Linus Carl Pauling was an American chemist whose account of the chemical bond reshaped twentieth-century science, and whose campaign against nuclear weapons made him one of the most visible scientists of the atomic age. He remains the only person to have won two unshared Nobel Prizes: the 1954 Nobel Prize in Chemistry and the 1962 Nobel Peace Prize.
Pauling was born in Portland, Oregon, on 28 February 1901. His father, Herman, was a druggist who died in 1910, leaving the family short of money when Linus was nine. As a boy he ran chemistry experiments at home and read constantly. He entered Oregon Agricultural College, now Oregon State University, at the age of sixteen and earned a degree in chemical engineering in 1922. He then moved to the California Institute of Technology, where he completed a PhD in chemistry in 1925 and used X-ray diffraction to work out the structure of crystals, the method that anchored much of his later research (Wikipedia).
Through the late 1920s and 1930s Pauling applied the new quantum mechanics to chemistry, developing the ideas of orbital hybridization, resonance, and a practical scale of electronegativity that let chemists predict how atoms share electrons. He gathered this thinking into The Nature of the Chemical Bond (1939), a book often called the most influential chemistry text of the century. He then extended structural methods to biology, proposing the alpha helix as a basic shape of proteins in 1951 with Robert Corey and Herman Branson, and in 1949 showing that sickle-cell anemia arises from a defect in the hemoglobin molecule, which he named a molecular disease. For this body of work he received the 1954 Nobel Prize in Chemistry, cited for research into the nature of the chemical bond.
After the Second World War Pauling turned to public life. Alarmed by radioactive fallout, he campaigned against atmospheric nuclear testing, presented a petition signed by thousands of scientists to the United Nations in 1958, and argued the case in speeches and in his book No More War! that same year. His efforts helped build support for the Partial Test Ban Treaty, which took effect on 10 October 1963. On that same day the Norwegian Nobel Committee announced that Pauling would receive the reserved 1962 Nobel Peace Prize, making him the only person to hold two Nobel Prizes that he did not share with anyone. The recognition came despite years of political suspicion during the McCarthy era, when his passport was withheld.
Pauling's structural chemistry became part of how the subject is taught, and his protein work fed directly into the birth of molecular biology. Francis Crick, who with James Watson described the DNA double helix in 1953, regarded Pauling as one of the founders of the field, since Pauling's model-building approach shaped the race to solve the structure of DNA (Wikipedia).
His final decades are harder to summarize. From 1970 Pauling promoted large doses of vitamin C, first for the common cold in his book Vitamin C and the Common Cold, and later, with the surgeon Ewan Cameron, as a treatment for cancer. He called this approach orthomolecular medicine. Controlled trials at the Mayo Clinic failed to confirm the cancer claims, and most physicians and nutrition researchers rejected the strongest of his assertions (Wikipedia). The episode shows how a scientist of great standing could hold views the evidence did not support, and it sits alongside his genuine achievements rather than erasing them.
Honors and institutions carry his name. The Linus Pauling Institute, now at Oregon State University, holds his papers and studies nutrition and health, and the Linus Pauling Science Center opened there in 2011. Pauling died of prostate cancer at his ranch at Big Sur, California, on 19 August 1994.
We keep Pauling because his record holds both brilliance and error in the same life, which is how real careers usually look. His two Nobel Prizes and his contested later theories belong to one story worth remembering accurately.
