Kate Douglas Wiggin 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. 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.

Rebecca of Sunnybrook Farm is a classic American 1903 children's novel by Kate Douglas Wiggin that tells the story of Rebecca Rowena Randall and her aunts, one stern and one kind, in the fictional village of Riverboro, Maine. Rebecca's joy for life inspires her aunts, but she faces many trials in her young life, gaining wisdom and understanding. Wiggin wrote a sequel, New Chronicles of Rebecca. Eric Wiggin, a grand-nephew of the author, wrote updated versions of several Rebecca books, including a concluding story. The story was adapted for the theatrical stage and filmed three times, once with Shirley Temple in the title role, as well as a Japanese animated short as part of the Anime Tamago project.
