Marion Eleanor Zimmer Bradley was an American author of fantasy novels such as The Mists of Avalon and the Darkover series, often with a feminist outlook. Bradley's first published novel-length work was Falcons of Narabedla, first published in the May 1957 issue of Other Worlds. When she was a child, Bradley stated that she enjoyed reading adventure fantasy authors such as Henry Kuttner, Edmond Hamilton, and Leigh Brackett, especially when they wrote about "the glint of strange suns on worlds that never were and never would be." Her first novel and much of her subsequent work show their influence strongly. Early in her career, writing as Morgan Ives, Miriam Gardner, John Dexter, and Lee Chapman, Marion Zimmer Bradley produced several works outside the speculative fiction genre, including some gay and lesbian pulp fiction novels. For example, I Am a Lesbian was published in 1962. Though relatively tame by today's standards, they were considered pornographic when published, and for a long time she refused to disclose the titles she wrote under these pseudonyms. Her 1958 story The Planet Savers introduced the planet of Darkover, which became the setting of a popular series by Bradley and other authors. The Darkover milieu may be considered as either fantasy with science fiction overtones or as science fiction with fantasy overtones, as Darkover is a lost earth colony where psi powers developed to an unusual degree. Bradley wrote many Darkover novels by herself, but in her later years collaborated with other authors for publication; her literary collaborators have continued the series since her death. Bradley took an active role in science-fiction and fantasy fandom, promoting interaction with professional authors and publishers and making several important contributions to the subculture. For many years, Bradley actively encouraged Darkover fan fiction and reprinted some of it in commercial Darkover anthologies, continuing to encourage submissions from unpublished authors, but this ended after a dispute with a fan over an unpublished Darkover novel of Bradley's that had similarities to some of the fan's stories. As a result, the novel remained unpublished, and Bradley demanded the cessation of all Darkover fan fiction. Bradley was also the editor of the long-running Sword and Sorceress anthology series, which encouraged submissions of fantasy stories featuring original and non-traditional heroines from young and upcoming authors. Although she particularly encouraged young female authors, she was not averse to including male authors in her anthologies. Mercedes Lackey was just one of many authors who first appeared in the anthologies. She also maintained a large family of writers at her home in Berkeley. Ms Bradley was editing the final Sword and Sorceress manuscript up until the week of her death in September of 1999. Probably her most famous single novel is The Mists of Avalon. A retelling of the Camelot legend from the point of view of Morgaine and Gwenhwyfar, it grew into a series of books; like the Darkover series, the later novels are written with or by other authors and have continued to appear after Bradley's death. Her reputation has been posthumously marred by multiple accusations of child sexual abuse by her daughter Moira Greyland, and for allegedly assisting her second husband, convicted child abuser Walter Breen, in sexually abusing multiple unrelated children.

Alice Mary Norton always had an affinity to the humanities. She started writing in her teens, inspired by a charismatic high school teacher. First contacts with the publishing world led her, as many other contemporary female writers targeting a male-dominated market, to choose a literary pseudonym. In 1934 she legally changed her name to Andre Alice. She also used the names Andrew North and Allen Weston as pseudonyms. Andre Norton published her first novel in 1934, and was the first woman to receive the Gandalf Grand Master Award from the World Science Fiction Society in 1977, and won the Damon Knight Memorial Grand Master Award from the Science Fiction and Fantasy Writers of America (SFWA) association in 1983. Norton was twice nominated for the Hugo Award, in 1964 for the novel Witch World and in 1967 for the novelette "Wizard's World." She was nominated three times for the World Fantasy Award for lifetime achievement, winning the award in 1998. Norton won a number of other genre awards, and regularly had works appear in the Locus annual "best of year" polls. On February 20, 2005, the Science Fiction and Fantasy Writers of America, which had earlier honored her with its Grand Master Award in 1983, announced the creation of the Andre Norton Award, to be given each year for an outstanding work of fantasy or science fiction for the young adult literature market, beginning in 2006. Often called the Grande Dame of Science Fiction and Fantasy by biographers such as J. M. Cornwell and organizations such as Science Fiction and Fantasy Writers of America, Publishers Weekly, and Time, Andre Norton wrote novels for over 70 years. She had a profound influence on the entire genre, having over 300 published titles read by at least four generations of science fiction and fantasy readers and writers. Notable authors who cite her influence include Greg Bear, Lois McMaster Bujold, C. J. Cherryh, Cecilia Dart-Thornton, Tanya Huff, Mercedes Lackey, Charles de Lint, Joan D. Vinge, David Weber, K. D. Wentworth, and Catherine Asaro.
