Eleanor Hodgman Porter

Eleanor H. Porter is most widely recognized for her novel "Pollyanna," which introduced the concept of "the Pollyanna principle" or "Pollyannaism" into popular culture, referring to an optimistic bias.

Several film adaptations of "Pollyanna" have been produced, including a notable 1960 Disney film starring Hayley Mills, and earlier versions from the silent film era.

The original "Pollyanna" novel is followed by "Pollyanna Grows Up." While Porter wrote the first two, other authors continued the series with additional books.
