American Fur Company Store and Dr. Beaumont Museum

ABOUT

On this site in 1822, Alexis St. Martin, a voyageur, was injured by an accidental gunshot wound. The unusual healing of the wound allowed Dr. William Beaumont, Fort Mackinac’s post surgeon, to conduct experiments on how the human stomach worked. It was this work that led us to our understanding of how the human digestive system works today.
