Henry Fairfield Osborn
Henry Fairfield Osborn (1857-1935) "was the leader of the American Museum of Natural History for a quarter of a century, and to him must go the lion's share of the credit for its movement into the limelight during that period as the world's top such institution. Osborn was also a professor at Columbia and head of the vertebrate paleontology department at the AMNH for many years. Further, he was a world-renowned vertebrate paleontologist who published nearly a thousand works and well over ten thousand pages of writings. Osborn had a bent for theorizing, especially when it came to evolution: he was not a fan of natural selection, preferring to recognize various "laws," mostly of morphological trends, that were based on his paleontological investigations. At the same time, he distrusted experimental approaches, or the advances being made in genetics. He was not considered a good taxonomist (many of the names he applied have since been overturned), and had some strange views in the direction of eugenics. Still, for all these foibles he was a force to be reckoned with, both as a synthesizer of information and popularizer of same, and as a progressive administrator." 
His son was Fairfield Osborn.
