D.C. Fontana, who helped craft the lore of the 1960s television series “Star Trek” and developed one of its signature characters, Spock, as the show’s first female writer, died on Tuesday at a hospital in Burbank, Calif. She was 80.
Her husband and only immediate survivor, Dennis Skotak, said the cause was cancer. Ms. Fontana was part of the “Star Trek" universe from its early days, working alongside the show’s creator, Gene Roddenberry, as a story editor and writer.
