Baroness Marie Blaze de Bury, née Marie Pauline Rose Stewart (or Stuart), was believed to be the illegitimate daughter of a British aristocrat. Beginning at age 18, she contributed to periodicals such as Revue des Deux Mondes, Revue de Paris, and Blackwood’s Magazine. In 1844, she married Baron Henri Blaze de Bury, a French diplomat and historian, and lived with him in Paris. There she hosted a salon that attracted writers, intellectuals, and politicians. She was fluent in French, English, and German, and promoted Anglo-European understanding, corresponding with the ambassadors of many nations. She wrote novels such Mildred Vernon (1849), All for Greed (1868), and Love the Avenger (1869). She traveled widely and wrote about her journeys in books such as Voyage en Autriche, Hongrie, Allemagne (1851). Some of her works were published under pseudonyms such as "Arthur Dudley" and "Maurice Flassan." One of her two daughters, Anne Emilie Rose Yetta Blaze de Bury, became a literary critic.
