Anne, not wanting to stifle her inner writer, believed the book would be best utilized as a journal. She wrote in two notebooks once the "diary" was filled, and finally on about 360 stray pieces of paper. One thing was certain: she enjoyed writing... Anne's father, Otto, was a lawyer who worked with Jewish refugees from Germany. He moved his family to Amsterdam so they could live among other people and escape the dangers of being a Jew in Nazi-occupied Europe. The Franks' apartment was sealed off by the police after Otto Frank was arrested at the end of July 1942. He was sent to Auschwitz where he died. The rest of the family were sent to concentration camps where they also perished. Only Anne, her sister Margot, and another girl survived. She spent several years living in hiding before the secret annex was found by the Germans looking for documents pertaining to Jews. They allowed the girls to stay and even gave them jobs but eventually they were sent to the Westerbork transit camp where they would board trains for Switzerland or Brazil. However, the Swiss government refused to accept them so they stayed in the Netherlands until the war ended in 1945. After the liberation of the Netherlands, Otto's wife Mina decided that it would be best if they didn't return home because their house had been converted into a hospital for war victims.
