Anne Frank's major accomplishment was writing her diary, which she kept for more than two years while she and her family were hiding from the Nazis during World War II. The family was eventually discovered and taken to concentration camps, and the diary was found after the family was deported. Her diary endures as a testament to the human spirit.
Anne received the diary on her 13th birthday, just a few weeks before her family went into hiding. Both Anne and her sister Margot, who was four years her senior, kept diaries documenting their experiences while in hiding, but Margot's diary was never found. In her diary, Anne described what it was like to live in constant fear of being discovered. The family had to keep quiet at all times, and they had to conceal all lights and keep curtains and windows closed after sunset. They were completely dependent on others for basic necessities. Anne also wrote many of her thoughts and feelings about life, sexuality and her experience of transforming from a little girl into a young woman.
Anne and her family were eventually betrayed by someone who knew they were in hiding, and they were taken to a concentration camp and forced to perform hard labor. Anne and her sister were later transferred to the Bergen-Belsen concentration camp in Germany, where they both contracted typhus, a bacterial disease. Anne and her sister died within days of each other; Anne was just 15 years old when she died. Anne's mother also fell ill and died. Anne's father, Otto, was the only member of the immediate family to survive.
