4. Henry Fairfield Osborn (1857-1935)

Henry Fairfield Osborn’s tenure as President of the American Museum of Natural History marked a golden era in the institution’s history, particularly for dinosaur research and display.

President of the American Museum of Natural History

Osborn’s vision transformed the American Museum of Natural History into a world leader in paleontology. He spearheaded the development of its fossil halls, ensuring that the public had access to the wonders of prehistoric life. His leadership saw the Museum’s fossil collections expand exponentially, becoming a cornerstone for both research and education in the field.

Conducted extensive research on brontotheres and dinosaurs

Osborn’s scientific work was as broad as it was deep, with a keen focus on the massive herbivores known as brontotheres, as well as on dinosaurs. He was a prolific writer and thinker, publishing extensively on the evolutionary history and biology of these ancient beasts. His contributions significantly advanced our understanding of dinosaur taxonomy and evolution.

5. Edwin Colbert (1900-2001)

Edwin Colbert’s extensive fieldwork and research significantly broadened the scope of dinosaur paleontology with new discoveries and insights.
