May Baldwin

Born in Lucknow, India, in 1862, May Baldwin was the daughter of the Rev. John Richard Baldwin and grew up in a family that later returned to England. Sources also note that she was educated in Germany and trained at Bishop Otter College in Chichester, which helps explain the confident school-setting details in her fiction.

Baldwin wrote many books for young readers, especially school stories such as A Popular Girl, A City Schoolgirl and Her Friends, Rooni, and A Riotous Term at St Norbert's. Her work often centers on friendship, ambition, mischief, and the everyday drama of girls' lives at school.

She died in 1950. While detailed biographical information is limited in the sources I found, her long list of books suggests a steady and popular career in children's fiction.
