This report, which is part of an ongoing PhD investigation, presents a general panorama of the history of the Fellowship Program in Agricultural Sciences that the Rockefeller Foundation (RF) offered in Mexico from 1940 to 1970. For this purpose, the main subject of analysis is the group of Mexicans – or residents of Mexico – who carried out postgraduate studies, training or research trips abroad, mainly to the United States of America. Furthermore, analysis is also carried out regarding Latin American students who completed courses in Mexico within the Rockefeller program. This initial, and by no means exhaustive, analysis of the subject aims to show the link between the Fellowship Program and the intellectual revolution in agriculture. There was an academic and scientific exchange of ideas, promoted by the RF's philanthropic work, linked with agronomic professionalization and the Green Revolution. These considerations are the basis that will later allow my PhD-level research to center on the itineraries of the fellows. These factors will also provide the foundation for my analysis of the ways in which their aspirations influenced the program, through their adherence, criticism and/or appropriation of the guidelines for the RF's philanthropic work in science and of the agrarian goals of the Mexican government.
