 Passage 3:Samuel-Cahn was born in Oslo, Norway. During the Nazi occupation of Norway, in 1942, her father, a rabbi, was warned that he would be arrested by the Germans. He refused to leave in order to try to support his community. In September, her father was ordered to report to the Gestapo office, where he was questioned and later sent to Auschwitz. Later that year, the Nazis were going to arrest the other Jews in Oslo, however Samuel-Cahn's family were moved by members of the underground, Ingebjørg Sletten-Fosstvedt and Sigrid Helliesen Lund, to safety and later to a refugee camp in neutral Sweden. In order to cross the border, Samuel-Cahn and the rest of her family had to hide in trucks used to transport potatoes. In Stockholm, Samuel-Cahn's family found out that her father had been killed in Auschwitz. In 1946, Samuel-Cahn, her mother and brothers moved to Mandatory Palestine (part of which later became Israel).
