Einstein gave his Nobel money to his first wife and asked to be cremated in secret, and the pathologist kept his brain for decades

On 12 June 1918 Albert Einstein signed an agreement with his first wife, Mileva Marić. If they divorced and he won the Nobel Prize, the money would be hers, held in a Swiss bank, and would pass to their two sons if she died or remarried. They divorced in 1919. He won the 1921 prize and transferred the money. It later paid for care of their younger son, who had schizophrenia. Einstein's will of 18 March 1950 made Otto Nathan sole executor and named Nathan and his secretary Helen Dukas trustees of his literary estate. All rights were to pass in the end to the Hebrew University of Jerusalem. Einstein died at Princeton Hospital on 18 April 1955. He had asked to be cremated and his ashes scattered in secret. During the autopsy the pathologist Thomas Harvey removed his brain. Harvey lost his hospital job, cut the brain into about 240 pieces and kept them in jars for decades, including in Wichita, Kansas. Nathan scattered the ashes. In 1982 the estate transferred all literary rights to the Hebrew University. Pieces of the brain are now at the pathology department of the Princeton medical centre at Plainsboro and at the Mütter Museum in Philadelphia.
