Nobel medal is sold for charity

A Nobel Prize medal given to a pioneering scientist who travelled to the UK having fled Nazi Germany is to be sold at auction.

All proceeds from the sale will go to a Trust helping refugee scientists.

Hans Krebs, who died in 1981, won the prize for medicine in 1953 for his work on how food is converted into energy.

As a Jew, he fled Germany in the 1930s and worked at Cambridge and Sheffield Universities. The medal is expected to sell for around £350,000 on July 14.
