<P> Frederick Sanger OM CH CBE FAA ( / ˈsæŋər / ; 13 August 1918 -- 19 November 2013 ) was a British biochemist who twice won the Nobel Prize in Chemistry , one of only two people to have done so in the same category ( the other is John Bardeen in physics ) , the fourth person over all with two Nobel Prizes , and the third person over all with two Nobel Prizes in the sciences . In 1958 , he was awarded a Nobel Prize in chemistry `` for his work on the structure of proteins , especially that of insulin '' . In 1980 , Walter Gilbert and Sanger shared half of the chemistry prize `` for their contributions concerning the determination of base sequences in nucleic acids '' . The other half was awarded to Paul Berg `` for his fundamental studies of the biochemistry of nucleic acids , with particular regard to recombinant DNA '' . </P>
