Marion Eleanor Zimmer Bradley (1930 - 1999) was an American author of fantasy, historical fantasy, science fiction, and science fantasy novels, and is best known for the Arthurian fiction novel The Mists of Avalon, and the Darkover series. While some critics have noted a feminist perspective in her writing, her popularity has been posthumously marred by multiple accusations against her of child sexual abuse and rape by two of her children, Mark and Moira Greyland, among many others. Zimmer Bradley's first child, David R. Bradley, and her brother, Paul Edwin Zimmer, also became published science fiction and fantasy authors.
