Paul Eugen Bleuler and the Birth of Schizophrenia (1908)
The term “schizophrenia” was coined 100 years ago, on April
24, 1908, when Paul Eugen Bleuler gave a lecture at a meeting of
the German Psychiatric Association in Berlin (1): “For the sake of
further discussion I wish to emphasize that in Kraepelin’s demen-
tia praecox it is neither a question of an essential dementia nor of
a necessary precociousness. For this reason, and because from
the expression dementia praecox one cannot form further adjec-
tives nor substantives, I am taking the liberty of employing the
word schizophrenia for revising the Kraepelinian concept. In my
opinion the breaking up or splitting of psychic functioning is an
excellent symptom of the whole group” (2).
Kraepelin’s use of “dementia” derived from the Latin word mens
and the prefix de-, expressing privation; it was a noun that implied a
static condition. While Kraepelin selected descriptions of the symp-
toms and studied their time course mostly from patients’ records,
Bleuler collected material directly from his p assionate clinical work.
By accommodating himself to the spatial and temporal environ-
ment of his patients, he realized that the condition was not a single
disease (he referred to a “whole group” of schizophrenias ), was
not invariably incurable, and did not always progress to full demen-
tia, nor did it always and only occur in young people. The main
symptoms of this disease were the loosening of associations, distur-
bances of affectivity, ambivalence, and autism (“the four A’s”) (4).
However, the splitting of different psychological functions, resulting
in a loss of unity of the personality, was the most important sign of
disease in Bleuler’s conception (4). Thus, he challenged the ac-
cepted wisdom of the time and advanced his purportedly less static
and stigmatizing concept by juxtaposing the Greek roots schizen
(σχι´ζειν, “to split”) and phre¯n, phr en- (ϕρη´ν, ϕρεν-, orig inally de-
noting “diaphragm” but later changing, by metonymy, to “soul,
After completing his studies in medicine (1881) and mental
and nervous diseases (1883), Bleuler visited Paris, London, and
Munich. He became director of a small psychiatric clinic situated
in an abandoned monastery on the Rhine (Rheinau, 1886–1898),
then he was appointed professor and director of the Burghölzli
Asylum in Zurich (1898–1927). Among his pupils there were such
outstanding personalities as Carl Gustav Jung, Karl Abraham, Eu-
gene Minkowski, Ludwig Biswanger, and Hermann Rorschach.
He published the work “Dementia praecox oder Gruppe der
Schizophrenien” in 1911 (3) and the book Lehrbuch der Psychiat-
rie in 1916 (5). He died in 1939 in Zollikon, Switzerland, where he
had been born in 1857.
