Kate Douglas Wiggin was an American educator, author, and composer who lived from September 28, 1856, until August 24, 1923. She also created collections of children's songs in addition to writing children's books, most famously the classic Rebecca of Sunnybrook Farm. In San Francisco, she established the city's first free kindergarten in 1878. She also started a kindergarten teacher training program in the 1880s with her sister. In an era when kids were often seen as cheap labor, Kate Wiggin dedicated her whole life to the welfare of kids. Wiggin traveled to California to research kindergarten instruction. She started teaching in San Francisco with the help of her sister Nora, and the two were crucial in establishing more than 60 kindergartens for the underprivileged in Oakland and San Francisco. She relocated from California to New York, and because she was out of kindergarten assignments, she focused on literature. She had storytelling ability in addition to being a good singer, guitarist, and composer of settings for her poems. She was a skilled orator as well.
