Elizabeth M. Duffield

Born in 1895 and later known as Elizabeth M. Duffield Ward, she wrote both under her own name and for the Stratemeyer Syndicate, the powerhouse behind many classic juvenile series. Reliable sources available here consistently describe her as a prolific Syndicate writer, and also note that she was the daughter of John William Duffield, who likewise wrote extensively for the Syndicate.

Alongside her own Lucile Payton books, she is credited in the sources consulted with work on several well-known series, including Kay Tracey, Ruth Fielding, Betty Gordon, The Outdoor Girls, and the Blythe Girls books. That combination of named authorship and ghostwriting helps explain why her influence on children's series fiction was larger than her public profile might suggest.

She died in 1983. While detailed biographical material appears to be limited in the sources I could confirm, the record that does emerge is of a steady, versatile writer whose stories helped shape popular girls' adventure fiction in the first half of the twentieth century.
