Celebrating 60 years of preserving and sharing history

In 1965, the Archives of the History of American Psychology (AHAP) received its first official collection, consisting of just two boxes of papers from psychologists Harry and Leta Stetter Hollingworth. In the 60 years since, the Archives have grown from those two boxes to nearly 6,500 feet of multimedia archival collections. Through these materials, the Archives preserves and shares the stories of psychology and the diverse communities of researchers, scholars, educators, and practitioners whose groundbreaking work helps us better understand ourselves, our world, and each other. Join us as we reflect on our 60th Anniversary and plan for a secure and vibrant future.

Explore an expanded timeline of AHAP's history.
