Helen Azar is a public librarian specializing in history. She grew up in a Russian speaking household and as a child used to translate paragraphs from children's books and magazines for fun. Helen's professional scientific training and a passion for Russian history led to co-authoring several articles on the identification of the remains of the last Tsar and his family. While researching for her first book, The Diary of Olga Romanov: Royal Witness to the Russian Revolution, Helen visited Russia several times, and as part of academic curriculum worked in the Rare Book Fund at the Museum at Tsarskoe Selo, which holds the imperial book collection, including that of Catherine the Great and the last Tsar Nicholas II.
