When Franck left Denmark in 1935, he did not take his Nobel medal with him. To prevent it from falling into the hands of the invading Nazis in 1940, George de Hevesy dissolved the medal in aqua regia. Recast from the original precipitate after the end of the war, it was presented to Franck a second time in 1952..
