In the Star Trek episode "Whom Gods Destroy" (1969), I consider the character Garth a George Washington figure (whether consciously intended or not). He was a great military leader; also, his "consort" is named Marta (compare Martha).
There's There's also a resemblance, both physically and in body language.
(The narrative may also have been inspired by Douglas MacArthur, in that Garth has lost his mind, wanting to be addressed as "Lord Garth.") Steve Ihnat as Captain Garth:
It's possible other Starfleet captains evoke figures from U.S. history. (Of course, James Kirk has been compared to JFK.)
Specifically
Specifically, I'm asking about Captain Ronald Tracey of "The Omega Glory" (1968). He too has gone power-mad, on a planet he believes holds the secret to immortality. He breaks the Prime Directive by taking sides in war between the "Yangs" and the "Kohms," or Yankees vs. Communists. (It's probably not relevant to the question, but neither of these is considered a good episode.) Below, Morgan Woodward as Capt. Tracey:
Again, I'm mainly asking about physical resemblance, with plot being secondary. Does Captain Tracey resemble any particular famous American (pre-1969)?
Also secondary: the conscious intent of the filmmakers. As a longtime fan, I don't remember anything particularly interesting, in interviews, regarding "The Omega Glory" (Gene Roddenberry is the credited writer). Note: I haven't yet read These Are the Voyages by Cushman, which seems to be an important reference.
I realize the two characters pictured resemble each other, to some degree, but there seems enough difference to ask the question. Also, Tracey doesn't seem Washington-like: whereas Garth strikes patrician poses, Tracey is more gritty and intense. He also retains his skills, with his fall-from-grace being solely due to choices.
