Johanna Spyri 
Heidi 

Heidi is a work of children’s fiction published in 1881 by Swiss author Johanna Spyri, originally published in two parts as Heidi: Her Years of Wandering and Learning and Heidi: How She Used What She Learned. One of Switzerland’s best-loved exports, the little mountain girl Heidi, was a cult figure in her younger years but she disappeared from public life decades ago. Johanna Spyri’s heart-warming story was based on the real-life adventures of Heidi Schwaller, 92, who grew up near Chur in the Swiss Alps. 'It was spiteful Clara who dyed Heidi’s naturally blond hair a horrible blue, because she was jealous of her. The Swiss heroine was royally fooled by the German girl. The moral of the story: protect your blondness, Swiss girls!’.
