Bernard, Claude (1813–1887)
Claude Bernard was a French physiologist regarded as the father of experimental
medicine. Following the work of William Beaumont he opened artificial fistulas in animals to study their digestive
systems. He demonstrated the role of the pancreas in digestion, discussed the presence and
function of glycogen in the liver (1856), and in 1851 reported the existence of the vasomotor nerve.
