Phineas Gage, the Railroad Foreman Who Survived a 13-Pound Iron Rod Through His Skull in 1848

Phineas Gage, 25, was a blasting foreman on the Rutland and Burlington Railroad, cutting a roadbed through rock near Cavendish, Vermont. His employers considered him their most capable man. His tool of trade was a custom-made tamping iron: 3 feet 7 inches long, 1.25 inches in diameter, 13.25 pounds, tapered to a point.

13 September 1848

At about 16:30, Gage was setting a charge — bore a hole, add powder and fuse, then tamp sand over it. Distracted for a moment, he brought the iron down before the sand was in. The iron struck rock, sparked, and the powder detonated.

The rod entered point-first under his left cheekbone, passed behind his left eye, through the front of his brain, and exited the top of his skull, landing some 25 metres away “smeared with blood and brain.” Gage was thrown onto his back. Within minutes he was speaking. He rode into town sitting upright in an ox cart and greeted the local physician from the porch of his hotel: “Doctor, here is business enough for you.”

Dr John Martyn Harlow dressed the wound, navigating weeks of infection, fungal protrusion, and a coma-like decline that had a coffin reportedly prepared. By November Gage was walking around town. He had lost the sight of his left eye but by any contemporary standard should have been dead.

”No longer Gage”

Harlow’s 1868 follow-up report contains the observation that made the case immortal: the balance “between his intellectual faculties and animal propensities” seemed destroyed. The once shrewd, energetic foreman was now “fitful, irreverent,” profane, impatient of restraint, “devising many plans of future operation, which are no sooner arranged than they are abandoned.” His friends said he was “no longer Gage.” The railroad would not take him back.

The details rest almost entirely on Harlow’s brief accounts, and modern scholarship — particularly Malcolm Macmillan’s — argues the change was likely less total and less permanent than textbooks claim: Gage later worked steadily for years as a stagecoach driver in Chile, a demanding, socially competent job.

Gage died in San Francisco on 21 May 1860 after a series of seizures. There was no autopsy, but in 1867 Harlow arranged the exhumation of the skull, which sits today — with the tamping iron — in Harvard’s Warren Anatomical Museum. The case became the founding exhibit for the idea that the frontal lobes govern personality and self-control.
