Sommario/riassunto

Kate Douglas Wiggin, (1856-1923) was an American children's author and educator. She was born in Philadelphia, and was of Welsh descent. She started the first free kindergarten in San Francisco in 1878. With her sister in the 1880s she also established a training school for kindergarten teachers. Her best known books are The Birds' Christmas Carol, Polly Oliver's Problem, A Cathedral Courtship, New Chronicles of Rebecca and Rebecca of Sunnybrook Farm.
