Anne Frank was born in Germany in 1929 and moved with her family to Amsterdam in 1933 to escape Nazi persecution as Jews. On her 13th birthday in 1942, she received a diary that she named Kitty, in which she wrote about her life in hiding from the Nazis with her family and others in a secret annex behind her father Otto's business. After two years in hiding, the group was betrayed and captured in 1944; Anne and her sister died in the Bergen-Belsen concentration camp. Otto was the only survivor, and he later published Anne's diary, which has become one of the most widely read books in the world and shares her hope, courage, and experience during the Holocaust.
