Again, Jack, not what you said. You said this,
Maybe the concept of "journalist" didn't even exist exactly at that time.
You made no comment about "formalizing best practices." You said the "concept of journalist."
"Journalists" existed long before the first "J school" was established in America in 1908. They were called things like, "newspaper man," "town crier", and maybe even "the guy in the wagon that went from town to town selling stuff and spreading news one town to the next."
Expand your thinking, Jack.
And stop dancing so hard. It's okay to be wrong.
Your friend,
Bagster
Sort of like dentists of the period.
