Roy Chapman Andrews was an American explorer, adventurer and naturalist who became the director of the American Museum of Natural History. He is primarily known for leading a series of expeditions in China in the early 20th century into the Gobi Desert and Mongolia. The expeditions made important discoveries and brought the first-known fossil dinosaur eggs to the museum. His popular writings about his adventures made him famous.
Quick, entertaining read. Much of the science is out of date, and the style is both non-pc and rather florid and lamarckian, but the book provides an interesting look at how things were when these discoveries were much more recent by one of the discoverers himself.
