The Man Who Got Better

In 1848, an iron bar blew through a railroad foreman's skull and out the other side, and he kept talking. The textbook version of what happened to him next took a century and a half to fall apart.

On the afternoon of September 13, 1848, a twenty-five-year-old railroad foreman named Phineas Gage was kneeling beside a hole drilled into a rock outcropping near Cavendish, Vermont, doing a job he had done hundreds of times before. He and his crew were clearing a path for the Rutland & Burlington Railroad, and the method was simple and dangerous in equal measure: drill a hole, pour in blasting powder, lay a fuse, cover the powder with sand, and tamp it all down firmly with an iron rod before lighting the fuse. Gage had his own tamping iron, custom-made at a local blacksmith’s to his own specifications — three feet seven inches of iron, tapered at one end, as thick around as a broom handle, weighing in at roughly thirteen and a half pounds.

Something went wrong with the order of operations that afternoon. Accounts differ on exactly what — maybe the sand was never poured, maybe Gage was distracted by his men behind him — but the result was not in dispute. The tamping iron struck the rock, sparked, and ignited the powder directly beneath it, with the iron still in Gage’s hand and his head directly above the hole.

The blast drove the iron rod up and out of the hole like a bullet fired from a gun. It entered just under Gage’s left cheekbone, passed behind his left eye, tore through the front of his brain, and exited through the top of his skull, continuing on to land some eighty feet away, “smeared with blood and brain,” as one description had it.

Gage fell backward. And then — this is the detail that made the case famous before anyone had the slightest idea what to make of it — he got back up.

“I think I will shake hands all round”

Within a few minutes, Gage was talking. His men carried him to an oxcart; he reportedly sat upright for most of the mile-long ride into town, and when he arrived he climbed out of the cart largely under his own power. A local doctor, Edward Williams, examined him first and later wrote that he found the account hard to believe even with the patient sitting in front of him — Gage, according to Williams, greeted the small crowd that had gathered by saying something to the effect of “here is business enough for you.” Blood and what Williams took to be brain matter were visible through the wound at the top of the skull.

The physician who would actually treat Gage, and whose name would become permanently bound to the case, was a local doctor named John Martyn Harlow. Harlow cleaned the wound, which exposed an opening at the crown of Gage’s head roughly three and a half inches across, removed bone fragments, and settled in to watch his patient probably die. Infection was the expected killer in 1848; antiseptic practice didn’t exist yet. Gage did develop a severe fungal infection in the exposed brain tissue and spent weeks slipping in and out of a semi-comatose state, at one point so unresponsive that his family was told to prepare for the end. He pulled through anyway. By late November, ten weeks after the accident, Harlow pronounced him recovered enough to go home. Gage walked.

Harlow wrote up the case for the Boston Medical and Surgical Journal, publishing a short account in December 1848. It attracted the attention you’d expect — a man survives an iron rod through the frontal lobes of his brain, something physicians of the era considered essentially impossible, since the brain was widely assumed to be too delicate and too essential an organ to survive that kind of violation at all. Henry Jacob Bigelow, a prominent Harvard surgeon, traveled to Vermont to examine Gage himself and later presented the case in Boston, instructing Gage to demonstrate, among other things, that he could insert the original tamping iron — which Gage now carried with him as something between a souvenir and a credential — directly into the hole in his own skull.

That 1848 report said almost nothing about Gage’s mind or personality. It was a report about a body that had defied the rules of anatomy. The far more famous part of the story — the part that made Phineas Gage one of the two or three most cited case studies in the history of psychology — didn’t exist yet. It wouldn’t exist for another twenty years.

The paragraph that launched a thousand textbooks

Harlow lost track of Gage for a long stretch after his recovery. Gage left Vermont, and by most accounts spent much of the 1850s working — including, according to several biographical sketches assembled decades later, an extended stint driving long-distance stagecoaches in Chile, a job that by its nature demanded sustained attention, route-planning, and dealing with strangers and schedules day after day. Precise dates for this period are thin in the surviving record, but the general shape — that Gage held skilled, demanding jobs for years after the accident — is well corroborated.

By the late 1850s his health was failing. He moved to San Francisco to live near his mother and sister. In February 1860 he began having epileptic seizures, almost certainly a late consequence of the brain injury twelve years earlier, and in May of that year he died during a cluster of these seizures. He was thirty-six.

Harlow learned of Gage’s death after the fact, arranged with the family to exhume the body, and had the skull — along with the tamping iron, which had been buried with Gage — shipped back to him. It was only now, in 1868, twenty years after the accident and eight years after Gage’s death, that Harlow sat down and wrote the report that would make the case immortal. Presented to the Massachusetts Medical Society that June, it included a passage describing what Gage had supposedly been like after the accident, based entirely on Harlow’s own recollection and secondhand reports gathered from Gage’s family and acquaintances years after the fact. Gage, Harlow wrote, had become “fitful, irreverent, indulging at times in the grossest profanity (which was not previously his custom), manifesting but little deference for his fellows,” impatient of restraint or advice when it conflicted with his own wishes, and so changed that friends and acquaintances said he was “no longer Gage.”

