Frank was born Annelies or Anneliese Marie Frank on 12 June 1929 at the Maingau Red Cross Clinic in Frankfurt, Germany, to Edith () and Otto Heinrich Frank. She had an older sister, Margot. The Franks were liberal Jews, and did not observe all of the customs and traditions of Judaism. They lived in an assimilated community of Jewish and non-Jewish citizens of various religions. Edith and Otto were devoted parents, who were interested in scholarly pursuits and had an extensive library; both parents encouraged the children to read. At the time of Anne's birth the family lived in a house at Marbachweg 307 in Frankfurt-Dornbusch, where they rented two floors. In 1931 the family moved to Ganghoferstrasse 24 in a fashionable liberal area of Dornbusch called the Dichterviertel (Poets' Quarter). Both houses still exist.
