Hildegard G. Frey

Hildegard G. Frey, also listed as Hildegarde Gertrude Frey, was an American author born in Cleveland, Ohio, on December 18, 1891, and she died there on May 8, 1957. She is chiefly remembered for writing entries in the Camp Fire Girls series, a popular line of children's novels from the 1910s and early 1920s.

Her best-known books center on the Winnebago Camp Fire Girls and include titles such as 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 Do Their Bit. Contemporary listings and later bibliographies connect her name with a substantial run of these books, which were marketed as stories tied to the Camp Fire Girls organization.

Today, Frey is mostly read by fans of vintage girls' fiction, scouting history, and early series books for young readers. Her stories are remembered for their cheerful energy, group adventure, and period detail, offering a window into how publishers imagined independence and friendship for girls in the early 1900s.
