First Edition. Bernal, one of the pioneers of X-ray crystallography, and his student Dorothy Crowfoot (later Hodgkin) were the first to demonstrate that X-ray photographs of a crystallized protein (the enzyme pepsin) could produce diffraction patterns, thereby providing a key to the protein’s molecular structure. “Bernal and Crowfoot’s observation opened the subject of protein crystallography” (Perutz, Science is not a Quiet Life, p. xviii). Their paper may also mark the beginning of structural molecular biology. 6923.
