When the Germans invaded the Netherlands and Heinz received a call-up to a work-camp, the family went into hiding. They successfully hid for two years and might have survived the war if they had not been betrayed in May 1944. They were then captured by the Nazis and sent to Auschwitz-Birkenau concentration camp.[1] They were liberated in January 1945 by the Soviets, but Erich and Heinz Geiringer had perished in the forced march to Mauthausen that came just before the war ended. Geiringer and her daughter Eva returned to Amsterdam on 13 June 1945. Otto Frank visited them at their apartment not long after.[citation needed]
