When Albert Einstein, the unparalleled genius who reshaped our understanding of the universe, died on April 18, 1955, his legacy was already cemented in history. But what happened to his brain in the hours following his death is a tale as bizarre as it is controversial—a story of ambition, obsession, and a quest to unlock the secrets of genius. The organ that birthed the theory of relativity became the center of a decades-long odyssey, driven by a pathologist who risked everything to possess it.
A Genius Gone, A Brain Stolen
Born on March 14, 1879, in Ulm, Germany, Albert Einstein was a towering figure whose contributions to physics—most notably the theory of relativity—changed the world. His friendships with luminaries like Charlie Chaplin and his escape from Nazi Germany only added to his legend. So, when he succumbed to a burst aorta at age 76 in Princeton Hospital, the scientific community was abuzz with curiosity: could Einstein’s extraordinary intellect be explained by an equally extraordinary brain?
Enter Thomas Harvey, the pathologist tasked with performing Einstein’s autopsy. In a brazen act, Harvey removed Einstein’s brain without permission, driven by a mix of scientific curiosity and personal ambition. As Carolyn Abraham details in Possessing Genius: The Bizarre Odyssey of Einstein’s Brain, Harvey believed this organ could be the key to advancing his career. He didn’t stop at the brain—he also took Einstein’s eyes, gifting them to the physicist’s ophthalmologist.
The rest of Einstein’s body was cremated on April 20 in Trenton, New Jersey. When Einstein’s son, Hans Albert, discovered Harvey’s actions, he was furious but eventually allowed the brain to be studied, with one strict condition: any findings must be published in reputable scientific journals.
The Pathologist’s Obsession
Harvey’s fascination with Einstein’s brain became all-consuming. He meticulously documented it, weighing the organ at 1,230 grams—lighter than the average for men of Einstein’s age. He sliced it into 240 pieces, photographing each one and even commissioning a painting of the brain. His stated goal was scientific discovery, but his methods were unconventional, to say the least.
Harvey’s quest took him across the United States, distributing brain samples to researchers eager to study the mind of a genius. Even the U.S. Army received pieces, hoping to gain a scientific edge over the Soviet Union, which was reportedly collecting brains of its own during the Cold War era. “People were collecting brains—it was a thing,” Abraham noted.
But Harvey’s obsession came at a steep cost. His actions led to the loss of his job at Princeton, his medical license, and even his marriage. By 1978, he was living in Wichita, Kansas, where a stunned journalist discovered Einstein’s brain stored in a cider box under a beer cooler—a far cry from the reverence one might expect for such a historic organ.
Unraveling the Secrets of Genius?
In 1985, the first study on Einstein’s brain was published in Experimental Neurology, sparking intrigue with its findings. The study suggested that Einstein’s brain had an unusually high number of glial cells, which support and oxygenate neurons, potentially enhancing cognitive function. A 1996 study from the University of Alabama at Birmingham further claimed that Einstein’s neurons were more densely packed, possibly enabling faster information processing.
In 1999, analysis of Harvey’s photographs revealed that Einstein’s inferior parietal lobule—a region linked to visual and spatial thinking—was wider than average. A 2012 study went further, identifying an extra ridge in the mid-frontal lobe, associated with planning and memory. These findings fueled speculation that Einstein’s brain was physically distinct, perhaps explaining his unparalleled intellect.
But not everyone was convinced. Critics, like Pace University psychologist Terence Hines, dismissed these studies as “neuromythology.” Hines argued that studying a single brain—especially one as unique as Einstein’s—couldn’t definitively explain his genius. “You can’t just take one brain and say, ‘Ah-ha! This is what made Einstein special!’” he said. Neurologist Dr. Frederick Lepore, who contributed to the 2012 study, admitted the limits of their findings: “Where did general relativity come from? We have no idea.”
A Legacy in Fragments
The debate over Einstein’s brain continues, with no clear answers. Most of the brain was eventually returned to Princeton Hospital, but fragments remain scattered across institutions. The National Museum of Health and Medicine received the bulk of it after Harvey’s death in 2007, while Philadelphia’s Mütter Museum displays slides of the brain to this day, drawing curious visitors.
The saga of Einstein’s brain is a testament to humanity’s fascination with genius—and the lengths to which we’ll go to understand it. Was Harvey a visionary pursuing scientific truth or an opportunist chasing fame? Did Einstein’s brain hold the key to his brilliance, or is genius too complex to be reduced to neurons and ridges? One thing is certain: the story of what happened to Einstein’s brain after his death is as extraordinary as the man himself.
