Hildegard G. Frey

An American author born in Cleveland, Ohio in 1891, she is generally identified as Hildegard Gertrude Frey and published as Hildegard G. Frey. She is remembered chiefly for writing the Camp Fire Girls novels, a series for young readers tied to the Camp Fire movement.

Her best-known books were published from 1916 into the early 1920s and include The Camp Fire Girls in the Maine Woods, The Camp Fire Girls at School, The Camp Fire Girls Go Motoring, and later titles such as The Camp Fire Girls Do Their Bit and The Camp Fire Girls Solve a Mystery. The books follow the Winnebagos through adventures that mix humor, teamwork, travel, and practical problem-solving.

Much of her personal life is not well documented in the sources readily available online, but her fiction has remained accessible through library catalogs, reprints, and Project Gutenberg editions. That continued availability has helped keep her work in circulation for readers interested in classic girls' adventure stories and early American juvenile series fiction.
