Linus Pauling
Linus Pauling (February 28, 1901-August 19, 1994) was an American physical chemist, biochemist, activist, author, and educator. Pauling was extremely prolific; he published over 1200 papers and books. Winning two Nobel Prizes in 1954 and in 1962, Pauling is the only individual to win two, unshared Nobel Prizes. The first was for his research in chemistry that shed light onto the nature of the chemical bond and its application to elucidation of the structure of complex substances. The second was a Nobel Peace Prize for his efforts to stop the atmospheric testing of nuclear weapons.
