Hildegard G. Frey

Published as Hildegard G. Frey and also identified in library records as Hildegard Gertrude Frey, she was born in 1891 and died in 1957. Today she is chiefly remembered for writing books in the Camp Fire Girls series, a long-running line of children's novels centered on girls' outdoor adventures, teamwork, and character-building.

Her best-known titles include The Camp Fire Girls in the Maine Woods, The Camp Fire Girls at School, The Camp Fire Girls Go Motoring, and The Camp Fire Girls Solve a Mystery. The books follow lively groups of girls through camping trips, travel, school life, and wartime-era service, reflecting the era's enthusiasm for organized youth activities and wholesome adventure.

Although detailed biographical information about her appears to be scarce, her fiction has remained easy to find through library catalogs and public-domain editions. That lasting availability has helped keep her work alive for readers interested in vintage girls' series fiction and early twentieth-century juvenile literature.
