Samuel Calmin Kohs (New York June 2, 1890 – San Francisco January 23, 1984) was an American psychologist who spent his career in clinical and educational psychology. He was awarded a B.A. degree at City College of New York, an M.A. at Clark University. He developed for his doctoral dissertation in 1919 at Stanford University a set of small variously colored blocks (known as the Kohs blocks) that are used to form test patterns in psychodiagnostic examination.
