 in Leipzig, and was appointed professor of psychiatry at the Univ. of Dorpat, Heidelberg (1891) and Münich (1903), where he also directed a clinic. Kraepelin authored nine editions of a textbook which classified mental diseases according to their cause, symptomatology, course, final stage, and pathological anatomical findings, producing a system of classification which has relevance even today. He established the clinical pictures of dementia praecox (now known as schizophreniaschizophrenia

) in 1899, after analyzing thousands of case histories. Kraepelin was concerned only with diagnostic classification, and did not accept the theory of unconscious mental activity postulated by psychoanalysts. His classification of mental disorders served as the foundation for the Diagnostic and Statistical Manual (DSM) and the International Classification of Diseases (ICD), the standard reference text used by psychiatrists today. His major work is his Textbook of Psychiatry (9th ed. 1927).

Kraepelin, Emil


Born Feb. 15, 1856, in Neustrelitz, Mecklenburg; died Oct. 7, 1926, in Munich. German psychiatrist. Professor of psychiatry at the universities of Dorpat (now Tartu; from 1886), Heidelberg (from 1891), and Munich (from 1903).

In 1922, Kraepelin left his professorship, to work at the Munich Research Institute for Psychiatry, which he had founded in 1917. His principal works were devoted to elaborating the clinical practice of mental diseases and their classification, which was constructed by Kraepelin according to the nosological principle. He believed that single causes entailed single consequences, that is, symptoms; Kraepelin attributed great significance to their course and outcome in delimiting nosological forms. One of Kraepelin’s major achievements was the division of endogenic psychoses according to their outcome into two categories: dementia praecox (schizophrenia) and manic-depressive psychosis.

His idealistic approach to the causes of mental disease led Kraepelin to assign too much significance to heredity and constitutional factors; he understood cause and effect as something permanent and immutable and did not take into account such factors as the body’s reactive features and the effect of the environment. Nevertheless, Kraepelin’s nosology remains the basis of clinical psychiatry. He created an important psychiatric school. Kraepelin’s Textbook of Psychiatry, upon which many generations of psychiatrists were reared, went through eight editions (from 1883).

While this profile is not itself new--it has been described at least since the time of Kraepelin, and was described by Andreasen (51) as a result of a "burning out" disease process that leaves an "empty shell" in place of what a person used to be--it is a profile that is of increasing concern to hospital staff and administrators.
