At the end of Stranger Things Season 2 episode 2, the mysterious noise in the trashcan outside Dustin's house wasn't revealed to be some kind of murderous creature, along the lines of a Thesselhydra. Instead, it was the world's oddest looking amphibian, a cross between a slug, a frog and, well, something just a touch slimmer, which was perfect since Dustin decided to transport it around in his Ghostbusting trap. However, his new friend also made him late for class, missing a history lecture about something just as creepy: Phineas Gage. But who was Phineas Gage? And why did Mr. Clarke choose this week to do a lecture on him? Please be aware: This post contains spoilers for Stranger Things Season 2.
Though the story Mr. Clarke tells the class (before Dustin so rudely interrupted with his late arrival) sounds like some sort of creepy science fiction, it's not. Like last season's grounding of Eleven's origin story in the MKUltra project, which was a real program the CIA ran in the 1950-1970s, Mr. Clarke's lesson on the day that Dustin brings a fantastic creature to school is based on a true set of events, one I actually remember learning about in school myself. (Though I didn't learn it in middle school, I learned about it high school psychology.)
Phineas Gage was born in the 1820s, and lived until 1860, passing away in his late 30s. Like most men of the time period who spent their lives building the great American railroad, his live might not have been one most remembered, except for a stunning accident that happened to him in 1848, when he was about 25 years old or so.
According to the Smithsonian,
Known as "The American Crowbar Case" (though it was a tamping rod, not an actual crowbar that went through the man's face and skull), Gage became a scientific sensation. Despite the obvious massive brain injury he suffered, he was not instantly killed. In fact, he regained consciousness pretty quickly, and stood up and walked around within a few minutes.
Later, doctors said he was seen to be throwing up, some of which included brain matter that had leaked out and dripped down his throat. Yet his mind was deemed clear and sharp, though his body kept twitching oddly.
Gage's recovery fascinated doctors of the time period. He would go through periods of total normality, only to wake up the next day and forget half his family and loved ones. This turned out to be due to an infection that set in from the wound. Once it was cleared out surgically, he recovered. He then went back to work and regained his normal life.
There was only one real issue as far as anyone could see, and that was a massive change in personality, not unlike what we today would associate with CTE. His sudden decline into epileptic seizures, emotional outbursts and memory loss about a decade after the accident also sounds right out of the CTE playbook.
So why was this talked about in Stranger Things? Perhaps to show how someone can survive a horrific trauma, but not return to their true self. Hm... doesn't sound too far off from Will Byers...
