["Conquer public opinion!:" Latin American eugenics as seen in the magazine Viva Cien Años, Argentina, 1934-1947].

Eugenics arrived in Argentina as a discipline at the beginning of the twentieth century. It was widely embraced by intellectuals and healthcare professionals, in the midst of a series of actions undertaken to strengthen networks within the academic and political worlds. One of those initiatives was the magazine Viva Cien Años, founded in 1934 as a popular science publication. This article presents the possibilities of the body of documentation relating to the magazine, which was published in Argentina until 1947. The central thesis argues that the appearance of this publication shows the impact of eugenics in the 1930s in Argentina, and its strategies for conquering public opinion.
