Since the dawn of time, people have found nifty ways to clean up after the bathroom act. The most common solution was simply to grab what was at hand: coconuts, shells, snow, moss, hay, leaves, grass, corncobs, sheep’s wool—and, later, thanks to the printing press—newspapers, magazines, and pages of books. The ancient Greeks used clay and stone. The Romans, sponges and salt water. But the idea of a commercial product designed solely to wipe one’s bum? That started about 150 years ago, right here in the U.S.A. In less than a century, Uncle Sam’s marketing genius turned something disposable into something indispensable.
