Fears looted Nazi art still hanging in Belgian and British galleries

Leading art museums are reassessing their works after a Belgian journalist traced how a fascist sympathiser acquired a Jewish dealer's collection

In August 1940, Samuel Hartveld and his wife, Clara Meiboom, boarded the SS Exeter ocean liner in Lisbon, bound for New York. Aged 62, Hartveld, a successful Jewish art dealer, left a world behind. The couple had fled their home city of Antwerp not long before the Nazi invasion of Belgium in May 1940, parting with their 23-year-old son, Adelin, who had decided to join the resistance.

Hartveld also said goodbye to a flourishing gallery in a fine art deco building in the Flemish capital, a rich library and more than 60 paintings. The couple survived the war, but Adelin was killed in January 1942. Hartveld was never reunited with his paintings, which were snapped up at a bargain-basement price by a Nazi sympathiser and today are scattered throughout galleries in north-western Europe, including Tate Britain.
