D.C. Fontana, a writer and story editor for the original Star Trek television series and later a contributor to Star Trek: The Next Generation and other related projects, has died at age 80.

A statement on the Star Trek website said she died Monday after a brief illness.

Dorothy Catherine Fontana, who used the initials D.C. after struggling to find work in a male-dominated industry, had befriended Star Trek creator Gene Roddenberry and rose from secretary to story editor for the 1960s show.

Her credits included such episodes as Journey to Babel and Friday’s Child, and Leonard Nimoy would praise her for broadening the back story of Mr. Spock’s Vulcan culture.

William Shatner, who starred as Capt. James T. Kirk, tweeted that Fontana was a “pioneer” and added that “her work will continue to influence for generations to come.”

A native of Sussex, New Jersey, Fontana worked on a wide range of other TV shows, including Bonanza and Ben Casey, along with Star Trek: The Next Generation and the web series Star Trek: New Voyages

She also wrote the Star Trek novel Vulcan’s Glory, about Spock’s first mission on the USS Enterprise.
