Patricia St. John was a British author, and her connection to anime is solely as the writer of the original source material that was later adapted into an animated series. She was not an anime or manga creator herself. Her full name was Patricia Mary St. John, born on April 5, 1919, in Southampton, England, and she died on August 15, 1993. By profession, she was an evangelical writer and a missionary nurse, spending much of her life working in Morocco. She was a prolific author of children's fiction, often with a Christian theme.

Her most notable work in the context of anime is the children's novel Treasures of the Snow, first published in 1950. This book served as the basis for the 1983 Japanese anime television series The Alps Story: My Annette. The series was produced by the studio Nippon Animation, directed by Kōzō Kusuba, and ran for 48 episodes on Fuji TV. It is part of the prestigious World Masterpiece Theater (Calpis Children's Theater) lineup, a long-running series of anime adaptations of Western children's books. The story is set in the Swiss mountain village of Rossinière, drawing from St. John's memories of a year spent in Alpine Switzerland as a young person.

The thematic content of her writing, particularly Treasures of the Snow, often centers on themes of forgiveness, friendship, and moral growth, set against a backdrop of everyday life. The anime adaptation is noted for retaining a strong Christian moral tone, which is characteristic of St. John's original literary work. Beyond this single anime adaptation, her novel was also adapted into a live-action film, A Treasure in the Snow, in 1979.

Patricia St. John's significance to the anime industry is not as an original creator but as a source author. Her work became part of the World Masterpiece Theater franchise, which has been influential in introducing classic children's literature to a broad Japanese audience. Her identity as a British missionary writer whose work was adapted into a major Japanese animated series places her among a select group of Western authors whose stories were chosen for this series, which includes figures like Lucy Maud Montgomery and Johanna Spyri. However, there is no evidence or record of her having any direct involvement in the production of the anime adaptation, nor did she create any other original works specifically for the anime or manga medium.
