Charles Doolittle Walcott (1850-1927) was an American paleontologist, administrator of the Smithsonian Institution from 1907 to 1927. He was the Director of the USGS from 1894 to 1907. Walcott is best remembered for his discovery in 1909 of well-preserved fossils in the Burgess Shale of British Columbia, Canada and at the time was considered the world authority on Cambrian stratigraphy and its fossils. His two volume set “Cambrian Brachiopoda” is a systematic study of the Cambrian fauna of the world. Walcott describes 44 genera, 15 subgenera, 477 species, and 59 varieties of Cambrian Brachiopoda,
