In 1942, Anne Frank received a diary for her 13th birthday. While hiding for two years in secret rooms in an office building, Anne recorded her personal thoughts, and this Diary of Anne Frank has become the most widely-read account of life during the Holocaust. Anne's family had moved from Germany to Amsterdam after Hitler gained power, but were trapped when the Nazi occupation extended into The Netherlands in 1942. After two years in hiding, the group was betrayed and transported to concentration camps where Anne died of typhus in Bergen-Belsen. It is estimated that of the 110,000 Jews deported from the Netherlands during the Nazi occupation, only 5,000 survived. Anne's father, Otto, survived and returned to Amsterdam after the war, where he relocated Anne's diary and had it published. After Simon Wiesenthal was challenged by Holocaust deniers that Anne Frank never existed, he proved her existence five years later by finding the Nazi officer who had arrested her. Today, the building in Amsterdam where she hid, the Anne Frank House, is a museum visited by nearly one million people each year. Time magazine selected Anne Frank as one of 100 most influential people of the 20th Century.
