Biogeography Service. His proposed ecological research plan called for the organization of scientific expeditions, specialized staff training, and future international cooperation with such Brazilian institutions as the National Museum, the National Geography Council, and the Oswaldo Cruz Institute. His stay in Brazil affords an opportunity to analyze the interrelations between the geopolitics of Brazilian developmentalism, Quebec nationalism, Pan-Americanism as an intellectual movement, and the attempt to establish a francophone research network in biogeography, ecology, and plant sociology

A trajetória de Henrique da Rocha Lima e as relações teuto-brasileiras (1901-1956) The career of Henrique da Rocha Lima and German-Brazilian relations (1901-1956)

A trajetória de Henrique da Rocha Lima vincula-se estreitamente às relações científicas e culturais entre Brasil e Alemanha. Seus trabalhos científicos foram produzidos em instituições de pesquisa biomédica dos dois países, mas foi na Alemanha que ele conquistou projeção internacional, graças a suas pesquisas nos campos da microbiologia, patologia e medicina tropical. Lastreado pelo prestígio e boa inserção nas comunidades científicas brasileira e alemã, contribuiu para o estreitamento do intercâmbio intelectual entre os dois países, mobilizando diversos personagens e instituições como pontos de apoio. Apresentam-se percalços e desafios impostos pelo estudo desse personagem complexo, cuja trajetória lança luz, a um só tempo, sobre os meandros das relações científicas internacionais e sobre processos sócio-históricos marcantes na institucionalização das ciências no Brasil.<br>The career of Henrique da Rocha Lima is closely linked to cultural and scientific relations between Brazil and Germany. He pursued his scientific work at biomedical research institutions in both countries, but it was in Germany that he attained international standing, thanks to his research in the fields of microbiology, pathology and tropical medicine. His prestige and active participation in both Brazil's and Germany's scientific communities meant he was able to further academic interchange between both nations, mobilizing many people and institutions to contribute to this process. I present the obstacles and challenges faced in studying this complex character, whose career sheds light on the machinations of international scientific relations and some socio-historical processes that marked the institutionalization of science in Brazil
