Not my intent to slight the others involved.
It's just that was the first thought that struck way back when I first read that document. In fact it is Justman, IIRC, that deserves credit for the presence of Worf in TNG, for example. I'm sure there are other aspects of the series that can be traced back to any one of those folks individually and/or in combination.
Please forgive if I be retracing steps already laid, but isn't this also a bit of history repeating itself as in Gene Roddenberry having a clear and definite m.o.?
I say this in terms of many elements fandom found to be endearing trademark features of TOS were contributed by a various folks (not the least of which being Gene Coon).
