Works specifically written for children. The earliest known illustrated children's book in English is Goody Two Shoes 1765, possibly written by Oliver Goldsmith. Fairy tales were originally part of a vast range of oral literature, credited only to the writer who first recorded them, such as Charles Perrault. During the 19th century several writers, including Hans Christian Andersen, wrote original stories in the fairy tale genre; others, such as the Grimm brothers, collected (and sometimes adapted) existing stories. Early children's stories were written with a moral purpose; this was particularly true in the 19th century, apart from the unique case of Lewis Carroll's Alice books. The late 19th century was the great era of children's literature in the UK, with Lewis Carroll, Beatrix Potter, Charles Kingsley, and J M Barrie. It was also the golden age of illustrated children's books, with such artists as Kate Greenaway and Randolph Caldecott. In the USA, Louise May Alcott's Little Women 1868 and its sequels found a wide audience. Among the most popular 20th-century children's writers in English have been Kenneth Grahame (The Wind in the Willows 1908) and A A Milne (Winnie the Pooh 1926) in the UK; and, in the USA, Laura Ingalls Wilder (Little House on the Prairie 1935), E B White (Stuart Little 1945, Charlotte's Web 1952), Dr Suess (Cat in the Hat 1957), and Maurice Sendak (Where the Wild Things Are 1963). Canadian Lucy Maud Montgomery's series that began with Anne of Green Gables 1908 was widely popular. examples include Robinson Crusoe by Daniel Defoe; the satirical Gulliver's Travels by Jonathan Swift, and Tom Sawyer 1876 and Huckleberry Finn 1884 by Mark Twain.
