Adolf Meyer (1866–1950) was an early supporter of occupational therapy as a connection between an individual’s activities and mental health. Meyer, a psychiatrist, incorporated community-based activities and services to develop skills of everyday life into treatment with his patients. He developed an approach he called “psychobiology” and based treatment on the combined life experience and physiological and biological data of patients. He recommended taking detailed life histories of patients, revolutionizing case records. Meyer viewed individuals holistically as organisms that interact with and adapt to their environment. Meyer hired Eleanor Clarke Slagle as Director of Occupational Therapy at Johns Hopkins Hospital and served as a major influence on her work.
