He was a high school drop-out, a maverick who jumped disciplinary fences, and an activist who was attacked for his political beliefs. Yet he won two Nobel prizes and published more than 500 papers and 11 books. His name was Linus Carl Pauling (1901-1994) and he is probably one of the few scientists to be a household name. Linus Pauling is the eighth scientist to be added to the National Library of Medicine’s (NLM) Profiles in Science Web site (http://profiles.nlm.nih.gov/). He remains the only person in history to win two unshared Nobel Prizes. “Linus Pauling revolutionized the study of chemistry, and made crucial contributions to medical research,” said Dr. Alexa McCray, who heads up the Profiles project.
