This is Anne Frank in 1939. Three years later, for her 13th birthday, she receives a red-checked diary as a present. In three days, on June 12, this will be exactly 80 years ago. | Anne Frank House

Anne Frank and her family were arrested in August 1944 after 761 days in hiding in an annex above her father's business. The Holocaust demonstrated the worst of human cruelty as well as the extraordinary sacrifices of those willing to risk their lives to help others. Anne's experience illustrated both. While we know a great deal about those who helped the Franks survive in hiding, mystery surrounds their arrest. A retired FBI agent is trying to find the truth. | United States Holocaust Memorial
