Just from the limited amount of info on the "TNG" bonus material, I always thought Mrs. Fontana was a short-lived writer for that show, who was fired for disagreeing with Gene Roddenberry. But I looked her up anyway, and it turned out she wrote ten episode of "TOS", five of "TNG", and one each of "TAS", "DS9", and "New Voyages". She also wrote one novel for Pocket Books, called "Vulcan's Glory", and an IDW comic book titled "The
Enterprise Experiment". She also wrote the scripts for Bethesda Softworks video games "Star Trek: Legacy" and "Star Trek: Tactical Assault". Todd Vaughn, the company's VP of Development, described Mrs. Fontana as "one of Star Trek's most prolific and distinguished writers".
Sadly, she passed away in 2019, from cancer.
