- Emil Kraepelin (1856_1926) : Emil Kraepelin published a list of categories of mental illness in 1883. Until recent times, many clinicians used this list to diagnose mental illness. Today the Diagnostic and Statistical Manual of Mental Disorders (2000) serves the same purpose. Kraepelin was also a pioneer in the field known today as Psychopharmacology.
