Amid rapid social changes in Brazil in the 1950s, wide-reaching collective research projects in the social sciences were conducted in partnership between Brazilian and international agencies working in regional development. Cooperation between social scientists and government staff was based on the expectation that social and anthropological studies would orient the changes then under way. By approaching the research program in the São Francisco River Valley, the article examines a turning point in the career of sociologist Donald Pierson, combining analyses of context and content in his intellectual production. Pierson concentrated initially on the institutionalization of the social sciences in Brazil, promoting a standard of sociological work based on scientific research. In his research in the São Francisco River Valley, Pierson adopted a new approach by combining the sociologist’s role as scientist with that of agent of social change, thereby highlighting the importance of the application of sociological knowledge in practice.

Dans les années 1950 au Brésil, au milieu de changements sociaux accélérés, on a entrepris d’importants projets collectifs de recherche en sciences sociales en partenariat avec des agences nationales et internationales intéressées par le développement régional. La coopération entre chercheurs et techniciens de la fonction publique était fondée sur le souhait que les études sociologiques et anthropologiques pourraient guider les transformations en cours. À partir de l’examen du programme de recherches de la Vallée du Rio São Francisco, on cherche, dans cet article, à saisir les inflexions de trajectoire du sociologue Donald Pierson, en y associant l'analyse du contexte et celle du contenu de sa production intellectuelle. Au départ, Pierson s’est concentré sur l’institutionnalisation des sciences sociales au Brésil, en proposant un modèle de travail sociologique calqué sur la recherche empirique. Mais, au cours de ses enquêtes dans la vallée du fleuve, il adopte une nouvelle perspective en incorporant au rôle de spécialiste sociologue celui d'agent du changement social, tout en soulignant l’importance de l'application du savoir sociologique.

O objetivo deste artigo é fazer um balanço da literatura sobre os Estudos de Comunidade (EC) no Brasil, destacando o contexto intelectual em que foram produzidos e os debates que suscitaram, especialmente entre as décadas de 1940 e 1960. Método de pesquisa em comunidades, oriundo da Antropologia, em investigações sobre o processo de mudança social, os EC estiveram em voga nos Estados Unidos entre os anos 1920 e 1950, tendo papel fundamental na institucionalização das Ciências Sociais no Brasil. Destacamos três aspectos na produção desses estudos no país, iniciando com uma abordagem conceitual: definições, origem e sua relação com temáticas marcantes nos anos 1950. Em seguida, privilegiamos os aspectos relacionados ao papel dos EC na história das Ciências Sociais no Brasil, com destaque para o processo de institucionalização das Ciências Sociais. Por fim, revisitamos os debates que tais estudos geraram entre os cientistas sociais quanto ao padrão de trabalho sociológico a ser desenvolvido naquele momento.

The purpose of this article is to examine the literature about Community Studies(CS) in Brazil, highlighting their intellectual context of production and the debates evoked by them, especially between the 1940's and 1960's. As a research method arising from Anthropology on communities in social change process, CS was used in United States between 1920's and 1950's, and played a fundamental role in the institutionalization of Social Sciences in Brazil. Three aspects are highlighted on CS production: first, in a conceptual approach, we discuss their definitions, origins and relation to main topics in the 1950's. The second aspect is related to the role of CS in the history of Social Sciences, especially their institutionalization process. By the end, we revisit the debates between social scientists about the sociological work standard to be developed at that time.
