British biochemist. He won a 1958 Nobel Prize for determining the order of amino acids in the insulin molecule and shared a 1980 Nobel Prize for developing methods for mapping DNA structure and function.
American nurse who campaigned widely for birth control and founded (1929) the organization that became the Planned Parenthood Federation (1942).
British biochemist who determined the order of amino acids in the insulin molecule, thereby making it possible to manufacture synthetic insulin. For this work, he received the Nobel Prize for chemistry in 1958. In 1980 Sanger received another Nobel Prize for chemistry (jointly with American molecular biologists Paul Berg and Walter Gilbert) for his development of methods for mapping the structure and function of DNA.
