Gurlitt, who died in 2014, was the son of one of the dealers Goebbels chose to sell confiscated “degenerate” artworks abroad. He left his entire collection – about 1,500 works inherited from his father (including Picasso, Matisse, Chagall, Monet, Kokoschka, Courbet, Dürer, Canaletto, and others) worth an estimated billion dollars – to the Bern Art Museum, which is about to exhibit it in partnership with Bonn’s Bundeskunsthalle.
