In 1848, 25 year old Phineas Gage was laying tracks for a railroad company he was working for. The men he supervised and the company as a whole characterized him as a “efficient and capable” employee who was responsible, even-tempered and likable. His personality completely altered with an unfortunate accident where a long tamping iron pierced his left cheek straight through the top of his skull. He managed to stay alive, yet suffered from having a 1.5 inch hole through his brain’s frontal lobes. After the accident, he could not work anymore not due to loss of motor skills but a drastic change in temperament. He still remained nimble, alert and able to speak and think, yet he became disrespectful, profane, impulsive and indecisive. His personality changed so profoundly due to his paucity to experience appropriate emotion. At 38, he died of a brain seizure.
