Robert Mearns Yerkes (1876 - 1956) worked in the field of comparative psychology and developed the Army Alpha intelligence test, given to over 1 million United States soldiers in World War I. He founded the Yale University Laboratories of Primate Biology, which were renamed the Yerkes Regional Primate Research Center and moved to Emory University in Atlanta, Georgia. The primate language, Yerkish, was developed there.
