Wait wait wait.
Having read many of the production memos I can tell you that one cannot safely assume that the line producer or writer of a given episode created all these things. Suggestions came from all over the place during rewrites; from Fontana, from Justman, and many from Roddenberry. In fact, a lot of the latter's memos are REALLY good, and he made many terrific points which improved the scripts and changed details. Coon did, too, to the scripts of others. How can someone claim Coon "created" Khan, when Carey Wilber's story included a superman (later to be renamed Khan)? To assign Coon all these "created bys" is as inaccurate as many of Roddenberry's later claims.
