Deep Space Nine is her favorite Star Trek spinoff. She especially liked the show’s strong characters. When writing, Fontana has used pseudonyms, including Michael Richards and J. Michael Bingham.
Fontana worked as a writer for a few television series before Star Trek, then briefly worked as Gene Roddenberry’s secretary, before she became a writer on the show. The first episode she penned was “Charlie X”, based on a premise by Roddenberry entitled “The Day Charlie Became God”. Fontana wrote several notable Original Series episodes, including “Tomorrow is Yesterday” and “Journey to Babel”. Also, after the departure of Steven W. Carabatsos, she was promoted to story editor (after successfully re-writing “This Side of Paradise”). At the age of 27, Fontana became the youngest story editor in Hollywood at the time, and also one of the few female staff writers.
