Sir Arthur Ignatius Conan Doyle, DL (22 May 1859 – 7 July 1930) was a Scottish physician and writer, most noted for his stories about the detective Sherlock Holmes, which are generally considered a major innovation in the field of crime fiction, and for the adventures of Professor Challenger. He was a prolific writer whose other works include science fiction stories, historical novels, plays and romances, poetry, and non-fiction.

In the sketch book are Maple White's drawings of the prehistoric beasts, birds and ape men which he has seen on his travels. Professor challenger is excited when he sees the drawings and decides to find out if there is a Lost World in the Amazon forest where dinosaurs, Pterodactyls and ape men still exist.
