William Beaumont

Born 21 Nov 1785; died 25 Apr 1853 at age 67. American army surgeon who was the first person to observe and study human digestion as it occurs in the stomach. As a young army surgeon stationed on Mackinac Island in Michigan, Beaumont was asked to treat a shotgun wound. The wound was "more than the size of the palm of a man's hand," Beaumont wrote. The patient, Alexis St. Martin, survived but was left with a permanent opening into his stomach from the outside. Over the next few years, Dr. Beaumont used this crude fistula to sample gastric secretions. He identified hydrochloric acid as the principal agent in gastric juice and recognized its digestive and bacteriostatic functions. Moreover, many of his conclusions about the regulation of secretion and motility remain valid to this day.
