In 1927, she married the shipowner Knud Lauritzen [da] with whom she had six children: Grete (1930), Ole (1933), Lise (1936), Marianne (1939), Karen (1942) and Jan (1943).
[1] Raised in a well-to-do home by parents who were socially active, especially in their commitment to education and the well-being of children, she was the first girl to attend Gammel Hellerup Gymnasium where her father was the principal.
[1] Under the German occupation of Denmark (1939–1945), Lauritzen was active in the Danish Women's Society Service (Danske Kvinders Samfundstjeneste or DKS) under the Women's Council in Denmark, chairing the Copenhagen branch of DKS and organizing the production of large quantities of jam from wild fruit for those in financial difficulties.
[2] After the liberation in 1945, she headed a fund-raising campaign to help German children orphaned by the war, criticizing the Danish Women's Society for refusing support.
At the large Storedam residence in Tokkekøb Hegn which she inherited from her father in 1953, she provided accommodation for refugees from Hungary in 1956 and for those from the Vietnam war in 1975.
