Einstein's master brain

Albert Einstein's brain has often been a subject of research and speculation. Einstein'sbrain was removed within seven and a half hours of his death. The brain has attracted attention because of Einstein's reputation for being one of the foremost geniuses of the 20th century, and apparent regularities or irregularities in the brain have been used to support various ideas about correlations in neuroanatomy with general or mathematical intelligence. Scientific studies have suggested that regions involved in speech and language are smaller, while regions involved with numerical and spatial processing are larger.Other studies have suggested an increased number of Glial cells in Einstein's brain


Whether Einstein's brain was removed and preserved after his death in 1955 with his permission is a matter of dispute. Ronald Clark's 1979 biography of Einstein said that "he had insisted that his brain should be used for research and that he be cremated", but more recent research has suggested that this may not be true at all, and that the brain was removed and preserved with neither Einstein's prior permission nor the permission of his close relatives.


Einstein's autopsy was conducted in a lab at the University of Pennsylvania by pathologist Thomas Stoltz Harvey at Princeton shortly after his death. Harvey then removed, weighted and dissected into several pieces Einstein's brain; some of the pieces he kept to himself while others were given to leading pathologists.
Harvey also removed Einstein's eyes, and gave them to Henry Abrams.He was fired from his position at Princeton Hospital shortly thereafter for refusing to relinquish the organs.
