Hard number: Seeking owners

It’s not known whether these works were among the hundreds of thousands that the Nazis looted – especially from Jews – during their time in power, but in displaying these pieces, the museum hopes that the public can identify their original owners. Perhaps the most famous lost painting of this kind was Gustav Klimt’s “The Woman in Gold”, which was rediscovered in 2006. It now hangs in New York City’s Neue Galerie. France has faced criticism for being too slow to return artworks that were stolen by Nazis.
