Anne Frank at her desk

In September 1942, only a few weeks after the Frank family went into hiding, Otto Frank and his thirteen-year-old daughter Anne began compiling Otto’s family tree. Over the following months, Anne became immersed in her family’s history based on the stories her parents told her. In May 1944 she recalled this experience in her diary. "Dearest Kitty, Have I ever told you anything about our family? I don’t think I have, so let me begin." Monday, 8 May 1944, Diary of Anne Frank
