Dorothy Mary Crowfoot Hodgkin OM FRS HonFRSC [9] [10] (née Crowfoot; 12 May 1910 – 29 July 1994) was a Nobel Prize-winning English chemist who advanced the technique of X-ray crystallography to determine the structure of biomolecules, which became essential for structural biology.
1937 onwards: Protein crystallography developed by Dorothy Crowfoot Hodgkin (1910–1994); Hodgkin solved the structures of cholesterol (1937), penicillin (1946), and vitamin B12 (1956), for which she was awarded the Nobel Prize in Chemistry in 1964; in 1969, she succeeded in solving the structure of insulin, on which she worked for over thirty ...
Molecular model of penicillin by Dorothy Hodgkin, 1945. In 1932 Dorothy Hodgkin joined the laboratory of the physicist John Desmond Bernal, who was a former student of Bragg, in Cambridge, UK. She and Bernal took the first X-ray photographs of crystalline proteins. Hodgkin also played a role in the foundation of the International Union of ...
John Hodgkin (1766–1845) [1] John Hodgkin (1766–1845) was an English tutor, grammarian, and calligrapher. He married Elizabeth Rickman (1768-1833) of a Sussex Quaker family and together they had four sons of whom the first two died in infancy [2]

The following is a list and timeline of innovations as well as inventions and discoveries that involved British people or the United Kingdom including the predecessor states before the Treaty of Union in 1707, the Kingdom of England and the Kingdom of Scotland.
Dorothy Hodgkin determined the correct chemical structure of penicillin using X-ray crystallography at Oxford in 1945. [ 168 ] [ 169 ] In 1945, the US Committee on Medical Research and the British Medical Research Council jointly published in Science a chemical analyses done at different universities, pharmaceutical companies and government ...
Dorothy Hodgkin won the prize in 1964 for the development of protein crystallography. Among her significant discoveries are the structures of penicillin and vitamin B12. Forty five years later, Ada Yonath shared the prize with Venkatraman Ramakrishnan and Thomas A. Steitz for the study of the structure and function of the ribosome.
1969 – Dorothy Crowfoot Hodgkin deciphered the three-dimensional structure of insulin. 1970 – Hamilton Smith and Daniel Nathans discovered DNA restriction enzymes. 1970 – Howard Temin and David Baltimore independently discovered reverse transcriptase enzymes. 1972 – Albert Eschenmoser and Robert Woodward synthesized vitamin B 12.
