Einstein's brain was not preserved after his death in 1955, but this fact was not revealed until 1978.
The brain of Albert Einstein has been a subject of much research and speculation. Albert Einstein's brain was removed shortly after his death.[1] His apparent regularities or irregularities in the brain have been used to support various ideas about correlations in neuroanatomy with general or mathematical intelligence. Studies have suggested an increased number of glial cells in Einstein's brain.[2][3]
