Mother Carey's chickens

Kate Douglas Wiggin (September 28, 1856 – August 24, 1923) was an American educator, author and composer. She wrote children's stories, most notably the classic children's novel Rebecca of Sunnybrook Farm, and composed collections of children's songs. She started the first free kindergarten in San Francisco, the Silver Street Free Kindergarten, in 1878. With her sister Nora during the 1880s, she also established a training school for kindergarten teachers. Wiggin devoted her adult life to the welfare of children in an era when children were commonly thought of as cheap labor.
