"When the scientist died in 1955 at age 76, Thomas Harvey, the pathologist who autopsied him, took out Einstein's brain and kept it. Harvey sliced hundreds of thin sections of brain tissue to place on microscope slides and also snapped 14 photos of the brain from several angles. Harvey presented some of the slides, but kept the photos secret in order to write a book about the physicist's brain. The pathologist died before finishing his book, however, and the photos remained hidden for decades. But in 2010, after striking up a friendship with one of the new study's co-authors, Harvey's family donated the photos to the National Museum of Health and Medicine . . . Falk's team began analyzing the photos in 2011. " They found some interesting differences."
