Adolf Meyer

Adolf Meyer (1866–1950) was a Swiss-born psychiatrist who served as the first psychiatrist-in-chief of Johns Hopkins Hospital from 1910 to 1941 and directed the Henry Phipps Psychiatric Clinic. He is best known for developing the concept of psychobiology, which integrated biological, social, and psychological factors in understanding and treating mental illness, and for his emphasis on detailed patient case histories. He is widely regarded as the most influential figure in American psychiatry during the first half of the twentieth century.
