Eugenics in Latin America

Abstract

Abstract Eugenics emerged in Latin America in the early 20th century on the intellectual foundations of 19th-century social Darwinism and positivism, and expanded in contexts influenced by Catholicism, nationalism, and transnational scientific exchange. Although the extent and objectives of eugenic policies, practices, and organizations varied across the region, Latin American eugenicists tended to subscribe to neo-Lamarckian principles of environmental modification, foreground puericulture or infant and maternal care, and support new techniques of human measurement associated with biotypology. Overall, eugenics in Latin America was less extreme than in Anglo and Nordic countries, rarely resulting in sanctioned policies of compulsory sterilization or euthanasia. It was an integral component of programs designed to combat infectious ailments, especially sexually transmitted diseases, and to ameliorate national health indicators. This overlap meant that eugenics sometimes was less visible as a stand-alone movement, and that its tenets were absorbed with little friction into public health and social welfare infrastructures and campaigns. At the same time, eugenic racism was expressed in calls for immigration restriction that reverberated across Latin America, most notably in the 1910s and 1920s. In retrospect, eugenics in Latin America contributed both to exclusionary policies that stigmatized certain social groups and to overarching campaigns for health and wellness that were backed by a diverse political spectrum that could include feminists, Socialists, and military leaders.
