Robert D. Dripps, M.D. (1911 to 1973), helped found academic anesthesiology. Newly reviewed teaching slides from the University of Pennsylvania (Philadelphia, Pennsylvania) contain six anesthesia records from 1965 to 1967 that involved Dripps. They illustrate the clinical philosophy he taught—to consider administration of each anesthetic a research study. Intense public criticism in 1967 for improper experimentation on patients during anesthesia changed his clinical and research philosophies and teaching.
