(born Aug. 13, 1918, Rendcombe, Gloucestershire, Eng.) British biochemist. Educated at the University of Cambridge, he thereafter worked principally at the Medical Research Council in Cambridge (1951–83).
He spent 10 years elucidating the structure of the insulin molecule, determining the exact order of all its amino acids by 1955. His techniques for determining the order in which amino acids are linked in proteins made it possible to discover the structure of many other complex proteins. In 1958 he won a Nobel Prize for his work. In 1980 Sanger became the fourth person ever to be awarded a second Nobel Prize, which he shared with Paul Berg and Walter Gilbert (b. 1932), for determining the sequences of nucleotides in the DNA molecule of a small virus.
