Dr. William Beaumont and Alexis St. Martin

Dr. William Beaumont served at Fort Mackinac from 1820 to 1825.

On June 6, 1822, a shot rang out inside the American Fur Company’s retail store located on Mackinac Island’s Market Street. When the smoke cleared, Alexis St. Martin, a young French Canadian voyageur, lay bleeding on the floor. Although the exact cause of the accident has been lost to history, the immediate results were abundantly clear: St. Martin was grievously wounded, with a large hole blasted into the left side of his abdomen and the interior of his stomach exposed. Although St. Martin was not expected to survive, store patrons sent word to fetch Dr. William Beaumont, the post surgeon at Fort Mackinac and the only physician on Mackinac Island. Arriving minutes after the accident, Beaumont made St. Martin comfortable but judged his wound to be mortal. The doctor had St. Martin carried to the post hospital in the fort. To Beaumont’s amazement, St. Martin survived, and under the doctor’s care began healing. Together, Beaumont and St. Martin embarked upon a journey of scientific discovery that continues to shape medical care today.

Dr. Beaumont’s book.

 As St. Martin recovered from the accident, the wound slowly healed. However, instead of closing, the hole into his stomach fused to his abdominal muscles, creating a permanent opening. Beaumont realized this presented a unique opportunity to observe the digestive process inside a living person, and at the urging of the surgeon general of the army began making informal notes about what he could see inside St. Martin’s stomach as it worked to digest food. These initial observations occurred at Fort Mackinac in 1824, but grew into a series of formal experiments carried out periodically at other posts until 1833. By the time the final experiments concluded, Beaumont had gained a much clearer understanding of the human digestive process, publishing his findings as Experiments and Observations on the Gastric Juice and the Physiology of Digestion. Although other physicians and scientists had previously contributed to our understanding of how our stomachs work, St. Martin’s injury allowed Beaumont to make critical observations about the mechanical and chemical processes which occur during the digestive process.

 To mark the 200th anniversary of the accident that set Beaumont and St. Martin on their path of discovery, a new gallery exhibit is being installed in the American Fur Company Retail Store. Opening on June 4, this new exhibit tells the story of the accident and subsequent research that transformed Beaumont into the “father of gastric physiology.” Admission to the new exhibit is included with tickets to Fort Mackinac and the Mackinac Island Native American Museum at the Biddle House. We hope you’ll join us soon to see this exciting new addition and learn more about Mackinac Island’s own contribution to medical science.

Biddle House Update

As you may have heard, we’re currently in the process of updating the Biddle House to include the Mackinac Island Native American Museum. This new exhibit, which tells the continuing story of the Anishnaabek on Mackinac Island and in the surrounding Straits of Mackinac region, will open in early summer 2020. To get the building ready for the new exhibit, the Biddle House itself is currently undergoing a variety of restoration work. (more…)

Old Mackinac Point Lighthouse Exhibit Update

For the first time in the history of Old Mackinac Point Lighthouse, the second floor of the house will be available to the public. As part of our Mackinac Parks: 125 celebration, a new exhibit will debut on the second floor of the house exploring the domestic life of the Marshall’s in the early 1910s. Join Curator of History Craig Wilson as he provides a construction update. Old Mackinac Point Lighthouse, and the new exhibit, will open May 7, 2020.

On this day: Capture of Fort Mackinac, July 17, 1812

Just over 200 years ago, Lieutenant Porter Hanks of the U.S. Regiment of Artillery awoke to a particularly unpleasant surprise. As July 17, 1812 dawned, Hanks learned that not only was the United States at war with Great Britain, but, more concerning, that a force of 600 British soldiers, Native American warriors, and Canadian militiamen stood poised to attack Fort Mackinac.

What’s new at Fort Mackinac?

It may not seem like it with so much snow on the ground, but summer is steadily approaching. With less than two months to go before Fort Mackinac opens for the 2019 season, we’re hard at work on two brand new exhibits which will greet visitors to the fort this summer. (more…)
