The bestselling book Anne Frank: Diary of a Young Girl brought to life one of the greatest horrors of the 20th century in a compelling, personal way. In the true story, a young Jewish girl, her family, and some friends are forced into hiding in Amsterdam to escape the Nazis during World War II. The house that served as the Frank family’s hiding place for two years survived the war and is now a moving museum, with the primary site being the achterhuis (rear house), also known as the secret annex. Here the Franks sat in silence during the day and ate food that was secretly brought to them, before being mysteriously betrayed and sent to Nazi concentration camps. Otto Frank, the only Frank who survived the war, published Anne’s now-famous diary in 1947.
