BERLIN (AP) — A German government-backed foundation says it is giving researchers access to photos from albums of the art company of Hildebrand Gurlitt, a dealer who traded in works confiscated by the Nazis and the father of collector Cornelius Gurlitt.

The German Lost Art Foundation has been tasked with researching the origin of art hoarded by Cornelius Gurlitt, who died in 2014. He had kept over 1,200 works at his Munich apartment and 250 more at a property in Salzburg, Austria.

The foundation said Friday some 600 photos from 1936-41 from Hildebrand Gurlitt's art company can now be viewed at Germany's Federal Archives — along with other photos of artworks.

It said it's also working to make thousands of written documents from Cornelius Gurlitt's estate available at the archives in May.
