Linus PAULING
Biography

Linus Pauling was a remarkable American chemist, biochemist, peace activist, author, and educator who made significant contributions to science and society throughout his life. Born on February 28, 1901, in Portland, Oregon, Pauling developed a passion for science at an early age. His father's pharmacy exposed him to the world of chemicals and medicine, laying the foundation for his future career.

Pauling attended Oregon State University, where he earned a degree in chemical engineering in 1922. He then pursued a Ph.D. in chemistry at the California Institute of Technology (Caltech). At Caltech, Pauling's brilliance became evident as he delved into the study of the nature of the chemical bond. In 1931, at the age of 30, he published his groundbreaking book, "The Nature of the Chemical Bond," which laid the groundwork for understanding the structure of complex substances.

One of Pauling's most significant contributions to science was his elucidation of the alpha helix and beta sheet structures of proteins, which earned him the Nobel Prize in Chemistry in 1954. His work in this area paved the way for the field of molecular biology.

During World War II, Pauling applied his scientific expertise to contribute to the war effort. He conducted research on explosives, and his work on the oxygen meter helped improve the safety of pilots flying at high altitudes. His efforts earned him the Presidential Medal for Merit in 1948.

In the post-war years, Pauling turned his attention to social and political issues. He became a vocal advocate for peace and disarmament, a stance that would eventually lead to controversy during the Red Scare era. Pauling's activism, coupled with his association with leftist groups, attracted the attention of anti-communist authorities. His passport was revoked in 1952, limiting his ability to travel and collaborate internationally.

The height of the controversy came during the 1950s when Pauling spoke out against nuclear weapons testing. His efforts culminated in the 1958 petition known as the "Bomb Test Petition," signed by thousands of scientists worldwide, calling for a halt to nuclear weapons testing. Although the petition did not immediately change government policy, it marked a significant moment in the intersection of science and politics.

In 1962, Linus Pauling received the Nobel Peace Prize for his activism against nuclear weapons testing, making him one of the few individuals to receive two unshared Nobel Prizes. Despite facing criticism and challenges to his reputation in the U.S. during this period, Pauling remained committed to his principles.

Later in his career, Pauling focused on the health benefits of vitamin C. His advocacy for high-dose vitamin C supplementation stirred controversy in the scientific community, with some criticizing his claims as exceeding the available evidence. Nevertheless, Pauling continued to promote the health benefits of vitamin C until his death.

Linus Pauling's life was characterized by a relentless pursuit of knowledge, a commitment to social causes, and a passion for peace. His contributions to science and his advocacy for global cooperation left an enduring legacy. Pauling passed away on August 19, 1994, but his impact on the fields of chemistry, peace, and activism continues to be remembered and studied.
