I think more people outside the USA may know about Jefferson that those inside.

USA has 300+ million people. Let's be super generous and say 2/3 of Americans actually know who he is, beyond being on money. That makes it about 200+ million. That's not even counting all the US territories.

I'm Canadian and we have 30+ million. I know FAAAAAAR more about American politics and history than Canadian. I am not alone. That makes it about 20+ million.

The American propaganda engine is the greatest in the world. I've art-directed on movies shot in Toronto pretending to be American. It's just how it goes. All across Europe, Asia, Africa, South America and Australia people watch American movies and television.

Of 8 billion people, half are dirt poor, but there's still a good chance enough know of Jefferson, not even 1 in 10 are necessary.

Jefferson is on par with historical figures like Shakespeare, Beethoven, Napoleon, and Caesar - though very different, from different countries, all well known.

Ping me whenever.
