Winnie the Pooh was based on a real bear
There was a Canadian soldier who bought a black bear cub from a hunter at the time of World War I. Gradually that cub became his pet and mascot for his troop. The bear was named Winnipeg and was later given to the London Zoological Gardens where Christopher Robin Milne, the author of Winnie the Pooh, A.A. Milne's son developed a great liking of the bear that he named his teddy bear after that cub bear.
