Felix Nussbaum was born in Osnabrueck, Germany, and studied in Hamburg, Berlin and Rome. He and his companion, Felka Platek, settled in Belgium in 1935. In 1940, he was arrested with all other aliens and sent to the camps of Saint Cyprien and Gurs in southern France. Nussbaum managed to escape, and lived in hiding in Brussels until he was caught in 1944 and sent to Auschwitz, where he perished (Wikipedia).
Denna underbara målning heter "Einsamkeit" och fanns att beskåda i Berlin. Vad museét hette kommer jag ej ihåg.
