Earl Tupper

Tupper died in Costa Rica on October 5, 1983, at the age of 76.

In 1969, Tupper donated 428 acres of land in Smithfield, Rhode Island, to his alma mater, Bryant College (now named Bryant University). The land was developed into the college's new campus, which opened in 1971. The campus in Providence where Tupper had once studied was sold to Brown University.

The corporate headquarters was moved from Massachusetts to Orlando, Florida. After his falling-out with Wise, which resulted in her dismissal in 1958, Tupper sold The Tupperware Company for $16 million to Rexall. Shortly afterward, he divorced his wife, gave up his U.S. citizenship to avoid taxes, and bought an island just off the coast of Costa Rica or according to other sources Isla San José

Based on a marketing strategy developed by Wise and early pioneers Tom and Ann Damigella from Everett, Massachusetts, Tupperware was withdrawn from sale in retail stores in the early 1950s and Tupperware "parties" soon became popular in homes. This was the first instance of what became known as "party plan" marketing.

Tupper founded the Tupperware Plastics Company in 1938, and in 1948 the company introduced Tupper Plastics to hardware and department stores. Around 1946, he joined forces with Brownie Wise, who caught his attention after she made a lengthy phone call to his office in South Grafton, Massachusetts, during which she explained her extraordinary success selling Tupperware via home parties.

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.
