A pair of molar roots, the brass foot of an alarm clock, buffalo nickels and Mercury dimes, a half-dollar dated 1892. A crucifix with several rosary beads still attached; the metallic letter Z from a toy airplane; a handful of pebbles formed from hardened pus. Safety pins, each splayed open, an alphabet of angles; bones, some slender as a lock of hair. A poker chip, a coffee berry (unroasted), a Perfect Attendance pin.

Each object found its unhappy place in a person’s trachea, larynx, bronchus, esophagus, stomach, pleural cavity, lung tissue, pharynx or tonsil. Each was removed—and kept—by a laryngologist with the improbable name of Chevalier Quixote Jackson. The physician, who worked in Pittsburgh, then Philadelphia, during the late nineteenth and early twentieth centuries, was rarely paid by his patients; his only request was that he be allowed to keep what he called the “fbdy,” short for “foreign body.” His collection of more than 2,000 objects, which he donated to Philadelphia’s Mütter Museum in the early 1920s—and is perhaps overshadowed by the museum’s more grotesque medical oddities—is undergoing a complete refurbishment, the first phase of which debuted in February.

“How does someone swallow that?” is a question that many of the objects herald, and Jackson’s meticulous records show that the answers were as various as the items themselves: “Put toy in his mouth to hide it from sister.” “Suffering of melancholy.” “Alone on floor with pile of buttons.”

So determined was Jackson to keep every fbdy that when an angry father threatened to kill “that Doctor Jackson who stole my quarter,” which his son had swallowed, Jackson, by the physician’s own recollection, subdued the man with a gentle voice and refused. Though the boy suffered a broken arm and a bloody lip at his father’s hands for not recovering the coin, Jackson stood firm, offering the family a half-dollar instead.

Yet Jackson should be as much remembered for his pioneering work as for his obsessive collecting. He went at each bit of peanut kernel stuck in a trachea, each safety pin (which he enjoyed calling “danger pins”) in a stomach, as a newly challenging Gordian knot, each solution carefully described in the hundreds of books and articles he wrote during his 93 years. Before Jackson, only two patients out of a hundred might successfully cough up, regurgitate or excrete a foreign body, and surgery resulted in death in 98% of all cases. His construction of the bronchoscope in 1899 (it was not the first, but it came to be considered one of the best) was a major advance. Jackson developed thousands of instruments and saved as many lives; his students went on to save half a million more.

Trained as a visual artist, Jackson was known as much for his “chalk talks”—lively lectures accompanied by colorful sketches he would make on the spot—as for fbdy removal. In a 1938 interview, Jackson professed his fascination with “the never-ending, awe-inspiring sights, in the depths of the bronchi…. Still another fascination was the play of colors, so beautiful to paint for illustrations and so interesting to draw with chalk for demonstration to the students.”

Both in his fbdy collection and in his paintings, perhaps we might glimpse the same beauty he saw.
