Miriam’s parents were enlightened people with leftist opinions. They were business people in Érsekújvár (Nové Zámky). In 1938, after the Hungarian invasion, Miriam joined the “Hashomer Hatzair” movement with the encouragement of her mother who took part in some of the activities. The adult members of the movement founded the Sela Organization within whose framework Miriam went on an agricultural hahshara. In 1942 she moved to Budapest where she met her future husband, Amram Grünwald (Amir). Miriam helped with the absorption of Jewish refugees arriving from Slovakia. After the Germans invaded Hungary on 19.3.1944, she engaged in obtaining authentic documents from the Population Registry offices and modifying them for those who needed them. She helped refugees from Poland from whom she heard about the extermination of Jews. Miriam sent forged documents to her parents but they were afraid of escaping from the ghetto. Together with Amram, who had run away from service in a forced labor unit, and with the help of comrades from the movement, especially Moshe Pil (Alpan), she arrived in Nagyvárad (Oradea) and crossed the border into Romania. Miriam made aliya and joined Kibbutz Ein Dor.
