The author was an amateur naturalist, wildlife photographer, and one of the earliest women to form a movie studio and production company. She wrote some best-selling novels and well-received columns in national magazines, such as McCalls. Her works were translated into several languages, including Braille, and Stratton-Porter was estimated to have had 50 million readers around the world. She used her position and income as a well-known author to support conservation of Limberlost Swamp and other wetlands in the state of Indiana. Her novel A Girl of the Limberlost was adapted four times as a film, most recently in 1990 in a made-for-TV version.One of Stratton-Porter's last novels, Her Father's Daughter (1921), was set outside Los Angeles. She had moved about 1920 for health reasons and to expand her business ventures into the movie industry. This novel presented a unique window into Stratton-Porter's feelings about World War I-era racism and nativism, especially relating to immigrants of Asian descent. Stratton-Porter died in Los Angeles in 1924 when her limousine was struck by a streetcar.
