Best known for a vividly illustrated 1907 children's novel set in prehistoric times, this early 20th-century writer introduced young readers to everyday life in the Stone Age. Her work blends adventure with simple, educational storytelling.

by Margaret A. McIntyre
Margaret A. McIntyre is a little-documented early 20th-century author best known for The Cave Boy of the Age of Stone. Reliable catalog and edition records connect her with that book, which was published in 1907 and later preserved through Project Gutenberg and other public-domain archives.
The novel was written for young readers and uses story, pictures, and scenes from daily life to imagine how prehistoric families lived. Modern summaries of the book describe it as an educational children's novel, and surviving editions show that it was illustrated by Irma Deremeaux.
Very little confirmed biographical information about McIntyre herself appears to be available in major public sources. Because of that, her reputation today rests mainly on this one enduring work and its continued circulation in digital archives and reprints.
