Anne Frank became known for her diary, The Diary of Ann Frank, which recounts the two years she spent hiding with her family during World War II, from 1942 to 1944. As Jews living in the Nazi-occupied Netherlands, the Franks were forced to go into hiding in the building where Anne’s father worked. Anne and her family were later arrested by the Gestapo (the German secret police) and sent to concentration camps, which only Anne’s father survived. In its powerful account of persecution and injustice, as well as in its embrace of hope, Anne’s diary has a powerful impact on Ms. Gruwell’s students, making them acutely aware of the horrors of the Holocaust and ethnic hatred in general.
