Paul Eugen Bleuler was a Swiss psychiatrist and humanist most notable for his contributions to the understanding of mental illness. He coined several psychiatric terms including "schizophrenia", "schizoid", "autism", depth psychology and what Sigmund Freud called "Bleuler's happily chosen term ambivalence".

Burghölzli, named after the wooded hill in the district of Riesbach in southeastern Zürich where it is located, is the Psychiatrische Universitätsklinik Zürich, a psychiatric hospital in Switzerland. As a research hospital, it is associated with the University of Zürich.
