Earl S. Tupper gave us Tupperware and thus an extended life on that casserole you don't want to eat. But he did a lot more than just give us a way to forget leftovers in the back of the refrigerator for 6 months. He had lots of ideas. Scholars can find his sketches in the archives of the Smithsonian’s National Museum of American History. For example, he developed an ice cream cone design with a gutter to prevent leakage. And he put a lot of thought into how women’s corsets should be designed.
But most importantly, Earl S. Tupper came up with a revolutionary form of naval propulsion. The fish-powered boat had a pair of wings that did not greatly slow down the boat, but prevented the fish from diving and escaping—or diving and taking the boat with it. We we don't use these today is beyond me.
