Linus Pauling (February 28, 1901 – August 19, 1994) was an American quantum chemist and biochemist. Pauling is regarded by many as the premier chemist of the twentieth century, especially for the versatility of his contributions. He pioneered the application of quantum mechanics to chemistry, and in 1954 was awarded the Nobel Prize in chemistry for his work describing the nature of chemical bonds. Pauling received the Nobel Peace Prize in 1962 for his campaign against above-ground nuclear testing. Later in life, he became an advocate for greatly increased consumption of vitamin C and other nutrients. Pauling was born in Oswego, Oregon. In the 1930s he began publishing papers on the nature of the chemical bond, leading to his famous textbook on the subject published in 1939. It is based primarily on his work in this area that he received the Nobel Prize in Chemistry in 1954. In 1958, Pauling and his wife presented the United Nations with a petition signed by more than 11,000 scientists calling for an end to nuclear-weapon testing. Public pressure subsequently led to a moratorium on above-ground nuclear weapons testing, followed by the Partial Test Ban Treaty, signed in 1963 by John F. Kennedy and Nikita Khrushchev. On the day that the treaty went into force, the Nobel Prize Committee awarded Pauling the Nobel Peace Prize.
