Margaret St. Clair was an American fantasy and science fiction author active during the mid-twentieth century. Born in Hutchinson, Kansas, she later moved to California, where she earned a Master of Arts degree in Greek classics from the University of California, Berkeley in 1934. Alongside her husband, Eric St. Clair, she settled in Richmond and later El Sobrante, embarking on a professional writing career in the late 1940s.\n\nSt. Clair was highly prolific, publishing approximately 130 short stories and eight novels throughout her career. She frequently wrote under the pseudonyms Idris Seabright and Wilton Hazzard, with her work appearing in popular pulp magazines of the era such as Fantasy & Science Fiction and Startling Stories. Her writing often incorporated her interests in classical mythology, feminism, and early Wiccan beliefs, making her a distinctive and pioneering female voice in a male-dominated genre.\n\nAmong her most notable novels are Sign of the Labrys (1963), which is recognized for its early integration of Wiccan elements, and The Dolphins of Altair (1967), which explored ecological themes. St. Clair's contributions to science fiction and fantasy helped pave the way for future generations of women writers in speculative fiction.
