The Paulings in Latin America, 1940s – 1950s

La Prensa, (Mexico City) September 6, 1949.

[Part 1 of 5]

Throughout his long career as a scientist and peace advocate, Linus Pauling’s work took him all over the world, not excluding Latin America, to which he traveled multiple times. In fact, of the nineteen countries which today constitute Latin America, the only ones which Pauling did not visit were Ecuador, Honduras, Paraguay and Uruguay.

During his trips to the southern hemisphere he typically gave speeches on familiar topics including hemoglobin, the architecture of molecules, orthomolecular medicine, nuclear weapons and, of course, vitamin C. He also frequently advocated for human rights, speaking out against the incarceration of intellectuals in Argentina in the 1960s, urging the leaders of Latin America to resist the acquisition of nuclear weapons, and stressing the necessity for world peace and cooperation. Along the way, Pauling also received many awards, including membership in the Chilean Chemistry Society, the National Medal of the Chilean Senate and honorary citizenship of Puerto Rico.

In September 1949, on one of his earliest trips to Latin America, Pauling traveled to Mexico City to attend the Western Continental Congress for Peace. At the conference, Pauling delivered an address as the United States delegate, as well as a second speech titled, “Man – An Irrational Animal.”

In his delegate’s address, Pauling pointed out that the purpose of the conference was to work towards “permanent, world-wide peace” as well as to foster more effective cooperation between the people of the Americas. From his perspective as a scientist, Pauling felt that he could see order everywhere in the natural world, except for the seeming self-destructiveness of the human race. Pauling felt that the fight for peace included the fight for human rights, and that it was every individual’s responsibility to contribute. However, he believed that scientists should play a special role, suggesting that “the world looks to science for the ultimate solution of the threatening natural problems that menace it.”

At the Mexico City conference, Pauling also argued that scientists needed more freedom in order to focus their energy on solving problems such as world hunger, rather than on the preparation for and conducting of war. He likewise stressed that the United Nations needed to be more powerful, so that it could not be dominated by one or two great powers. To do this, Pauling rationalized, participating nations should transfer part of their sovereignty to the UN in order to form a democratic world government. At the end of the address, Pauling again stressed that world peace must be a democratic and collective undertaking, proclaiming that

It is we, the people, who now have the duty of working for peace, for the welfare and happiness of human beings everywhere. If another devastating world war comes, it will be because we, the people of the world, have failed. We must not fail.

On the same day that he delivered his address as a delegate, Pauling also gave a second speech “Man – An Irrational Animal.” In this talk, he reiterated his “deep interest in the structure of the material world,” and appreciation of the harmony and the workings of nature, but again suggested that the world of man was an anomaly to nature’s pattern of balance and structure. Pauling lamented that “we see groups of men, who make up the nations of the world, devoting the material wealth of the world and the intellectual powers of man, the ‘rational’ animal, not for the welfare of mankind, but for destruction.”

He attributed most of the problems that existed during the time to the struggle between the Soviet Union and the United States, pointing out that nearly ten percent of the world’s income was being used for war or preparation for war. He also stressed that, in the U. S., the fear of communism or any form of liberal thought was prohibiting many scientists from finding work in universities and the private sector alike. Pauling’s solution to the problems of the era was to propose that more funds be channeled toward UNESCO’s peace efforts, and that less be spent on war.

Pauling’s participation in the Mexico City assembly managed to rankle both the U. S. government as well as his fellow delegates.  As it turns out, unbeknownst to Pauling, the Western Continental Congress for Peace was  a Communist-organized gathering, and was accurately criticized as such back home.  In biographer Thomas Hager‘s words,

…that, of course, did not bother the Paulings.  They loved Mexico City – Ava Helen was becoming an admirer of folk art from around the world and spent time combing the mercados for pieces to add to her collection – but were less enthusiastic about the meeting, which seemed to consist of speech after long-winded speech defending the Soviet Union and attacking the United States.  His keynote address ranged from standard socialist anti-imperialism…to a purposeful and carefully evenhanded denouncement of both the United States’ and USSR’s policies of curtailing freedom and preparing for war.  The audience, expecting another one-sided attack on the Yankees, responded with lukewarm applause.

Pauling’s next visit to Latin America came about in May 1955, when Linus and Ava Helen were invited to a conference at the University of Puerto Rico by the Chancellor of the University, Jaime Benitez. At the meeting, Pauling gave three speeches: “The Hemoglobin Molecule in Health and Disease,” “The Structure of Proteins,” and “Technology and Democracy.”

In “Technology and Democracy” – of the three, the only talk that he did not give on a regular basis to many other groups – Pauling commented that it was impossible for people to consider themselves “cultured” if they did not know about the sciences as well as about the rest of the world. He argued that “non-scientists, too, should be people of culture who have an understanding of the world, and this they cannot be without a knowledge of science.” Pauling also urged that more science be included in the curricula of elementary schools, and at a more advanced level. Pauling felt that people should be more interested in science because “knowledge of the nature of the world in which we live contributes to our happiness.”

Pauling’s trips to Mexico and Puerto Rico were just the beginning of an extensive political and scientific relationship that he maintained with Latin America.  In the coming weeks, we will take a closer look at several of his Ava Helen’s many visits to countries south of the border, from the 1960s through the 1980s.
