Myrna Lou Culbreath (born September 1, 1938)[1] is an American science fiction writer and editor, most well-known for the Star Trek tie-in novels and anthologies cowritten with Sondra Marshak.
[8] Sometime before 1977, Culbreath moved to Baton Rouge, Louisiana where she shared a home with her writing partner, Sondra Marshak.
[9][10] In the early-1970s, Culbreath began self-publishing an editorial newsletter under the title The Fire Bringer which focused on libertarian and objectivist issues.
In 1974, a special issue now known by the fanac title "The Star Trek Reprint" collected Culbreath's correspondence with Roddenberry.
"[4] During the mid-to-late 70's, Culbreath and her writing partner Sondra Marshak were regular guests of honor at science fiction conventions.
[11][12] After 1970, Culbreath made a number of attempts at writing a Star Trek episode spec script with Roddenberry's encouragement.
[13] In the author's notes for The Fate of the Phoenix (1979), Culbreath and Marshak announced a number of forthcoming titles: a fictional travel guide tentatively titled Mr. Spock's Guide to the Planet Vulcan, and a non-Star Trek science fiction novel with William Shatner, The Power, and new installments of The New Voyages series.
[14] Culbreath marketed a phonics-based reading method she claimed to have begun developing in the 1960s via seminars and tutoring events.
