There’s a story out there… a story you’ll find on dozens, maybe hundreds of websites, about the invention of the casserole:

“In 1866, Elmire Jolicoeur, a French Canadian immigrant, invented the precursor of the modern casserole in Berlin, New Hampshire.”

That’s from Wikipedia. If you don’t trust Wikipedia, you can also find this attribution in print, too.
