This paper aims to analyze the organization and the early years of the first scientific association devoted to anthropological sciences in Argentina. Formed in 1936 by a heterogeneous group of people with varied interests, the Argentine Society of Anthropology was a space for sociability as well as exchange and dissemination of knowledge and practices linked to different disciplines of human sciences. It also attempted to strengthen the image of these study areas as scientific disciplines. The analysis of the Argentine Society of Anthropology shows the role of a private organization in the strengthening of anthropological sciences in Argentina during the 1930s and 1940s. Furthermore, it shows how the anthropological sciences back then could expand thanks to a heterogeneous network of relationships scattered over different provinces and national territories. This development was also made possible by the active participation in both the society and the anthropological sciences of enthusiasts and students, many of whom were women.
