British Socialite, Author, and Nazi Sympathizer. A daughter of David Freeman-Mitford, 2nd Baron Redesdale, she was one of the storied Mitford sisters and considered a great beauty. Diana Mitford belonged to a social group labelled by journalists as "the Bright Young Things," a group of young aristocrats prominently followed by the press in 1920s London. She was largely educated at home, as was customary for young women of her station and generation, and presented at court at the age of eighteen. She was married on January 30, 1929 to Bryan Walter Guinness, the future 2nd Baron Moyne, the eldest son and heir of Walter Guinness, 1st Baron Moyne, an heir of the Guinness brewing fortune. The marriage was initially happy, but she would eventually leave Guinness for Sir Oswald Mosley, 6th Baronet, becoming his mistress. Mosley was a British politician, the founder and leader of the British Union of Fascists (BUF). Influenced by Mosley, she became attracted to Fascist ideology and traveled to Germany in 1934 with her younger sister, Unity, where she attended her first Nuremberg Nazi Party rally. She became personal friends with Adolf Hitler and many high-ranking Nazi Party members including Joseph and Magda Goebbels. It was at their house, on October 6, 1936, that she and Mosley were married, with Hitler as their guest of honor. They were to have two sons. She and her husband were arrested in 1940 and interned for much of World War II as Fascist sympathizers under the authority of Regulation 18B of the Defense (General) Regulations 1939, allowing for the internment without trial of people suspected of being actively opposed to Britain's war with Germany. Initially held separately, she and Mosley were eventually permitted to be together at the Holloway Prison. They were released from Holloway Prison in 1943 and confined to house arrest, not being released until the end of the war. Following the war, the Mosleys were ostracized by some elements of society and shunned by the media, but this did not significantly hinder their social life and they were known for entertaining. They initially lived in Ireland and from 1950 resided in France, where they were neighbors and became close friends of the Duke and Duchess of Windsor. The Mosleys established their own publishing company, Euphorion Books, owing to the hesitance of publishers to work with them because of their past political associations. She translated several classic pieces of literature; edited several of her husband's books; edited the controversial magazine, "The European"; and authored an autobiography. She wrote a column, "Letters from Paris," for the magazine, "Tatler," beginning in 1965 and wrote regularly for Books and Bookmen, specializing as a reviewer of autobiographies and biographies. A collection of her articles, diaries, and book reviews were published posthumously in 2008, entitled "The Pursuit of Laughter." She was forced to move in 1998 from what had been her home since 1950, the Temple de la Gloire, in Orsay, southwest of Paris, due to her age, moving into an apartment in the 7th arrondissement of Paris. Her death at the age of 93 is attributed to the European heat wave of 2003. Diana Mosley never repudiated her belief in Fascism and support of the Nazi regime in Germany
