Marion Eleanor Zimmer was born in Albany, NY, on June 3, 1930, and married Robert Alden Bradley in 1949. Mrs. Bradley received her B.A. in 1964 from Hardin Simmons University in Abilene, Texas, then did graduate work at the University of California, Berkeley, from 1965-67. She was a science fiction/fantasy fan from her middle teens. She had written as long as she could remember, but wrote only for school magazines and fanzines until 1952, when she sold her first professional short story to VORTEX SCIENCE FICTION. She wrote everything from science fiction to Gothics, but is probably best known for her Darkover novels and for her Arthurian novel, THE MISTS OF AVALON. In addition to her novels, Mrs. Bradley edited magazines, amateur and professional, including Marion Zimmer Bradley's FANTASY Magazine, which she started in 1988. She also edited an annual anthology called SWORD AND SORCERESS, which is still published annually under the title MARION ZIMMER BRADLEY'S SWORD AND SORCERESS. She died in Berkeley, California on September 25, 1999, four days after suffering a major heart attack.
