About Margot Frank
Margot Betti Frank was the elder daughter of Otto Frank and Edith Frank and the elder sister of Anne Frank. Margot's deportation order from the Gestapo hastened the Frank family into hiding. According to the diary of her younger sister, Anne, Margot kept a diary of her own, but no trace of it has ever been found. She died in Bergen-Belsen concentration camp from a typhus outbreak. Although the first anti-Jewish measures soon took effect, Margot and her sister were not immediately affected. At first she shared a bedroom with Anne, but when Fritz Pfeffer moved in to the Secret Annex in November 1942, Margot slept in her parents' bedroom. They were later joined by four other Jewish refugees (Hermann, Auguste and Peter van Pels and Fritz Pfeffer) and remained hidden for two years until they were discovered on 4 August 1944. Despite initial problems with the Dutch language, Margot became a star pupil.
