Anne Frank -  The author of the diary. Anne was born on June 12,1929, in Frankfurt, Germany, and was four years old when her father moved to Holland to find a better place for the family to live. She is very intelligent and perceptive, and she wants to become a writer. Anne grows from an innocent, tempestuous, precocious, and somewhat petty teenage girl to an empathetic and sensitive thinker at age fifteen. Anne dies of typhus in the concentration camp at Bergen-Belsen in late February or early March of 1945.

Margot Frank -  Anne’s older sister. Margot was born in Frankfurt in1926. She receives little attention in Anne’s diary, and Anne does not provide a real sense of Margot’s character. Anne thinks that Margot is pretty, smart, emotional, and everyone’s favorite. However, Anne and Margot do not form a close bond, and Margot mainly appears in the diary when she is the cause of jealousy or anger. She dies of typhus in the concentration camp a few days before Anne does.

Otto Frank  -  Anne’s father. Otto is practical and kind, and Anne feels a particular kinship to him. He was born on May 121889, into a wealthy Frankfurt family, but the family’s international-banking business collapsed during the German economic depression that followed World War I. After the Nazis came to power in Germany, Otto moved to Amsterdam in 1933 to protect his family from persecution. There he made a living selling chemical products and provisions until the family was forced into hiding in 1942. Otto is the only member of the family to survive the war, and he lives until 1980.
