An inventor from Massachusetts named Earl D. Tupper invented Tupperware in 1942.
In the 1930s, Tupper, a chemist at Du Pont, experimented with a new durable plastic called polyethylene.
Tupper thought it could be used for all types of housewares, and he developed some test products.
The first piece of Tupperware, a bathroom cup, was introduced to department stores in 1945. It outsold its competitors.
Tupperware’s sales mushroomed when Tupper created the marketing device of the home party. By 1954, in-home sales topped $25 million.
