Designed to document American scientist Linus Pauling's role in the early 1950s race to discover the structure of DNA, this site contains more than 800 primary sources. Some 650 documents and photographs provide an unusually frank glimpse into Pauling's life; much of the correspondence in the collection is between Pauling and other front runners in the race (Watson and Crick, for example, and Rosalind Franklin). In addition to the documents and photographs, the site includes 16 of Pauling's published papers, 15 unpublished manuscripts and notebooks, and 22 audio and video clips of Pauling. There is a thorough chronology, which details the personal and professional dimensions of Pauling's life, including his troubles with the State Department and their refusal to issue him a passport on the basis of national security. Professional rivalries and personal jealousies, as well as victories and triumphs, are all documented in correspondence and in video interviews.

Although Pauling lost the DNA race, he was eventually awarded two Nobel Prizes. In addition to a typical search feature, Linus Pauling Day-By-Day allows viewers to learn about events and to examine selected correspondence relevant to any given day, from January 1952 through December 1953.

These materials come from a museum with approximately 4,000 pieces of racist memorabilia donated from Pilgrim's personal collection.

More than 40 historical census reports, including decennial reports dating back to 1790, are available for download on this website as PDFs.
