Final years
In 1948, Einstein served on the original committee which resulted in the founding of Brandeis University. In 1952, the Israeli government proposed to Einstein that he take the post of second president. He declined the offer, and is believed to be the only United States citizen ever to have been offered a position as a foreign head of state.
He died at 1:15 AM[34] in Princeton hospital[35] in Princeton, New Jersey, on April 18, 1955 at the age of 76 from internal bleeding, which was caused by the rupture of an aortic aneurism, leaving the Generalized Theory of Gravitation unsolved. He was cremated without ceremony on the same day he died at Trenton, New Jersey, in accordance with his wishes. His ashes were scattered at an undisclosed location.
An autopsy was performed on Einstein by Dr. Thomas Stoltz Harvey, who removed and preserved his brain. Harvey found nothing unusual with his brain, but in 1999 further analysis by a team at McMaster University revealed that his parietal operculum region was missing and, to compensate, his inferior parietal lobe was 15% wider than normal.[36] The inferior parietal region is responsible for mathematical thought, visuospatial cognition, and imagery of movement. Einstein's brain also contained 73% more glial cells than the average brain
