Swiss museum to accept Nazi art collection
A Swiss museum says it will accept a priceless collection of long-hidden artwork that includes masterpieces stolen by Nazi Germany.
An official with the Bern Art Museum said Monday in Berlin that the museum would accept the collection. But, he said, it would also work to return any art stolen from Jews during World War Two.
In 2012, German authorities seized more than 1,200 art works from the Munich home of Cornelius Gurlitt. Mr. Gurlitt was the son of an art dealer who worked for Adolf Hitler to help steal works from museums and Jewish collectors. Many of the Jewish collectors died in the Nazi gas chambers.
Cornelius Gurlitt died in May at the age of 81.
