A painting looted from a Berlin Jewish family by Nazis has been found by US authorities at the Kunsthaus museum in Zurich, museum officials said on Tuesday. Confirming a report by local media, the museum said that the painting was an 1887 portrait called Madame La Suire by Swiss painter Albert von Keller, who was popular in Berlin and Vienna at the beginning of the 20th century. The painting was acquired by the Sommerguths, a rich Jewish couple from Berlin who had a substantial collection of 106 paintings, including Renaissance masterpieces as well as works by Camille Pissaro.
