Eugen Bleuler

Paul Eugen Bleuler (; German: [ˈɔɪɡeːn ˈblɔɪlər]; 30 April 1857 – 15 July 1939) was a Swiss psychiatrist and eugenicist most notable for his contributions to the understanding of mental illness. He coined many psychiatric terms, such as "schizophrenia", "schizoid", "autism", depth psychology and what Sigmund Freud called "Bleuler's happily chosen term ambivalence".
