Pauling spends a month at the Institute for theoretical physics in Copenhagen with Niels Bohr.

Linus Pauling receives the Nobel Prize for Peace in 1962 "for his campaign against nuclear weapons testing". The ceremony is held in the Auditorium of the University of Oslo, 10 December 1963. Pauling becomes the first person to receive two unshared Nobel awards. Pauling is also one of only two people to be awarded Nobel Prizes in different fields, the other being Marie Curie.

Linus Pauling dies of prostate cancer at his home in Big Sur, California.

Linus Pauling establishes the Institute of Orthomolecular Medicine and becomes his president.

Linus Pauling is named Chairman of the Department of Chemistry and Chemical Engineering at Caltech. His interest focuses increasingly on the new field of molecular biology, biochemistry, the study of enzymes and viruses, and research into blood molecules. In collaboration with his young assistant Robert Corey, he uses X-ray crystallography and successfully discovers the structure of the simplest amino acid, glycine.

Pauling spends six month at the University of Zurich to study under E. Schrödinger.

Linus Pauling is born in Portland, Oregon, first-born child of Herman H.W. Pauling, a pharmacist and Lucy Isabelle "Belle" Darling, a pharmacist’s daughter.

Linus Pauling receives the Nobel Prize for Chemistry "for his research into the nature of the chemical bond and its application to the elucidation of the structure of complex substances."

Linus Pauling enters the California Institute of Technology. Here Roscoe G. Dickinson teaches him how to determine the structures of crystals using X rays. At Caltech, Pauling receives his Ph.D. in physical chemistry and mathematical physics summa cum laude with the dissertation “The Determination with X-Rays of the Structure of Crystals.” From 1925 to 1926 he receives a National Research Council fellowship.

Pauling is Assistant Professor of theoretical chemistry at Caltech. He develops his own method, using wave mechanics to clarify data about molecular structure from X-ray crystallography and vice versa. In the 1930s, his work on the nature of the chemical bond leads him to formulate the concepts of hybridisation, resonance, and electronegativity. In 1939, he publishes the outcomes of more than ten years of research in “The Nature of the Chemical Bond and the Structure of Molecules and Crystals.”

During World War II, Pauling determines an artificial substitute for blood serum and creates an oxygen detector that finds wide use in submarines and airplanes. He explores also explosives, rocket propellants and inks for secret writing.

Linus Pauling is appointed Professor of chemistry at Stanford University, becoming in 1974 professor Emeritus.

During a Visiting Professorship at the University of Oxford, Pauling returns on the study of the three-dimensional structure of proteins. By folding a paper on which he had drawn a chain of linked amino acids, he discovers a cylindrical coil-like configuration, the alpha helix. The most significant aspect of this structure is its determination of the number of amino acids per turn of the helix. With this discovery he foreshadows Crick, Watson, and Wilkins' 1953 discovery of the double-helix.

Linus Pauling attends Washington High School in Portland. Because of a technicality he will not receive his diploma until 1962.

Linus Pauling works as Professor of chemistry at the University of California at San Diego.

Linus Pauling works as Research Professor at Center for the Study of Democratic Institutions. In 1966, Pauling begins to explore the possible effects of vitamin C in preventing colds. His studies are summarized in the 1970 book “Vitamin C and The Common Cold”.

Linus Pauling attends Oregon Agricultural College (later Oregon State University). Here he receives his Bachelor of Science degree in chemical engineering summa cum laude. During those college's years he deepens his interest in chemical bond and molecular structure. Noticing Pauling’s high skills, the professors invite him to teach to freshman-and sophomore-level chemistry courses while he is still a student.

Pauling receives a Guggenheim Foundation fellowship to study quantum mechanics. He ends up spending a year at Arnold Sommerfeld’s Institute for Theoretical Physics in Munich, a month in Copenhagen with Niels Bohr, and six months in Zürich with Erwin Schrödinger. In Munich, he learns the theoretical technique for calculating the size and shape of an atom becoming the only chemist to hold a first rank place among the scientists who apply quantum mechanics to the molecule in the interwar era.
