Eugen Bleuler, Swiss psychiatrist and eugenicist (died 1940)

Paul Eugen Bleuler was a Swiss psychiatrist and eugenicist most notable for his influence on modern concepts 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". Bleuler remains a controversial figure in psychiatric history for his racist, sanist, and ableist beliefs, as well as his implementation of eugenic practises in psychiatry based on these beliefs, most notably at the Burghölzli clinic in Zurich.
