"Anne Frank and her family go into hiding

On this day in 1942 in Nazi-occupied Holland, 13-year-old Jewish diarist Anne Frank and her family were forced to take refuge in a secret sealed-off area of an Amsterdam warehouse. The day before, Anne's older sister, Margot, had received a call-up notice to be deported to a Nazi "work camp." Born in Germany on 12 June 1929, Anne Frank fled to Amsterdam with her family in 1933 to escape Nazi persecution.

In the summer of 1942, with the German occupation of Holland under way, 12-year-old Anne began a diary relating her everyday experiences, her relationship with her family and friends, and observations about the increasingly dangerous world around her. On 6 July, fearing deportation to a Nazi concentration camp, the Frank family took shelter in a factory run by Christian friends. During the next two years, under the threat of murder by the Nazi officers patrolling just outside the warehouse, Anne kept a diary that is marked by poignancy, humour, and insight."
