This piece is adapted from David Harsanyi’s new book, “First Freedom: A Ride Through America’s Enduring History with the Gun†(Threshold Editions).1. Kentucky RifleMartin Meylin has been credited with being the first great American gunmaker and inventor of the Pennsylvania long rifle—which was to become known as the Kentucky long rifle (“Kentucky,†in those days, being anything in the wilderness west of Pennsylvania). Meylin’s small cobblestone workshop still stands off a two-lane road in Lancaster. Local schools are named after him. Plaques have been erected in his honor. State politicians have even written legislation commemorating his contribution to American life.
Well, while we know that Meylin left his home in Zurich, Switzerland, around 1710, and ended up in the German-speaking area of Lancaster County—a place that would become the center of American gun innovation for more than a century—we don’t know much else. And while it is tidy to give a single inventor credit for the gun, it’s probably the case that numerous inventors and blacksmiths engineered the Kentucky rifle over a period of decades.
