Abstract

Histories of economic development during the Cold War do not typically consider connections to race science and eugenics. By contrast, this article historicizes the debates sparked by the International Labor Organization’s Puno–Tambopata project in Peru and demonstrates how Cold War development practice shared common epistemological terrain with racial and eugenic thought from the Andes. The International Labor Organization project’s goal of resettling indigenous groups from the Peruvian highlands to lower-lying tropical climates sparked heated debates about the biological specificity of Andean highlanders’ physiques and ability to survive in the tropics. Such concerns betrayed the antitypological consensus expressed in the United Nations Educational, Scientific and Cultural Organization Race Statements and defended by one of the main proponents of the resettlement project, the Swiss–American anthropologist Alfred Métraux. The concern with Andean racial types was central to the research agenda of the acclaimed Peruvian physiologist Carlos Monge, who endorsed modernization projects that did not entail moving highlanders outside of their traditional climate. The debates sparked by the Puno–Tambopata project demonstrate how Cold War development discourse grappled with racial and eugenic thought from Latin America and the Global South and thereby produced projects of indigenous “improvement.”
