Today is the 103rd birthday of the late Earl Tupper, a tinkerer who set out to be a 20th century-version of Leonardo da Vinci. In the fashion of Leonardo,Tupper kept an elaborately illustrated notebook of his own myriad inventions, which included pants with a permanent crease, a fish-powered automobile, a convertible top for rumble seats, and a dagger-shaped comb that could be clipped to a person’s belt. Alas, none of these innovations caught on, but after World War II, Tupper did manage to start his own small plastics company, which eked out a profit making inexpensive beads and soap containers. But then Tupper convinced a reluctant DuPont to give him some pure polyethylene pellets. After tinkering with his machines, he devised a way of molding the pure plastic into what he called the “wonderbowl,” a revolutionary new container for keeping leftovers fresh. Sales were slow until a housewife named Brownie Weis pitched him on an ingenious social marketing scheme, in which Tupper’s containers would be peddled directly to consumers at neighborhood gatherings. The rest, of course, is history. And with that, here are the amazingly well-preserved, juicy stories of the day.
