Born in Hemer, Westphalia, he studied art history and philosophy at the University of Vienna, receiving his doctorate in 1908. He then went to England to receive voice training, as he planned to become a professional singer. He later received training in medicine and psychiatry, serving as an Army surgeon during World War I.
In 1919 he became assistant to Karl Wilmanns at the psychiatric hospital of the University of Heidelberg. His task was to expand an earlier collection of art created by the mentally ill and started by Emil Kraepelin. When he left in 1921 the collection was extended to more than 5000 works by about 450 "cases".
In 1922 he published his first and most influential book "Bildnerei der Geisteskranken. Ein Beitrag zur Psychologie und Psychopatologie der Gestaltung" (The plastic activity of the mentally ill. A contribution to the psychology and psychopathology of formal configuration), richly illustrated with examples from the collection. While his colleagues were reserved in their reaction, the art scene was enthusiastic. Jean Dubuffet was highly inspired by the works, and the term Art Brut was coined.
The book is mainly concerned with the borderline between psychiatry and art, illness and self-expression. It represents one of the first attempts to analyse the work of the mentally ill.
After short stays at sanatoriums in Zurich, Dresden and Wiesbaden, he began a psychotherapy practice in Frankfurt in 1925, but without much success. He continued to write books, and a half dozen were published in his lifetime. His hopes to find a permanent position at a university were never fulfilled. Disillusioned by professional failures, and after three failed marriages, he moved in with an aunt in Munich and retreated from public life, making a living from giving lectures and writing essays. He died in 1933 in Munich of typhus.
Shortly after his death the Prinzhorn Collection was stowed away in the attics of the university. In 1938 a few items were displayed in the Nazi propaganda exhibition Entartete Kunst ("Degenerate Art"). Since 2001 the collection has been on display in a former oratory of the University of Heidelberg.
