The Center for the History of Psychology was founded as the Archives of the History of American Psychology (AHAP) on October 11, 1965 by psychologists Dr. John A. Popplestone and Dr. Marion White McPherson.
Over the years, AHAP grew, providing educational programming and tours for school groups, initiating a monograph series, and supporting travelling exhibits.
In 2010, the Archives became the Center for the History of Psychology to reflect this increased scope of activities and offerings. Today, the Center includes the Archives of the History of American Psychology as well as a Museum of Psychology and continues a 45-year tradition of caring for the historical record of psychology.
