Linus Pauling was an influential American scientist and peace advocate who remains the only person to ever win two unshared Nobel Prizes. He is recognized as a foundational figure in quantum chemistry and molecular biology, having made landmark discoveries regarding the nature of chemical bonds and the structure of proteins. Beyond his laboratory success, Pauling was a dedicated activist who campaigned against nuclear testing and received the Nobel Peace Prize for his efforts toward disarmament. In his later years, he became a controversial figure for his promotion of orthomolecular medicine and the use of high-dose Vitamin C. His extensive legacy is preserved through numerous academic institutions, scientific awards, and his pioneering research into molecular diseases like sickle cell anemia. Overall, these records document a life defined by extraordinary scientific versatility and a profound commitment to global humanitarian issues.
