SNW S2 EP3 piqued my curiosity in who this character was based off of and so I did a very basic search. I already knew Roddenberry named Khan and Dr. Noonian Soong that way to try to get the attention of his friend, but seems like the friend never noticed and reached out.
My current search yielded a VERY comprehensive post on R3dd!t from 2020 where the OOP and commenters came up with some possible iterations:
Kim Noonien Singh Kim Noonien Wang Kim Ngyuen Singh Kim Noonan Singh
Unfortunately, the trail seems to have run cold as the OOP has not updated on any new leads and the last comment in that thread is a year ago.
Do you think we are ever going to be able to find out who the real life “Khan Noonien Singh” is/was?
I guess we should take a step back, then to determine whether this as a person existed. If the person as an individual didn’t, then perhaps it was a group of buddies named Kim, Nyguen, and Singh. Probably a stretch, though.
I’m just wondering if there are no photographs or any other of Roddenberry’s war buddies can corroborated this guy’s existence. Should he also not have shared wartime stories with his children and wife? AFAIK, they haven’t shared any information but it’s also possible that no one had asked them.
