Linus Pauling

Linus Carl Pauling (February 28, 1901 – August 19, 1994) was an American chemist, peace activist, educator, and author who became one of the most influential scientists of the twentieth century. Pauling made groundbreaking contributions to chemistry, particularly in understanding chemical bonding, molecular structure, and chemical reactivity. In 1954, he was awarded the Nobel Prize in Chemistry for his research into chemical bonds and their application to the elucidation of complex molecular structures. Beyond chemistry, Pauling was a passionate advocate for nuclear disarmament and world peace, particularly during the Cold War era. His activism earned him the Nobel Peace Prize in 1962, making him one of only four individuals to win Nobel Prizes in more than one category. Later in life, Pauling became interested in orthomolecular psychiatry and the use of vitamins, particularly vitamin C, in treating various illnesses—work that was both celebrated and controversial. His legacy encompasses his scientific achievements in understanding molecular chemistry, his advocacy for peace, and his influence on how scientists engage with public discourse and social responsibility. Pauling remains an exemplar of the scientist as both researcher and global citizen.
