The French physiologist Claude Bernard (1813–1878) is credited with originating the experimental approach to medicine and establishing general physiology as a distinct discipline. His classic work, Introduction to the Study of Experimental Medicine, was published in 1865. He was elected to the Académie Française in 1869 for this work.
