Linus Pauling

Linus Carl Pauling (February 28, 1901 – August 19, 1994) was an American quantum chemist and biochemist. He was also acknowledged as a crystallographer, molecular biologist, and medical researcher. Pauling is widely regarded as the premier chemist of the twentieth century. 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. He also made important contributions to crystal and protein structure determination, and was one of the founders of molecular biology. He came near to discovering the "double helix," the ultrastructure of DNA, which Watson and Crick discovered in 1953. Pauling is noted as a versatile scholar for his expertise in inorganic chemistry, organic chemistry, metallurgy, immunology, anesthesiology, psychology, debate, radioactive decay, and the aftermath of nuclear warfare, in addition to quantum mechanics and molecular biology.

Pauling received the Nobel Peace Prize in 1962 for his campaign against above-ground nuclear testing, and is the only person to win two Nobel prizes that were not shared with another recipient. The other people who have received two Nobel prizes are Marie Curie (physics and chemistry), John Bardeen (both in physics) and Frederick Sanger (both in chemistry). Later in life, he became an advocate for greatly increased consumption of vitamin C and other nutrients. He generalized his ideas to define orthomolecular medicine, which is still regarded as unorthodox by conventional medicine. He popularized his concepts, analyses, research and insights in several successful but controversial books centered around vitamin C and orthomolecular medicine.
