Linus Carl Pauling
(
/ˈpɔːlɪŋ/
; February 28, 1901 – August 19, 1994) was an American
chemist
,
biochemist
,
chemical engineer
,
peace activist
, author, and educator. He published more than 1,200 papers and books, of which about 850 dealt with scientific topics.
New Scientist
called him one of the 20 greatest scientists of all time, and as of 2000, he was rated the 16th most important scientist in history. For his scientific work, Pauling was awarded the
Nobel Prize in Chemistry
in 1954. For his peace activism, he was awarded the
Nobel Peace Prize
in 1962. He is one of four individuals to have won more than one Nobel Prize (the others being
Marie Curie
,
John Bardeen
and
Frederick Sanger
). Of these, he is the only person to have been awarded two unshared Nobel Prizes, and one of two people to be awarded Nobel Prizes in different fields, the other being
Marie Curie
. He was married to the American human rights activist
Ava Helen Pauling
. Pauling was one of the founders of the fields of
quantum chemistry
and
molecular biology
. His contributions to the theory of the chemical bond include the concept of
orbital hybridisation
and the first accurate scale of
electronegativities
of the elements. Pauling also worked on the structures of biological molecules, and showed the importance of the
alpha helix
and
beta sheet
in
protein secondary structure
. Pauling's approach combined methods and results from
X-ray crystallography
,
molecular model
building, and
quantum chemistry
. His discoveries inspired the work of
James Watson
,
Francis Crick
,
Maurice Wilkins
and
Rosalind Franklin
on the structure of DNA, which in turn made it possible for geneticists to crack the DNA code of all organisms.
In his later years he promoted
nuclear disarmament
, as well as
orthomolecular medicine
,
megavitamin therapy
and
dietary supplements
. None of the latter have gained much acceptance in the mainstream scientific
