Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American professor of paleontology. A prolific fossil collector, Marsh was one of the preeminent paleontologists of the nineteenth century. Among his legacies are the discovery or description of dozens of new species—including Stegosaurus and Triceratops—and theories on the origins of birds. He spent his academic career at Yale College and was president of the National Academy of Sciences. (From Wikipedia)
