Annelies Marie "Anne" Frank was born on 12 June 1929 in Frankfurt, Germany, the second daughter of Otto Frank (1889–1980) and Edith Frank-Holländer (1900–45). Margot Frank (1926–45) was her elder sister. The Franks were liberal Jews and lived in an assimilated community of Jewish and non-Jewish citizens, where the children grew up with Catholic, Protestant, and Jewish friends. The Frank family did not observe all of the customs and traditions of Judaism. Edith Frank was the more devout parent, while Otto Frank, a decorated German officer from World War I, was interested in scholarly pursuits and had an extensive library; both parents encouraged the children to read.
