Sanger, Frederick (1918–)
British biochemist awarded the 1958 Nobel Prize in Chemistry
for his work on proteins, particularly for
first determining the complete structure of a protein, that of bovine insulin.
In 1980 he became the fourth person to receive two Nobel prizes (and the
first to win the Chemistry prize twice) when he was again awarded the Nobel
Prize in Chemistry, jointly with Paul Berg and Walter Gilbert, for their
work on the chemistry of nucleic acids.
Sanger and his colleagues found the entire sequence of the more than 5,400
bases in the DNA of a virus and some 17,000
bases of another DNA. Sanger's contribution was to refine the techniques
for determining the structure of more complex proteins.
