Dorothy Fontana has Died

I've just heard that DC Fontana, one of the best writers for Classic Star Trek, and someone who invented almost everything we know about Vulcans, has died. She was 80.
She was the story editor for the original series, after her work on the episodes Charlie X and This Side of Paradise. Other episodes she was responsible for are Tomorrow is Yesterday, Friday's Child, and the wonderful Journey to Babel.
In the third season, as a freelance writer, she wrote The Enterprise Incident, That Which Survives and The Way to Eden (oh, well - the space hippies one was not her finest hour....).
Later she wrote the animated episode Yesteryear, where we finally see Spock's sehlat.
She also worked with Gene Roddenberry on The Questor Tapes and Genesis II (Questor was kind of an early version of Data).
Later she worked on other SF shows, including the original Battlestar Galactica - The Gun on Ice Planet Zero was one of hers, which I remember fondly. It was sort of Guns of Navarone in space. She also worked on Encounter at Farpoint, the pilot episode of Star Trek TNG, and on Babylon 5. She also wrote the Star Trek novel Vulcan's Glory, which I remember snapping up as soon as I saw the author's name.
She attended one of the Star Trek conventions in the 1980s that I went to - I remember being very shy but going up to get her autograph anyway. One of the other guests at that convention was a stuntman friend of Gene Roddenberry's, who had worked on the Errol Flynn film Robin Hood!
She was one of my inspirations when I wanted to become a writer - I've never got any further than self-publishing and blogging, but I know where to look when I want to find out how to write a scene, and how to write three dimensional characters!
