X-ray crystallography of biological molecules took off with Dorothy Crowfoot Hodgkin, who solved the structures of cholesterol (1937), penicillin (1946) and vitamin B 12 (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 years.

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.
2005 - The first X-ray free-electron laser in the soft X-ray regime, FLASH, became an operational user facility at DESY for X-ray diffraction experiments. [ 252 ] 2007 - Ute Kolb and co-workers developed automated diffraction tomography for electron crystallography by combining diffraction and tomography within a transmission electron microscope .
Firstly they showed that X-ray crystallography could be used to reveal the regular, ordered structure of DNA – an insight which laid the foundations for the later work of Maurice Wilkins and Rosalind Franklin, [1] after which the structure of DNA was identified by Francis Crick and James D. Watson in 1953. Secondly, they did this work at a ...
Portrait of William Lawrence Bragg taken when he was around 40 years old. Sir William Lawrence Bragg (31 March 1890 – 1 July 1971), known as Lawrence Bragg, was an Australian-born British physicist and X-ray crystallographer, discoverer (1912) of Bragg's law of X-ray diffraction, which is basic for the determination of crystal structure.
Crick was in the right place, in the right frame of mind, at the right time (1949), to join Max Perutz's project at the University of Cambridge, and he began to work on the X-ray crystallography of proteins. [30] X-ray crystallography theoretically offered the opportunity to reveal the molecular structure of large molecules like proteins and ...
Photo 51 is an X-ray based fiber diffraction image of a paracrystalline gel composed of DNA fiber [1] taken by Raymond Gosling, [2] [3] a postgraduate student working under the supervision of Maurice Wilkins and Rosalind Franklin at King's College London, while working in Sir John Randall's group.
