Whose expeditions first made the Gobi Desert a major subject of scientific study?

Roy Chapman Andrews led the Central Asiatic Expeditions from 1922 to 1930, which explored the Gobi Desert and produced major fossil discoveries. His teams found dinosaur eggs and a rich record of ancient life, helping turn the Gobi into one of the world’s most important fossil regions. The expeditions also expanded scientific knowledge of the desert’s geology, climate, and terrain. Andrews became widely known as a bold explorer as well as a museum scientist.
