Charles W. Gilmore was a prolific scientist. He was employed by the U.S. National Museum in 1903 where he worked until his death in 1945. Originally hired as a preparator to work on the extensive O.C. Marsh dinosaur collection that was transferred from Yale University to the U.S. National Museum in the late 19th century, Gilmore later became curator of fossil reptiles. He was in charge of mounting the world's first Triceratops skeleton for exhibition at the Smithsonian Institution, as well as 23 other mounts on exhibit. He published 170 scientific papers including monographic studies on the osteology of Apatosaurus and Camptosaurus and the osteology of the carnivorous and armored dinosaurs.
