George de Hevesy

From Wikipedia, the free encyclopedia

George Charles de Hevesy (born as Hevesy György, also known as Georg Karl von Hevesy) (August 1, 1885 in Budapest – July 5, 1966) was a Hungarian physical chemist who was important in the development of the tracer method where radioactive tracers are used to study chemical processes, e.g., the metabolism of animals. For this he was awarded the Nobel Prize in Chemistry in 1943.

When Germany invaded Denmark in World War II, he dissolved the gold Nobel Prizes of Max von Laue and James Franck into aqua regia to prevent the Nazis from stealing them. He placed the resulting solution on a shelf in his laboratory at the Niels Bohr Institute. After the war, he returned to find the solution undisturbed and precipitated the gold out of the acid. The Nobel Society then recast the Nobel Prizes using the original gold.[1]

In 1923 he was a co-discoverer of Hafnium, with Dirk Coster.

George de Hevesy married Pia Riis in 1924. They had one son and three daughters.
