Historians and other scholars have recognized the centrality of visuality and images to the modernization theory that drove US policy in the Global South during the Cold War. However, these scholars have so far failed to take into account the process of creating and consuming images and how that process shaped popular and expert ideas of what modernization would look like. Focusing primarily on efforts in Latin America, my book will trace the complex interplay between documentary filmmaking and international development institutions and agencies formed during and in the decades after World War II. This report traces the convergence of economic development and documentary film by examining some of the 1940s productions of Nelson Rockefeller's Office of the Coordinator of Inter-American Affairs (OCIAA), as well as some Rockefeller Foundation agricultural films of the early 1960s. In particular, it looks at a few films made by director Willard Van Dyke, who was trained in the New Deal documentary tradition and went on to make films for both the OCIAA and the Rockefeller Foundation.
