The Man With the Window in His Stomach

Beaumont's experiments with St. Martin founded modern gastric physiology, and the research still informs how we understand digestion today. The story also asks a question that hasn't gone away: what do we owe the people whose bodies made the science possible?

In 1822, a musket misfired at Fort Mackinac, and a French-Canadian fur trader named Alexis St. Martin ended up with a hole in his stomach that never healed. His surgeon, US Army doctor William Beaumont, recognised an extraordinary opportunity. St. Martin, one suspects, saw something rather less appealing.

The wound left a permanent gastric fistula: a direct, lasting opening into the living stomach. For the first time in history, a human digestive system could be observed at work, in real time, without any of the inconveniences that normally come with access to someone’s internal organs. Beaumont spent years conducting experiments through the opening, watching digestion happen from the outside.

The science that followed was genuinely revolutionary. Beaumont’s work transformed our understanding of gastric physiology, and the research he produced helped lay the groundwork for modern digestive science.

The less comfortable part of the story is the relationship between the two men. St. Martin was not a willing volunteer in any uncomplicated sense. A working-class fur trader and a military surgeon do not come to an experiment as equals, and the episode does not pretend they did. The knowledge was real, and the imbalance was real, and both things matter.

The Rest of 6 June

The date has form for the unexpected. In 2002, a near-Earth asteroid exploded over the Mediterranean and went almost entirely unnoticed. These events happen more often than is comfortable to think about.

On 6 June 1985, an exhumation in Brazil confirmed that Josef Mengele had died there. Not a tidy conclusion, as conclusions go, but a conclusion.

And in 1933, New Jersey opened the world’s first drive-in cinema. Someone had to do it first, and it turned out to be New Jersey.

Why Listen?

Today’s episode is about survival, improvisation, and the things that were never supposed to happen. It asks, quietly, what we owe the people whose bodies made the science possible. That question has not gone away, and ten minutes in the morning seems a reasonable amount of time to sit with it.

In this episode

  • The Man With the Window in His Stomach The story of Alexis St. Martin, who survived a catastrophic musket wound in 1822 that left a permanent opening into his stomach. Surgeon William Beaumont conducted years of experiments through this gastric fistula, revolutionising the understanding of digestion whilst St. Martin became an involuntary research subject. Also covered: the 2002 Mediterranean asteroid explosion that went largely unnoticed, the 1985 exhumation confirming Josef Mengele’s death, and the 1933 opening of America’s first drive-in cinema.

The Day the US Postal Service Tried Missile Mail

On 8 June 1959, the United States Navy fired a Regulus cruise missile from the submarine USS Barbero off the coast of Florida. Inside, replacing the nuclear warhead, was a postal canister containing three thousand letters. Postmaster General Arthur Summerfield watched the launch and declared it of historic significance to the peoples of the entire world. The missile travelled roughly one hundred miles, landed at Naval Air Station Mayport, and the mail was retrieved and stamped with a special ‘MISSILE MAIL’ postmark. Summerfield genuinely believed this was the future of postal delivery, envisioning coast-to-coast routes by cruise missile. The programme was never repeated. Also on this date: Robespierre presided over the Festival of the Supreme Being in 1794, weeks before his own execution; banker Alexander Fordyce fled to France in 1772, triggering a credit crisis across Britain and the Dutch Republic; two pilots died when an F-104 Starfighter collided with an XB-70 Valkyrie in 1966; and the descendants of the Bounty mutineers arrived at Norfolk Island in 1856 to begin a new settlement.

Carrie Nation's Hatchet and the Day of the Tiles

On 7 June 1899, Carrie Nation walked into a saloon in Kiowa, Kansas, carrying rocks, and smashed the bottles. She was not making a point. She was enforcing the law. Kansas was a dry state, but the saloons were open, and local officials were looking elsewhere. Nation, a committed temperance campaigner whose first husband had been an alcoholic, decided that if the system would not fix the problem, she would. Her direct action, which later became synonymous with her trademark hatchet, made her one of the most recognisable women in turn-of-the-century America. She was arrested repeatedly, welcomed the platform, and argued that if laws existed and were not enforced, citizens had a right to enforce them. Also on this date: Graceland opened to the public in 1982, turning Elvis Presley’s private Memphis home into one of America’s most visited sites. In 1971, the US Supreme Court ruled in Cohen v. California that offensive speech is constitutionally protected. And in 1788, during the Day of the Tiles in Grenoble, French citizens threw roof tiles at royal troops, marking an early spark of the French Revolution. Each story shares a common thread: people who stopped waiting politely for change.

The Last Transit of Venus and the Stories of 5 June

On 5 June 2012, millions watched Venus cross the face of the Sun for the last time in any living person’s lifetime. The next transit won’t occur until 2117. This rare celestial event once sent Captain Cook to Tahiti in 1769 and helped unlock the true scale of the solar system. But the fifth of June holds other remarkable stories: in 1983, the Soviet cruise ship Aleksandr Suvorov collided catastrophically with a railway bridge on the Volga River, killing over a hundred passengers. In 1995, physicists at the University of Colorado created the first Bose-Einstein condensate, a state of matter predicted by Einstein seventy years earlier. In 1956, Elvis Presley’s hip-swivelling performance of Hound Dog on The Milton Berle Show scandalised critics and ignited rock and roll on primetime television. And in 1949, Orapin Chaiyakan became the first woman elected to Thailand’s Parliament. From planetary mechanics to cultural flashpoints, this episode explores the moments that still resonate from a single day in history.
