The National Library of Medicine presents the Fred L. Soper Papers, a new Profiles in Science feature. The collection includes a selection of digitized documents available for use by educators and researchers. First-time visitors may wish to begin with the online exhibit -- a well-presented introduction to the scientific career and professional life of Soper, an American epidemiologist and public health administrator who "set new standards for disease control worldwide." Users may also search the site for specific documents and visuals, or easily browse the entire collection listed alphabetically or chronologically.
