Linus Carl Pauling

Historical

Feb 28, 1901

Aug 19, 1994

Linus Carl Pauling was an American chemist, biochemist, and peace activist who significantly contributed to modern chemistry and molecular biology. He was born in Portland, Oregon, and came from a family of a druggist. He had an early interest in science and started doing experiments. He did very well in his early years of learning and got admitted to Oregon Agricultural College (now Oregon State University), where he developed an interest in chemical bonds. He then went on to attend the California Institute of Technology, where he obtained his Ph.D. in 1925, with his research interest being in crystallography, where he did his early work that paved the way for his contributions to molecular science. Pauling produced a lot of scientific work in his lifetime. His work in quantum chemistry and molecular biology helped change how the chemical bond was viewed. In 1939, he came out with the book The Nature of the Chemical Bond, which is said to be one of the twentieth century's most essential books in chemistry. He also put forward some important ideas, like the concept of orbital hybridization and electronegativity, which are crucial in today’s chemistry. His work on the structure of proteins, particularly the alpha helix, was instrumental in developing molecular biology and understanding DNA. He was awarded the Nobel Prize in Chemistry in 1954 for his contribution. However, besides his scientific achievements, Pauling was also an active peace advocate. In the course of the Cold War, he was an advocate of nuclear disarmament and wrote articles and delivered speeches against nuclear testing. His persistent efforts culminated in the Partial Nuclear Test Ban Treaty in 1963. For his activism, Pauling was awarded the Nobel Peace Prize in 1962 and thus became the only person to receive two unshared Nobel Prizes. He received political backlash during the Red Scare but never wavered in his commitment to science and peace. In his later years, Pauling concentrated on health and medicine, especially administering high doses of Vitamin C to prevent diseases, including cancer. Despite the controversy, his work in orthomolecular medicine gained the interest of people who believed in his theories and those who doubted them. Pauling’s later works did not diminish his fame; he remained one of the most famous scientists of the twentieth century. He passed on in 1994 due to prostate cancer, but his contributions to chemistry, molecular biology, and peace activism are still felt.

Life and achievements

Early life

Linus Carl Pauling was born in Portland, Oregon, on February 28, 1901. His father was a pharmacist named Herman Pauling, and his mother was Belle Darling Pauling, a homemaker. Linus Pauling’s father died in 1910 when Linus was only nine years old, which made him have to work to support his mother and siblings, thus making him a very independent person. Pauling’s interest in science started when he was a child, and he constructed his first chemistry laboratory in the basement of his house. In his childhood, he performed chemical experiments that he could either get or prepare from other sources, which showed his interest in science. Pauling was a bright student in his academic pursuits, which was seen in his early years of learning. He did his first three years of high school at Washington High School but dropped out and did not graduate, finding many of his classes uninteresting and unrelated to his interests. He joined Oregon Agricultural College when he was 16 years old. It was here that his love for chemistry was well nurtured. Influenced by the teachers, he continued his passion for molecular structures and chemical bonds, which formed the basis of his future research. Pauling completed his BSc in 1922 and then proceeded to do his Ph.D. at the California Institute of Technology, which he would attend for most of his academic career. His doctoral thesis was on the crystallographic studies of crystals by X-ray diffraction, which can be considered a precursor to his future work in molecular biology and quantum chemistry.

Legacy

The contributions of Linus Pauling in science, medicine, and social activism are still felt to this day. As a quantum chemist, molecular biologist, and a leading figure promoting the culture of peace in the twentieth century, Pauling is one of the most famous scientists. His research on the chemical bond is considered one of the most influential works in chemistry and is still used in the current curriculum. Pauling’s work on the protein structures, such as the alpha-helix, helped identify the DNA double helix by James Watson and Francis Crick. As Francis Crick himself admitted, Pauling was the ‘father of molecular biology’ because he was one of the first to understand the concept of molecular structures. Pauling was an outstanding scientist who paid much attention to humanitarian issues. He was a staunch supporter of the disarmament of nuclear weapons and fought for the ban of atmospheric nuclear tests in the middle of the Cold War. His efforts in the fight against atomic fallout earned him the Nobel Peace Prize in 1962. This, together with his Nobel Prize in Chemistry in 1954, made Pauling the only man to have both unshared Nobel Prizes. Pauling’s political activism came under scrutiny during the McCarthy era. Still, he did not waver, and his efforts towards promoting peace have been a source of inspiration to many peace activists. His further research on orthomolecular medicine, including his somewhat questionable theories about the positive effects of large doses of vitamin C, is still a subject of discussion. Although many of his ideas were considered heresies by the members of the medical profession, Pauling’s ideas about health and nutrition are still being investigated regarding the use of vitamins in the prevention and cure of diseases. His work was published as a book titled Vitamin C and the Common Cold, which made people aware of his research in nutritional science. The legacy of Pauling is further continued by the institutions and honours named in his honour. The Linus Pauling Institute at Oregon State University, home to his papers, is still conducting research in nutrition and health. The Linus Pauling Science Center at Oregon State University, constructed in 2011 to focus on chemistry and health research, is a testament to his contribution to society through his research. Pauling’s impact, however, is not limited to science and health, as he was also a man of principles who believed in applying science for the good of society.
