Was Einstein's brain larger than average?


Quick Answer

There has been some scientific disagreement on the subject of Albert Einstein's brain. When he died in 1955, his brain was inspected by pathologist Dr. Thomas Harvey, who didn't see anything out of the ordinary. Years later, scientists would revisit Einstein's brain and find that it was more extraordinary in its makeup than Dr. Harvey initially claimed.

In 1999, a study led by Sandra F. Witelson examined the samples of Einstein's brain that Dr. Harvey preserved. The study found that Einstein's brain lacked a specific fold known as the parietal operculum, and that other parts of the brain, including those that deal with mathematical thinking, were enlarged, perhaps as a result of the missing parietal operculum.

Another study published in 2013 showed that Einstein had a higher-than-average share of corpus callosum, which helps the brain's two hemispheres communicate. These factors may have helped make Einstein more intelligent, but overall, his brain was of a normal size.