That handful of sentences is, essentially, the entire contemporary evidentiary record for Gage’s post-accident personality. Historian Malcolm Macmillan, who spent years tracing every surviving document related to the case, found that the whole of it amounts to fewer than two hundred words, written by one man, two decades after the events it describes, with no supporting testimony, diary entries, or independent observation from anyone who actually knew Gage during the years in question.

It didn’t matter. The story was too good. Over the following century, as psychology and neuroscience textbooks reached for a vivid, human illustration of what the brain’s frontal lobes actually do, Gage became the default answer. Each retelling tended to sharpen the picture a little further: the mild-mannered, responsible foreman transformed by his injury into a foul-mouthed, impulsive, unemployable drifter, unable to hold a job, unable to plan, a cautionary tale in a human body about what happens when the seat of judgment is physically destroyed. By the twentieth century, some popular accounts had Gage reduced to working as a circus sideshow attraction, exhibiting his own skull-piercing injury for money, a broken man trading on his own trauma. It was, in the literal sense, the stuff of legend — a case passed down and amplified through generations of secondhand retelling, the historical equivalent of a game of telephone played by several thousand psychology professors.

What Macmillan actually found

Macmillan’s research, published with Matthew Lena in a 2010 paper titled “Rehabilitating Phineas Gage,” systematically went after every claim in the mythologized version and checked it against whatever primary evidence still existed. Almost none of it held up as stated.

The sideshow story appears to be true only in a much narrower sense than usually told — Gage did, for a time, display himself and his iron, including at Barnum’s American Museum in New York, but this reads less as the last resort of a ruined man and more as a reasonable thing for someone to do when they happen to be the most medically astonishing person alive and there’s a line of people willing to pay to see it. More importantly, it was brief, and it was followed by years of ordinary, demanding work. A man who spends the better part of a decade driving stagecoaches on set routes and schedules, dealing with passengers and horses and the logistics of long-distance travel in 1850s South America, is not a man who has lost the capacity to plan, concentrate, or function around other people — which is precisely the deficit the textbook version of Gage was supposedly meant to demonstrate.

Macmillan’s argument isn’t that Harlow invented the personality changes outright, or that the accident left Gage completely unaffected. It’s that the real, observed trajectory looks far more like a man who suffered a severe and possibly lasting change immediately after the trauma — understandable, given what had just happened to him — and who then substantially recovered, going on to live and work for another dozen years, only for a single, late, secondhand summary of his worst period to be mistaken, by everyone who came after, for the whole and permanent truth of his life after the accident.

This is, to be clear, still a live argument rather than a fully settled one. Some neuroscientists and historians have pushed back on just how much weight to put on Macmillan’s reconstruction, given how thin the surviving record is in either direction — if there isn’t much evidence for the “ruined man” story, there also isn’t an abundance of it for the “full recovery” story. What’s not seriously disputed anymore is that the clean, dramatic, maximally instructive version — delicate, responsible foreman goes in, feral impulsive wreck comes out, forever — was never supported by the evidence Harlow actually provided. It was built afterward, retelling by retelling, because it made a better lesson than the messier and more ambiguous truth.

The man in the photograph

For more than 150 years, there was no known image of Phineas Gage. There were written descriptions, the skull itself — preserved, along with the tamping iron, at Harvard Medical School’s Warren Anatomical Museum, where both remain on public display — and a plaster life mask made of his face. But no photograph, which was itself a little strange given that Gage lived well into the daguerreotype era and was, by any measure, one of the more photographable people of his time.

That changed in 2009. Jack and Beverly Wilgus, a couple who collected antique photographs, had owned a sixth-plate daguerreotype for years, cataloguing it as a portrait of a disfigured, one-eyed whaler holding a harpoon — a reasonable guess, given the image showed a man with a badly scarred, asymmetrical face holding a long metal implement. They had posted the image online, and a commenter eventually suggested a different explanation: that the “harpoon” was actually a tamping iron, and the man was Phineas Gage.

The Wilguses took the idea seriously enough to travel to Harvard with the photograph and compare it directly against Gage’s life mask and the engraved tamping iron in the Warren Museum’s collection. The match held up. The scarring, the asymmetry of the face, the object in the man’s hands — all of it was consistent, and the case was published the same year in the Journal of the History of the Neurosciences as, in all likelihood, the only photograph of Phineas Gage ever taken. The daguerreotype has since joined the skull and the iron at Harvard, which means that the three physical traces left behind by one of the strangest afternoons in the history of medicine — the weapon, the wound, and now the face — ended up, by complete coincidence of provenance, in the same drawer.

It’s a fitting enough postscript for a case that has spent a century and a half being pieced back together in exactly this way: not through some single dramatic discovery, but through people — doctors, historians, a couple with an old photograph and an open mind about what they might actually be looking at — slowly checking the story against whatever evidence happened to survive, and finding, each time, that the truth was a little stranger, a little less tidy, and a little more interesting than the version that had been handed down.
