When the Americans approached the Buchenwald concentration camp, the SS left on 11 April 1945. The Dutch painter Han Pieck was imprisoned in Buchenwald since 1941 as a communist. Before the war Pieck had worked for the Soviet-Russian secret service (the GPU). His twin brother Anton Pieck led a quiet life as a teacher and drawer of nostalgic scenes. Anton found the artistic talent of his brother Han superior to his own.
