Professor Challenger #1 / The Lost World is a novel released in 1912 by Sir Arthur Conan Doyle concerning an expedition to a plateau in the Amazon basin of South America where prehistoric animals (dinosaurs and other extinct creatures) still survive. It was originally published serially in the popular Strand Magazine and illustrated by New-Zealand-born artist Harry Rountree during the months of April–November 1912. The character of Professor Challenger was introduced in this book. The novel also describes a war between Native Americans and a vicious tribe of ape-like creatures. To mark the novel's 100th anniversary, a special collector's centenary edition was released in New Zealand in October 2012 in the format of an illustrated expedition report that also includes analytical chapters by several leading authorities.
