born Nov. 8, 1884, Zürich, Switz.

Swiss psychiatrist.
The eldest son of an art teacher, he was given the nickname Kleck, meaning "inkblot," as a schoolboy because of his interest in sketching. After receiving his M.D. from the University of Zürich in 1912, he became a practitioner of psychoanalysis and became vice president of the Swiss Psychoanalytic Society in 1919. He devised the Rorschach test to gauge the perceptions, intelligence, and emotional traits of his patients and used it to gather the data that he summarized in Psychodiagnostics (1921).
