First edition
Alan Alexander Milne was an English writer best known for his books about the teddy bear Winnie-the-Pooh, as well as for children's poetry. Milne was primarily a playwright before the huge success of Winnie-the-Pooh overshadowed all his previous work. Milne served in both world wars, as a lieutenant in the Royal Warwickshire Regiment in the First World War and as a captain in the Home Guard in the Second World War.
