Nora’s mother Ilona Kronstein (née Neumann), was born in Budapest in 1897 to Sigmund and Emma (née Deutsch) Neumann. In 1918, she met Robert Kronstein. The couple married a year later and moved to Vienna. In 1939, she moved to a small town near Nice, France and solely devoted herself to art. While Ilona tried many different art forms, she predominantly produced drawings. It was in Nice that she became friends with the painter Rudolf Ray Rapaport. In 1940 she was detained in the concentration camp at Gurs for several weeks. From 1941 onwards she began to show signs of multiple sclerosis. Her family managed with great difficulty to get her back to Liechtenstein in 1942 and to obtain medical assistance for her in Switzerland. She died in Zurich in 1948.
