Outside of the province of the Märchen, which constitutes so rich a field in German literature, there is no writer better known or better loved in the young German-speaking world than Johanna Spyri. Her stories, written "for children and those who love children," are read and reread as something that never grows old. The secret of this charm lies, above all, in the author's genuine love of children, as shown in her sympathetic insight into the joys, the hopes, and the longings of childhood, and in her skillful selection of characteristic details, which creates an atmosphere of reality that is rare in books written for children. Johanna Heusser Spyri was born in the little Swiss town of Hirzel, canton of Zürich, in 1827, and died in Zürich in 1901. She wrote especially for young people, her writings dealing mostly with Swiss mountain life and portraying the thrifty, industrious nature of the people. The stories are sometimes sad,—for the peasant's life is full of hardships,—but through them all a fresh mountain breeze is blowing and a play of sunlight illumines the high Alps.

Johanna Louise Spyri was a Swiss-born author of novels, notably children's stories, and is best known for her book Heidi. Born in Hirzel, a rural area in the canton of Zurich, Switzerland, as a child she spent several summers near Chur in Graubünden, the setting she later would use in her novels.
