Tarzan of the Apes is a novel by American writer Edgar Rice Burroughs, the first in a series of books about the title character Tarzan. It was first published in the pulp magazine The All-Story in October 1912. The story follows Tarzan's adventures, from his childhood being raised by apes in the jungle, to his eventual encounters with other humans and Western society. So popular was the character that Burroughs continued the series into the 1940s with two dozen sequels. For the novel's centennial anniversary, Library of America published a hardcover edition based on the original book with an introduction by Thomas Mallon in April 2012 (ISBN 978-1-59853-164-0). Scholars have noted several important themes in the novel: the impact of heredity on behavior; racial superiority; civilization, especially as Tarzan struggles with his identity as a human; sexuality; and escapism.
