American manufacturer Earl S. Tupper, inventor of Tupperware, was born July 28, 1907 in New Hampshire. In the 1930's, Tupper invented a flexible, lightweight material that was used to make plastic gas masks during World War II. He then turned his attention to consumer products and created Tupperware - a line of plastic, airtight food storage containers. Sales languished in stores until it was discovered that home demonstrations better proved the value of the product, and thus, the Tupperware Party was born. It has since become a global institution in more than 100 countries.

Clarke or by watching the PBS home video Tupperware!, which offers an interesting look at the quirky, and often bizarre, history of this household name.
