Linus Pauling was one of the most important scientists of the 20th century, and he remains the only person ever to receive two unshared Nobel Prizes: the first was awarded to him for Chemistry (1954) and the other for Peace (1962). He was a man of remarkable talent, who had a vast array of scientific interests, and who always maintained a deep and abiding passion for humankind and its survival. To many, he is best remembered for his strong belief in the importance of vitamin C, despite his numerous other accomplishments. During his lifetime, he produced hundreds of notebooks documenting his various research endeavors and musings on various timely scientific topics. The Linus Pauling Institute at Oregon State University has digitized many of these notebooks and placed them online for the benefit of the public. Visitors may browse the notebooks at their leisure, or go through a selection of highlights, including his first notes on superconductivity and his first notes on vitamin C and the common cold.
