Presented in February by the National Library of Medicine, the latest Profiles in Science highlights the achievements made by the chemist Linus Pauling. Pauling won the 1954 Nobel Prize in Chemistry "for his research into the nature of the chemical bond and its application to the elucidation of the structure of complex substances. He also won the 1962 Nobel Peace Prize, making him the only person to win two unshared Nobel prizes." The site offers visitors a look at a portion of the Linus Pauling Papers that are held at the Oregon State University Libraries in Corvallis and contain a collection of personal and scientific works digitized for online view. The site can be browsed by the online exhibit (which includes a biographical section), alphabetically or chronologically by work, and can be searched by keyword. This impressive collection gives anyone interested in chemistry a chance to learn more about one of the most influential scientists in the field.
