Elizabeth von Arnim (1866–1941) (pseudonym of Mary Annette Beauchamp) married German nobleman Count Henning August von Arnim (1851–1910) in 1891. Apparently he was domineering and abusive and her second marriage to John Francis Stanley Russell not much better. Although she never wrote an autobiography, Arnim created her pseudonym and started writing her Elizabeth series, which contain many details of her own life. A remarkable writer, I wonder if she would have bothered if she'd not been unhappily married?
