Charles Doolittle Walcott était un paléontologue réputé pour sa découverte des fossiles de Burgess Shale au Canada au début du XXe siècle. Largement autodidacte, Walcott a progressé dans sa carrière grâce à des postes au New York State Museum et au United States Geological Survey (USGS), devenant finalement directeur de l'USGS. Il a joué un rôle déterminant dans l'élaboration de la politique scientifique américaine par sa participation à de nombreux comités scientifiques et gouvernementaux. Ses découvertes ont considérablement fait progresser notre compréhension de la vie primitive sur Terre.
