Anne Frank (12 June 1929 — February 1945) was a German-born Jewish girl who, along with her family and four other people, hid in the second and third floor rooms at the back of her father's Amsterdam company during the Nazi occupation of the Netherlands. Helped by several trusted employees of the company, the group of eight survived in the achterhuis (literally "back-house", usually translated as "secret annex") for more than two years before they were betrayed, and arrested. Anne kept a diary from 12 June 1942 until 1 August 1944, three days before the residents of the annex were arrested. Anne mentioned several times in her writings that her sister Margot Frank also kept a diary, but no trace of Margot's diary was ever found. After spending time in both Westerbork and Auschwitz, Anne and her elder sister Margot were eventually transported to Bergen-Belsen, which was swept by a massive typhus epidemic that began in the camp in January 1945. The two sisters died, evidently a few days apart, sometime in February 1945. Both were buried in one of the mass graves at Belsen, though it is unknown to this day exactly which of the many mass graves at Belsen contains their remains. Their "tombstone" that can be viewed at Belsen today is merely a memorial to the two sisters, and does not mark their actual burial site. Their father, Otto Frank, survived the war and upon his return to Amsterdam was given the diary his daughter had kept during their period of confinement, which had been rescued from the ransacked achterhuis by Miep Gies (below) who, out of respect for Anne's privacy, had not read it. The diary was first published in 1947, and by virtue of worldwide sales since then, it has become one of the most widely read books in history. It is recognized both for its historical value as a document of the Holocaust and for the high quality of writing displayed by such a young author. In 2010, Anne was honored as one of the most iconic women of the year. She is also one of the most well known victims of the Holocaust. Her friend Eva Schloss, who survived the Holocaust, became her stepsister after Anne Frank's death. The other occupants of the Secret Annex Otto Frank (12 May 1889 – 19 August 1980; Anne and Margot's father, husband of Edith) was in
