LINUS PAULING (1901-1994) was the only winner of two unshared Nobel Prizes. He won the Nobel Prize in Chemistry in 1954 for his research on the nature of the chemical bond holding molecules together and its use in understanding the structure of complex substances such as protein and antibodies. After the development of the atomic bomb, Pauling campaigned against nuclear weapons. He won the 1962 Nobel Peace Prize for his efforts. WILLIAM B. SHOCKLEY (1910-1989), John Bardeen and Walter Brattain were awarded the 1956 Nobel Prize for Physics "for their researches on semiconductors and their discovery of the transistor effect" while at Bell Laboratories. Shockley, a London-born American physicist, was equally famous for two statements. Based on his research, he had publicly proclaimed that Blacks were "genetically inferior", and he had proposed creating a sperm bank in which sperm from Nobel Laureates would be preserved to inseminate intelligent women to create exceptionally bright children. Nuclear chemist GLENN THEODORE SEABORG (1912-1999) and Edwin M. McMillan won the 1951 Nobel Prize in Chemistry "for their discoveries in the chemistry of the transuranium elements". Seaborg is best known for his work in the synthetic transuranium elements. He was responsible for the discovery of ten elements: americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, plutonium and seaborgium. When "seaborgium" was officially accepted as the name for element 106 in August 1997, it marked the first time an element had ever been named for a living person. Slightly rippled. Fine condition.
