Rachael Rosner, PhD is a Boston-based independent scholar. She earned a B.A. in Ancient Greek from the University of Michigan, an M.A in History from the University of Rochester, and a Ph.D. in psychology from York University, Canada. She also completed a 3-year National Science Foundation Post-Doctoral Fellowship in the Department of the History of Science at Harvard University. Her general interest is in the history of 20th century American psychotherapy, with a specific focus on the origins of Aaron T. Beck’s Cognitive Therapy. Her historical articles about Beck have appeared in the journals History of Psychology, Isis, and Cognitive Psychotherapy. She is also the recipient of the Early Career Award and the Best Article Award from Division 26 (History of Psychology) of the American Psychological Association. Dr. Rosner is currently writing the first comprehensive biography of Beck, tentatively titled In Beck’s Basement: Aaron T. Beck and the Emergence of Cognitive Therapy. Her project is a study of the conceptual and clinical bridges between Beck’s cognitive therapy and the particular strain of ego psychology that David Rapaport, Erik Erikson and others innovated at Riggs in the 1950s, and in which Beck trained from 1950 to 1952. She also is exploring the evolution of the ego psychology model at Riggs, both through a study of archival documents at the Riggs library and through participation in case conferences.
