A. A. Milne set. Milne lived on the northern edge of the forest at Cotchford Farm, , and took his son walking there. E. H. Shepard drew on the landscapes of Ashdown Forest as inspiration for many of the illustrations he provided for the Pooh books. The adult Christopher Robin commented: "Pooh's Forest and Ashdown Forest are identical." Popular tourist locations at Ashdown Forest include: "Galleon's Lap", "The Enchanted Place", the "Heffalump Trap" and "Lone Pine", "Eeyore’s Sad and Gloomy Place", and the wooden "Pooh Bridge" where Pooh and Piglet invented Poohsticks. Not yet known as Pooh, he made his first appearance in
What Is to Be Done? (novel) based on his own ideas of moral responsibility. Vladimir Lenin, however, found it inspiring and named a 1902 pamphlet "What Is To Be Done?". Lenin is said to have read the book five times in one summer, and according to Professor Emeritus of Slavic and Comparative Literature at Stanford, Joseph Frank, 'Chernyshevsky's novel, far more than Marx's "Capital", supplied the emotional dynamic that eventually went to make the Russian Revolution.' The novel mentions (in the 4th dream of Vera Pavlovna) aluminium as the "metal of the future". In fact aluminium became widely used only starting with World War I (1914).
