de Hevesy, who had Jewish grandparents, later had to flee Copenhagen, but after the war, he returned to his lab, to find the solution undisturbed on the shelf. He precipitated the gold out of the acid and sent the gold to Stockholm, where the Nobel Society then recast the medals using the recovered gold and returned them to the two laureates.
de Hevesy also won his own Nobel prize in 1943.
