Margaret St. Clair (b. 1911, d. 1995) was an US science fiction writer, who also wrote under the pseudonym Idris Seabright. She started writing science fiction with the short story Rocket to Limbo in 1946. Her most creative period was during the fifties, when she wrote such classic stories as The Man Who Sold Rope to the Gnoles (1951), Brightness Falls from the Air (1951), An Egg a Month from All Over (1952) and Horrer Howce (1956). She largely stopped writing short stories after 1960.

Apart from more than 100 short stories, Margaret St. Clair also wrote eight novels; her short fiction is collected in several collections, the most recent of which is The Best of Margaret St. Clair (1985), which makes for a good sampler of her work.

Of interest beyond science fiction is her 1963 novel Signs of the Labrys, for its early use of Wicca elements in fiction. For more on this see this review (http://www.chasclifton.com/columns/column17.html) (External link).
