What is the name of the scientist created by Arthur Conan Doyle in 'The Lost World'?

The scientist created by Arthur Conan Doyle in 'The Lost World' is Professor Challenger. His full fictional name is George Edward Challenger, an aggressive, brilliant, and often intimidating scientist who leads the expedition at the heart of the novel.

Challenger first appeared in Doyle's 1912 adventure novel, where he claims that prehistoric animals still survive on an isolated plateau in the Amazon basin. Journalist Edward Malone joins Challenger, Professor Summerlee, and Lord John Roxton on an expedition to investigate the claim. The group discovers dinosaurs, pterosaurs, and other ancient creatures in the remote lost world.

Unlike the controlled and analytical Sherlock Holmes, Challenger is physically imposing, explosive-tempered, and openly combative. Yet he is also courageous, inventive, and committed to proving genuine discoveries. Doyle reportedly based aspects of the character on explorer Percy Fawcett and physiologist William Rutherford.

Dr. Watson and Professor Moriarty belong to the Sherlock Holmes stories, not Challenger's original series. Professor Stanley is not the scientist introduced in 'The Lost World'. Challenger later returned in works including 'The Poison Belt' and 'The Land of Mist'.
