• Winnie the Pooh - Fictional character created by A. A. Milne

  Winnie-the-Pooh (also known as Edward Bear, Pooh Bear or simply Pooh) is a fictional anthropomorphic teddy bear created by the English author A. A. Milne and the English illustrator E. H. Shepard. Winnie-the-Pooh first appeared by name in a children's story commissioned by London's Evening News for Christmas Eve 1925. The character is inspired by a stuffed toy that Milne had bought for his son Christopher Robin in Harrods department store, and a bear named Winnie they had viewed at London Zoo. The first collection of stories about the character is the book Winnie-the-Pooh (1926), and this was followed by The House at Pooh Corner (1928). Milne also included a poem about the bear in the children's verse book When We Were Very Young (1924) and many more in Now We Are Six (1927). All four volumes were illustrated by E. H. Shepard. The stories are set in and around the Hundred Acre Wood, which was inspired by Five Hundred Acre Wood in Ashdown Forest in East Sussex—situated 30 miles (48 km) south of London—where the Londoner Milne's country home was located. The Pooh stories have been translated into many languages, including Alexander Lenard's Latin translation, Winnie ille Pu, which was...
