I support Whit's take on the silliness of the question.
The world that Vernon was born into and grew up in, the magicians that he was exposed to and with whom he associated and watched in vaudeville no longer exists. It was gone before World War II.
In one of Christopher's history books he mentions that there were 4,000 magicians who worked vaudeville over its history. I presume that both Europe and English music halls had thousands as well, most of whom we will never know much about. That means a lot of working professionals saw and influenced each other in large and small ways. There was a different synergy back then.
That and amateur magic had a small population with books and apparatus being expensive and hard to get. The dissemination of magic knowledge was limited and slow to spread, unlike today where it proliferates, often at the speed of light. Today amateur magic has a different demographic and was not coming of age as it was in the 1920s, 30s, and 40s.
It's a very different world today. Vernon, like those who came before, his contemporaries, and those who followed were unique, products of their time, environment, and individual psychology.
I would not equate Vernon with Prometheus as he was primarily influential in the amateur magic community. There were magicians who were far more influential in the professional realm - first Cardini and then Channing Pollock changed the look and approach of review-type acts along with Benny Chavez who trained a number of similar performers as he took advantage of the GI Bill; Thurston changed the look and feel of the big magic show when he took over Kellar's show; Dunninger inspired generations of mentalists with his one-man approach, etc.
Read more magic history, Chris and you'll come up with better questions.
