Phineas Gage

In 1848 an iron rod blasted through a railway foreman's head. He survived — but 'was no longer Gage'. The most famous case in neuroscience, and how its story grew in the telling.

On 13 September 1848, near Cavendish, Vermont, a 25-year-old railway construction foreman named Phineas Gage was packing explosive powder into a hole in rock with a tamping iron — a rod about 1.1 metres (3 feet 7 inches) long and 6 kilograms (13¼ pounds) in weight. A spark ignited the powder. The rod shot up through his left cheek, behind his left eye, out through the top of his skull, and landed some 25 metres away.

He survived

Astonishingly, Gage was conscious within minutes and spoke to the doctor who treated him, John Harlow. He survived an infection and was well enough physically to return to his family within months. The rod had destroyed much of his left frontal lobe.

"No longer Gage"

In 1868 Harlow reported that Gage's personality had changed. Once efficient and well-balanced, he had become "fitful, irreverent, indulging at times in the grossest profanity", impatient and unable to stick to plans — so much so that his friends said he was "no longer Gage". The case became a key piece of evidence that the frontal lobes are involved in personality, social behaviour and self-control.

The legend versus the record

The psychologist Malcolm Macmillan, who spent decades studying the sources, showed that later accounts greatly exaggerated the changes — painting Gage as a permanent drifter and brute. In fact, Gage later worked for years as a stagecoach driver in Chile, a demanding job requiring planning and social skill, suggesting substantial recovery. He died in 1860, after a series of seizures. His skull and the tamping iron are displayed at Harvard's Warren Anatomical Museum.

The Gage case still teaches two lessons: the frontal lobes shape who we are — and famous stories need checking against the evidence.
