British socialite, fascist, and author Diana Mosley (née Mitford) was the daughter of David Freeman-Mitford, 2nd Baron Redesdale, and part of the aristocratic Mitford family of England. Known for her grace and beauty, she was initially married to Bryan Walter Guinness, with whom she had two sons. She later started an affair with the much-married Sir Oswald Mosley, 6th Baronet and got married to him after the death of his first wife. She later had two sons with Oswald too and supported his activities as part of the British Union of Fascists. She also visited Nazi Germany frequently with her sister Unity and became part of Adolf Hitler’s inner circle. Diana and Oswald were later imprisoned at Holloway Prison. Following their release, they stayed in Ireland and then in Paris, trying to re-build their social and political lives. She died due to the 2003 heatwave in Paris, at age 93.
