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. In 1933, after Adolf Hitler's Nazi Party won the federal election and Hitler was appointed Chancellor of the Reich, Edith Frank and the children went to stay with Edith's mother Rosa in Aachen. Otto Frank remained in Frankfurt, but after receiving an offer to start a company in Amsterdam, he moved there to organize the business and to arrange accommodations for his family. He began working at the Opekta Works, a company that sold the fruit extract pectin.

In November 1933, Edith followed her husband and a month later Margot moved to Amsterdam. Anne stayed with her grandmother until February, when the family reunited in Amsterdam. The Franks were among 300,000 Jews who fled Germany between 1933 and 1939. After moving to Amsterdam, Anne and Margot Frank were enrolled in school—Margot in public school and Anne in the 6th Montessori School. Despite initial problems with the Dutch language, Margot became a star pupil in Amsterdam. Anne soon felt at home at the Montessori school and met children of her own age, like Hanneli Goslar, who would later become one of her best friends. In 1938, Otto Frank started a second company, Pectacon, which was a wholesaler of herbs, pickling salts, and mixed spices, used in the production of sausages. Hermann van Pels was employed by Pectacon as an advisor about spices. A Jewish butcher, he had fled Osnabrück with his family. In 1939, Edith Frank's mother came to
