Albert Einstein offered his wife his Nobel Prize as part of their divorce settlement.
After his marriage to Mileva Maric hit the rocks in the early 1910s, Einstein left his family, moved to Berlin, and started a new relationship with his cousin, Elsa. He and Maric finally divorced several years later in 1919. As part of their separation agreement, Einstein promised her an annual stipend plus whatever money he might receive from the Nobel Prize—which he was supremely confident he would eventually win. Maric agreed, and Einstein later handed over a small fortune upon receiving the award in 1922 for his work on the photoelectric effect. By then, he had already remarried to Elsa, who remained his wife until she died in 1936.
