Charles Doolittle Walcott

The fourth Secretary of the Smithsonian, Charles Doolittle Walcott, was a paleontologist noted for his discovery of the Burgess Shale fossils in Canada in the early twentieth century. Largely self-educated, Walcott worked for the New York State Museum and US Geological Survey (USGS), and advanced to become the USGS director from 1894 to 1907. He then served as Secretary of the Smithsonian until his death in 1927. Walcott was also a member of a variety of scientific and government boards and commissions, playing a central role in American science policy.
