"Our Primate Materials" Robert M. Yerkes and the Introduction of the Primate to Problems of Human Betterment in the American Eugenics Movement

Caitlin Garcia-Feehan, Purdue University

Abstract

My master's thesis examines how eugenicist and psychologist Robert M. Yerkes’ experimental intelligence research helped to situate the non-human primate as the ideal research subject for human betterment research in the twentieth century U.S. Yerkes believed that the primate was the ideal research subject to address questions of human betterment and social welfare, specifically best to create methods of evaluating the imagined threat of intellectual disability. While Yerkes has been studied extensively in the history of psychology, primatology, and eugenics, rarely have his separate contributions to these fields been placed in conversation with one another. Placing the primate at the center of Yerkes’ work allows for all three fields to engage with one another in a new perspective. By analyzing Yerkes’ publications about the Multiple-Choice Experiment within the context of the American eugenics’ movement, we can see how the primate came to hold a central position in U.S. scientific research, the advancement of human welfare and betterment, and as a means of defining what it means to be human. This story offers a glimpse into this longer process of how the primate came to occupy this position, but even a glimpse offers historians of the American eugenics’ movement new questions. What was the role of the non-human animal in the formulation of American eugenic theories? How have we historically used the natural world in our attempts to separate ourselves from it? And can we truly reconcile a history with eugenics if we continue to ignore the role of animals within it, they who today exist unquestionably within the status of the sub-human?
