In The Celluloid Specimen, Benjamín Schultz‑Figueroa examines rarely seen behaviorist films of animal experiments from the 1930s and 1940s. These laboratory recordings-including Robert Yerkes's work with North American primate colonies, Yale University's rat‑based simulations of human society, and B. F. Skinner's promotions for pigeon‑guided missiles-have long been considered passive records of scientific research. In Schultz‑Figueroa's incisive analysis, however, they are revealed to be rich historical, political, and aesthetic texts that played a crucial role in American scientific and cultural history-and remain foundational to contemporary conceptions of species, race, identity, and society.
