Milne is most famous for his two "Pooh" books about a boy named Christopher Robin after his son, Christopher Robin Milne (1920–1996), and various characters inspired by his son's stuffed animals, most notably the bear named Winnie-the-Pooh. Christopher Robin Milne's stuffed bear, originally named Edward, was renamed Winnie after a Canadian black bear named Winnie (after Winnipeg), which was used as a military mascot in World War I, and left to London Zoo during the war. "The Pooh" comes from a swan the young Milne named "Pooh". E. H. Shepard illustrated the original Pooh books, using his own son's teddy Growler ("a magnificent bear") as the model. The rest of Christopher Robin Milne's toys, Piglet, Eeyore, Kanga, Roo and Tigger, were incorporated into A. A. Milne's stories, and two more characters – Rabbit and Owl – were created by Milne's imagination. Christopher Robin Milne's own toys are now on display in New York where 750,000 people visit them every year.
