Ernst Kretschmer was born in 1888 in Wüstenrot, Germany, and spent his professional life as a psychiatrist, neurologist, and university teacher. His career spanned significant academic appointments at the universities of Tübingen and Marburg, where he developed influential, if controversial, theories concerning the relationship between human physical constitution and psychiatric conditions during the early 20th century.
Early Education and Clinical Training
Kretschmer attended the Johannes-Kepler-Gymnasium before enrolling at the University of Tübingen, where he studied medicine, theology, and philosophy from 1906 to 1912. He began his professional clinical training in 1913 as an assistant to Robert Gaupp in Tübingen. By 1918, he completed his habilitation and continued serving as an assistant medical director in the region until 1926.

Take the IQ test →Constitutional Typology
Kretschmer is primarily known for developing a classification system that categorized humans into four main physical types: asthenic, athletic, pyknic, and dysplastic. He proposed that these physical forms correlated with specific temperaments and predispositions toward mental disorders. Specifically, he linked the pyknic physique to manic-depressive illness, while associating asthenic and athletic types with schizophrenia. Although these associations are no longer considered valid in modern personality psychology, they represented an early attempt to establish a constitutional framework for psychiatric diagnostics.
Medical Research and Clinical Contributions
Beyond physical typology, Kretschmer conducted significant research into sensitive paranoia and chronic vegetative states. He was the first to describe the persistent vegetative state, a condition now sometimes referred to as Kretschmer's syndrome. Between 1915 and 1921, he refined the differential diagnosis between schizophrenia and manic-depressive psychosis. During his career, he served as the director of the psychiatric clinic at the University of Marburg starting in 1926 and later returned to direct the psychiatric clinic at the University of Tübingen from 1946 until 1959.
Professional Organizations and Later Life
Kretschmer was a founding member of the International General Medical Society for Psychotherapy in 1927, serving as its president beginning in 1929. He resigned from the organization in 1933 for political reasons. Following this period, he signed the pledge of allegiance to Adolf Hitler by German university professors. In his later years, he received the Golden Kraepelin Medal in 1956 and the Commander's Cross of the Order of Merit of the Federal Republic of Germany in 1958. He was also an Honorary Fellow of the British Psychological Society and a member of both the German Academy of Sciences at Berlin and the Leopoldina. He died in 1964 in Tübingen.
