When Abner Perry invents a vehicle that essentially drills through the earth, he takes it to his good friend (and independently wealthy man about town) David Ennis. And what else can they do Drill down into the earth, of course. What they find there isn't what we'd expect: it's an inner world called Pellicidar, a place where the sun neither sets nor rises - because what appears to be the sun is no sun at all, but the molten core of the earth. Pellucidar is a great fun fantasy world, full of dragons, apes, and reptiles and Weird Things. It's ruled by sorcerous royalty (the princess falls in love with Our Hero, of course) and of course our heroes end up hip-deep in dragons...
Edgar Rice Burroughs (1875 - 1950)
Edgar Rice Burroughs was a prolific American author of the 'pulp' era. The son of a Civil War veteran, he saw brief military service with the 7TH U.S. Cavalry before he was diagnosed with a heart problem and discharged. After working for five years in his father's business, Burroughs left for a string of disparate and short-lived jobs, and was working as a pencil sharpener wholesaler when he decided to try his hand at writing. He found almost instant success when his story 'Under the Moons of Mars' was serialised in All-Story Magazine in 1912, earning him the then-princely sum of $400.
Burroughs went on to have tremendous success as a writer, his wide-ranging imagination taking in other planets (John Carter of Mars and Carson of Venus), a hollow earth (Pellucidar), a lost world, westerns, historicals and adventure stories. Although he wrote in many genres, Burroughs is best known for his creation of the archetypal jungle hero, Tarzan. Edgar Rice Burroughs died in 1950.
