we’ve had threads before about movies in which the heroes are switched to Americans, when the reality was quite different (The Great Escape and U-571, for two examples), and the recent thread on the War of 1812 points out how that conflict is taught in US schools with a definite US bias, but the American “centrism” of a lot of our scooling and of articles is a great deal more widespread. I’m surprised how much the achievements of others are overlooked in this regard.
as an example, consider Ironclads. They make a big deal about the Monitor and the Merrimack in US schooling. even ignoring the fact that the “Merrimack” was actually rebuilt considerably and rechristened the “Virginia”, therre’s the fact that these were by no means the first ironclad ships, being preceded by the French Gloire and the British Warrior (which still exists)

Or take the example of Submarines. From most accounts you’d get the impression that Bushnell’s Turtle was the first practical sub, although there are examples of operating British and German 9and maybe French) cases.
Or steamships – we were taught that Fulton’s Clermont was the first. Again, the name is wrong (Fulton never named it the “Clermont”. It was called the “North River Steam Boat”, and later “THe North River of Clermont”, since it docked at Clermont), but plenty of examples preceded it. I have a British book here that has Fulton’s ship sixth ion a progression of operating steambots goinn back almost a century earlier.
Even in art and pop culture. American references tend to declare Outcalt’s "The Yellow Kid’ as the first comic strip, but he was preceded by the British “Alley Sloper”, and arguably by the German “Max und Moritz”
One can always ferret out earlier examples of things if one looks long and hard, but these examples aren’t of really obscure things – they were well-known in theior country of origin, and often in the rest of the world. They just seem to be cases of not looking beyond our own shiores in compiling lists of early cases.
