Charles R. Knight (1874-1953) was one of the first American painters to depict dinosaurs, providing imaginative and largely scientifically based renditions of the extinct beasts in real-world settings. His realistic renderings were referred to as restorations. During a time when dinosaurs were capturing the fascination of people across the country, Knight's ground-breaking images combined paleontology and artistry to create some of the most popular museum displays of his day. Though somewhat speculative and not entirely based on solid evidence, Knight's paintings put flesh on creatures no one had ever seen, and he helped shape the image of dinosaurs that lives in public consciousness to this day.
