Hélène Berr
As the pages in her diary go by, Hélène's handwriting can get very hasty. Mariette Job, Hélène's niece, published and edited her diary. He was also a former bookseller. Once he began reading it, he realized that he was reading a text written by his niece (because of stuff circulating in her family, that she mentioned). The original copy of Hélène's diary was given to Jean Morawiecki, Hélène's fiance, and was in his hands, as she wished when she was still alive. He became a diplomat after the war ended. He also appointed Mariette Job as legatee of the diary.
