Welcome to the National Library of Medicine's Profiles in Science site!
This site celebrates twentieth-century leaders in biomedical research and public health. It makes the archival collections of prominent scientists, physicians, and others who have advanced the scientific enterprise available to the public through modern digital technology.
This new digital database has posted online the complete collection o manuscripts belonging to American biologists Marshall Nirenberg, Christian Anfinsen, Julius Axelrod, Martin Rodbell, Joshua Lederberg, and Oswald T. Avery. The site includes a brief self description and a useful engine that searches the entire digital archive. Researchers who do not find what they are looking for the first time through, may want to return again later as the National Library of Medicine continues to digitize and update its collections.
