Which scholar listed won two Nobel Prizes in two different fields in the mid -1950s and early - 1960s?

Linus Pauling (February 1901 – August 1994), an American chemist, biochemist, chemical engineer, peace activist, author, and educator, is the only person to receive two unshared Nobel Prizes. Only he and Marie Curie have won for two different fields. His discoveries in chemical bonding won him the first in 1954; he then helped found molecular biology as a discipline. His work in this field greatly inspired others in race for the deoxyribonucleic acid (DNA) structure, a molecule that contains the genetic code that is unique to every individual.

He pioneered quantum chemistry and made the extraordinary prediction of the existence of alpha helices and beta sheets – the secondary structures of proteins. If not for basic errors in predicting the DNA structure, he could have won a third prize but that eventually went to the molecular biologists Francis Crick, James Watson and Maurice Wilkins. His mistakes inadvertently helped the scientist Rosalind Franklin find what was missing. Franklin was the unsung hero of DNA's discovery, excluded from the Nobel prize despite her crucial contribution.

His second prize was not one of the science prizes; he won the Nobel Peace Prize in 1962. It was awarded for his passionate advocacy for nuclear disarmament with his wife, and he placed himself in the public eye against nuclear testing of weapons wherever possible. He was awarded every major chemistry prize during his life.
