While David Gerrold canonised the “T” as standing for “Tiberius” in “Bem”, we did know that his middle name started with the letter “T” as far back as “Mudd’s Women” IIRC. You undoubtedly already knew this
I actually was not aware of that! Interesting that “Where No Man Has Gone Before” and “Mudd’s Women” had different middle initials for Kirk considering the later was originally conceived as possible second pilot as well. Too bad “The Omega Glory” didn’t also get in on the game.
