It can fairly be said that modern psychiatric diagnosis was "born" in a 1970 paper on schizophrenia.
The authors, Washington University psychiatry professors Eli Robins and Samuel B. Guze, rejected the murky psychoanalytic diagnostic formulations of their time. Instead, they embraced a medical model inspired by the careful 19th-century observational work of Emil Kraepelin, long overlooked during the mid-20th-century dominance of Freudian theory. Mental disorders were now to be seen as distinct categories, much as different bacterial and viral infections produce characteristic diseases that can be seen as distinct "natural kinds."
