Milton Winternitz led the Yale Medical School as its dean from 1920 to 1935. Dedicated to the new scientific medicine established in Germany, he was equally fervent about "<answer>social medicine</answer>" and the study of humans in their culture and environment. He established the "Yale System" of teaching, with few lectures and fewer exams, and strengthened the full-time faculty system; he also created the graduate-level Yale School of Nursing and the Psychiatry Department, and built numerous new buildings. Progress toward his plans for an Institute of Human Relations, envisioned as a refuge where social scientists would collaborate with biological scientists in a holistic study of humankind, unfortunately lasted for only a few years before the opposition of resentful anti-Semitic colleagues drove him to resign.
