Phineas was a young man that blew holes in mountains to build railroads. This is him right before a terrible accident.
Straight through your head
Phineas was about to blow up a rock when something distracted him. He had already lit the fuse to the powder and forgot to put in the sand to plug the hole. His tamping iron was still in the hole when the fuse lit, causing it to get shot up, straight through his head.
Never the Same Again
The other workers brought alive, conscious Phineas into town to see the doctor. Phineas called for his time book and then asked to see him, but it turned out the doctor wasn't in town so the doctor from the other town had to come over.
One the doctor arrived, he discovered that the rod had gone right through Phineas's head. It went in through his cheek, behind his eye, and out his forehead. The doctor bandaged the holes and told Phineas to get some rest and let the wound heal.
The rod had gone through his frontal lobe, which is responsible for decision making and thinking. Because it went through there he had many mental disabilities and was never the same again
11 years later, Phineas died of complications. His accident gave science a much better understanding of how the brain works.
