Anne Frank House is one of the most visited Holocaust museums worldwide, dedicated to Anne Frank and her wartime diaries. Who was Anne Frank? The now-famous Jewish diarist was just 13 when she went into hiding from Nazi Germany's occupation of Amsterdam. Her father, Otto, furnished a secret annexe in his business building. Anne, an aspiring writer, spent much of her two years in hiding, writing in her diary. She shared stories about day-to-day life, thoughts and feelings about life in the hidden annexe. The secret annexe was discovered in 1944. Its occupants, including Anne, Otto and their family, were transported to concentration camps and separated. Anne died from exhaustion and typhus in the Bergen-Belsen concentration camp in 1945. Her father, Otto, was the only person from the hidden annexe to survive the Nazi camps; he was liberated by the Russians and returned to the Netherlands in 1945. Otto learned that Anne had intended to publish her diaries and eventually did so in her memory. Since then, the book has been translated into more than 70 languages. The annexe has become a part of Anne Frank House, one of the most famous museums in Amsterdam today. Otto was heavily involved in the opening of Anne Frank House, where visitors can see pages from the original diary and objects from the family's two-year stay in the annexe.
