Christopher Robin's bear in the stories by A. A. Milne; Winnie-the-Pooh (1926) is the first of the books, and Pooh, the ‘bear of very little brain’ with his liking for honey, is the central character of the nursery animals.
Winnie was originally the name of a black bear which was the mascot of a Canadian regiment, and which was brought to London zoo (where it remained) while the regiment was fighting in France in the First World War; Pooh was borrowed from the name first given by Christopher Robin to a swan.
