Earl Silas Tupper (July 28, 1907 – October 3, 1983) was an American businessman and inventor, best known as the inventor of Tupperware, an airtight plastic container for storing food, and for founding the related home products company that bears his name, Tupperware Plastics Company. Early life and career Tupper was born on a farm in Berlin, New Hampshire. The Tupper family moved from Berlin when he was three years old, spending the rest of his youth growing up on different farms in central Massachusetts. After studying at Bryant College (now Bryant University) in Providence, Rhode Island, he began a landscaping and nursery business until the Great Depression forced the business into bankruptcy. He then got a job with the DuPont chemical company. Creation of Tupperware Using black, inflexible pieces of polyethylene slag, a waste product of the oil refining process given to him by his supervisor at DuPont, Tupper purified the slag and molded it to create lightweight, non-breakable containers, cups, bowls, plates, and even gas masks that were used in World War II. He later designed liquid-proof, airtight lids, inspired by the secure seal of paint can lids.
