Arthur Conan Doyle (22 May 1859 – 7 July 1930) was a British writer and physician best known for inventing the character of Sherlock Holmes.
The Lost World, perhaps Conan Doyle's second most famous creation, concerns living dinosaurs in South America, possibly inspired by the reports of Percy Fawcett. In the Lost World he connects living dinosaurs with stories of the curupira (actually an ape-like creature). The novel served as youthful inspiration for several notable cryptozoologists. Bernard Heuvelmans, the "Father of Cryptozoology", first developed an interest in unknown animals after reading The Lost World and Jules Verne's 20,000 Leagues Under the Sea. Bill Gibbons, who has led several expeditions to the Congo in search of the mokele-mbembe, first became interested in the subject of living dinosaurs after seeing a film adaptation of The Lost World as a child.
Conan Doyle also wrote novels on hypothetical aerofauna (The Horror of the Heights) and surviving prehistoric bears (The Terror of Blue John Gap).
