Eulalie Osgood Grover

Born in Mantorville, Minnesota, in 1873, Eulalie Osgood Grover became a popular American writer of children's books and primers. Archival and local history sources describe her as especially known for the Sunbonnet Babies series, which began with The Sunbonnet Babies' Primer in 1902.

Her books were created for beginning readers and often used a carefully limited vocabulary, with songs and lively illustrations that made reading feel friendly and fun. Collections of her papers note that these schoolroom books were used widely in the United States, and surviving titles such as Kittens and Cats, Mother Goose, and The Overall Boys show her gift for adapting familiar themes for young children.

Grover later lived in Winter Park, Florida, after moving there in 1926. She died in 1958, leaving behind a body of work that still offers a window into how early twentieth-century children first learned to read.
