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 in 1878 (the Silver Street Free Kindergarten). With her sister during the 1880s, she also established a training school for kindergarten teachers. Kate Wiggin devoted her adult life to the welfare of children in an era when children were commonly thought of as cheap labor.

Wiggin went to California to study kindergarten methods. She began to teach in San Francisco with her sister Nora assisting her, and the two were instrumental in the establishment of over 60 kindergartens for the poor in San Francisco and Oakland. She moved from California to New York, and having no kindergarten work on hand, devoted herself to literature. She sent The Story of Patsy and The Bird's Christmas Carol to Houghton, Mifflin & Co. who accepted them at once. Besides the talent for story-telling, she was a musician, sang well, and composed settings for her poems. She was also an excellent elocutionist. Her first literary work was Half a Dozen Housekeepers, a serial story which she sent to St. Nicholas. After the death of her husband in 1889, she returned to California to resume her kindergarten work, serving as the head of a Kindergarten Normal School. Some of her other works included Cathedral Courtship, A Summer in a Canon, Timothy's Quest, The Story Hour, Kindergarten Chimes, Polly Oliver's Problem, and Children's Rights.

In the 1980s and 1990s, Wiggin's first husband's distant cousin, Eric E. Wiggin, published updated versions of some books in Kate Douglas Wiggin's Rebecca of Sunnybrook Farm series. He later published his own addition to the series, entitled, Rebecca Returns to Sunnybrook. Eric E. Wiggin extended Kate Douglas Wiggin's series after years of writing Christian literature, newspaper articles, and other children's books. Eric E. Wiggin's books sold best among his target audience of homeschoolers; with their help, his updated novels and his new addition to the series have sold more than 50,000 copies.

Many of Kate Douglas Wiggin's novels were made into movies. Perhaps the most famous film adaptation of her books is the 1938 film, which stars Shirley Temple. (wikipedia.org)
