This paper aims to study the circulation of ideas and actors generated through the Latin American Center for Human Economy (CLAEH) in Montevideo, capital of Uruguay, which articulated the network of the French movement Economy and Humanism in Latin America. It covers the period from 1957, when the center was created, to 1966, when the Dominican priest Louis-Joseph Lebret, founder of Économie et Humanisme and main promoter of CLAEH, died.
