A fan and pro writer originally named Marion E. Zimmer, known for a time as Marion Breen and sometimes known as MZB. Her brother was Paul Edwin Zimmer. Originally from Albany, NY, she married Robert Bradley in 1949 and lived Rochester, Texas through the early 60s, divorcing him in 1964 and marrying Walter Breen (of later Breendoggle fame.) She finished college in 1965 and moved to the Bay Area for graduate school, finishing in 1967. Subsequently, she lived in New York and the Bay Area.
She published a number of fanzines such as Astra's Tower, Day*Star, Fantasy Ambler, Anduril, Gemini Fapa, On the Ragged Edge, and Anything Box and co-edited several other such as Ugly Bird with Redd Boggs, MEZRAB with her first husband Robert Bradley and Allerlei with her second husband Walter Breen. She edited Tightbeam in 1960. She ran for TAFF in 1963. She was a member of IPSO, FAPA (of which she was OE), and the Fellowship of the Ring.
In 1966, she helped found and named the Society for Creative Anachronism where she was known as "Elfrida of Greenwalls." She was involved in developing several local SCA groups, including in New York and was an editor of Pennoncel. In the 70s she lived in Greyhaven and she helped form the Vampire Society. She edited Banneret for the Aulic Council.
In 1961 she said of herself: "I am a member of Circus Fans of America, have other interests in Tolkien fandom, opera, folk songs, mountain climbing, and rock collecting."
Bradley and Breen separated in 1979 while remaining married, and continued a business relationship and lived on the same street. They divorced in 1990, after Breen was arrested on child molestation charges, though she later testified that she had been aware of his activities for many years.
Professionally, she is primarily known for the Darkover series. She made her first sale to Amazing Stories in 1949 with a story which had previously appeared in Spacewarp. She founded and sustained Marion Zimmer Bradley's Fantasy Magazine. She briefly published the Darkover Newsletter.
