Milne named the character Winnie-the-Pooh after a teddy bear owned by his son, Christopher Robin Milne, who was the basis for the character Christopher Robin. His toys also lent their names to most of the other characters, except for Owl and Rabbit, as well as the Gopher character, who was added in the Disney version. Christopher Robin's toy bear is now on display at the Main Branch of the New York Public Library in New York.^[1]

Harry Colebourne and Winnie 1914

Christopher Milne had named his toy bear after Winnie, a bear which he often saw at London Zoo, and "Pooh", a swan they had met while on holiday. The bear cub was purchased from a hunter for $20 by Canadian Lieutenant Harry Colebourn in White River, Ontario, Canada, while en-route to England during the First World War. He named the bear "Winnie" after his hometown in Winnipeg, Manitoba. "Winnie" was surreptitiously brought to England with her owner, and gained unofficial recognition as The Fort Garry Horse regimental mascot. Colebourne left Winnie at the London Zoo while he and his unit were in France; after the war she was officially donated to the zoo, as she had become a much loved attraction there.^[2] Pooh the swan appears as a character in its own right in When We Were Very Young.

In the first chapter of Winnie-the-Pooh, Milne offers this explanation of why Winnie-the-Pooh is often called simply "Pooh": "But his arms were so stiff ... they stayed up straight in the air for more than a week, and whenever a fly came and settled on his nose he had to blow it off. And I think — but I am not sure — that that is why he is always called Pooh."

Crotchford Farm, Milnes' home in Ashdown Forest in East Sussex, England, was the basis for the setting of the Winnie-the-Pooh stories. The name of the fictional "Hundred Acre Wood" is reminiscent of the Five Hundred Acre Wood, which lies just outside Ashdown Forest and includes some of the locations mentioned in the book, such as the Enchanted Place.^[3]

The origin of the Poohsticks game is at the footbridge across a tributary of the River Medway near Upper Hartfield, close to the Milnes' home at Posingford Farm. It is traditional to play the game there using sticks gathered in nearby woodland. When the footbridge required replacement in recent times the engineer designed a new structure based closely on the drawings (by E H Shepherd) of the bridge in the original books, as the bridge did not originally appear as the artist drew it. There is an information board at the bridge which describes aspects of how to play the game.
