American Fur Company Store
On June 6, 1822, Alexis St. Martin (1804 ~ 1889), a French Canadian voyageur, was accidentally shot in the American Fur Company store located on this site.. Dr. William Beaumont (1786 ~ 1853), The Fort Mackinac post surgeon nursed St. Martin back to health. St. Martin's wound healed, leaving a permanent opening into his stomach. Through this opening Beaumont compared the digestibility of foods, recorded the temperature of the stomach under different conditions, and extracted and analyzed gastric juices. Beaumont conducted the first of 250 experiments with St. Martin in 1825 in the Officers' Stone Quarters at Fort Mackinac. Eight years later he published a groundbreaking book on his discovery of the digestive process.
