This book concerns the history of the Yerkes Laboratories of Primate Biology as they existed in Orange Park, Florida, during 1930-1965. The Yerkes Laboratories were among the more important facilities in the history of comparative psychology and related fields. They held the largest collection of chimpanzees for research in the world. Many important scientists spent parts of their careers there. A primary theme of the book concerns changing patterns of patronage for science as it shifted from private foundations to federal agencies and the effects this had on the scientific enterprise.
