The original “Star Trek” premiered in 1966 and ran until 1969. The show’s final year featured an episode written by Lewis and her husband, titled “The Lights of Zetar.” The episode first premiered on January 31, 1969 (per IMDb, which also gives series creator Gene Roddenberry a co-writing credit).
So how did this future popular puppeteer come to write an episode for the show? Lewis was married twice. Her second marriage was to Jeremy Tarcher, who was also a writer and worked in production. The pair wed in 1958 and nearly a decade after their nuptials, the couple wrote an episode for the iconic show together. It was the only chapter of the “Star Trek” show they were both credited with writing. According to their daughter, Mallory Tarcher, Lewis apparently wrote a role for herself when she submitted it, but lost out to someone closer to the big producers, per Country Living. She also categorizes the episode her parents wrote as “arguably one of the most boring episodes ever.”
