Pellucidar is a fictional Hollow Earth invented by American writer Edgar Rice Burroughs for a series of action adventure stories. In a crossover event between Burroughs' series, there is a Tarzan story in which the Ape Man travels into Pellucidar.The stories initially involve the adventures of mining heir David Innes and his inventor friend Abner Perry after they use an "iron mole" to burrow 500 miles into the Earth's crust. Later protagonists include indigenous caveman Tanar and additional visitors from the surface world, notably Tarzan, Jason Gridley, and Frederich Wilhelm Eric von Mendeldorf und von Horst.Edgar Rice Burroughs (September 1, 1875 - March 19, 1950) was an American writer best known for his creations of the jungle hero Tarzan and the heroic Mars adventurer John Carter, although he produced works in many genres. Aiming his work at the pulps, Burroughs had his rst story, Under the Moons of Mars, serialized by Frank Munsey in the February to July 1912 issues of The All-Story - under the name "Norman Bean" to protect his reputation. Under the Moons of Mars inaugurated the Barsoom series and earned Burroughs US$400 ($9,927 today). It was rst published as a book by A. C. McClurg of Chicago in 1917, entitled A Princess of Mars.In a Paris Review interview, Ray Bradbury said of Burroughs that "Edgar Rice Burroughs never would have looked upon himself as a social mover and shaker with social obligations. But as it turns out - and I love to say it because it upsets everyone terribly - Burroughs is probably the most influential writer in the entire history of the world." Bradbury continued that "By giving romance and adventure to a whole generation of boys, Burroughs caused them to go out and decide to become special." In Something of Myself (published posthumously in 1937) Rudyard Kipling wrote: "My Jungle Books begat Zoos of them. But the genius of all the genii was one who wrote a series called Tarzan of the Apes."This classic title has been published by RADLEY BOOKS.
