[1][2] Pierson became a successful author of children's books, with her most popular works being quasi-naturalistic stories about animals.
Like similar animal tales written a few years later by Thornton Burgess, her stories often carry a moral, hinted at in titles such as "The Thrifty Deer-Mouse".
[1] Another of her series features the adventures of the three Miller children and a house called Pencroft, which was also the name of the summer home in Omena, Michigan, that Pierson built with her income as a writer.
[2] She married hardware store owner John Williams Smith Pierson in 1894, and they resided in Stanton, Michigan, in the early 1900s.
[2] They had a child who died shortly after birth, and they later adopted two sons, John Howard Pierson and Harold Dillingham.
