چکیده انگلیسی
Famously, James Watson credited the discovery of the double-helical structure of DNA in 1953 to an X-ray diffraction photograph taken by Rosalind Franklin. Historians of molecular biology have long puzzled over a remarkably similar photograph taken two years earlier by the physicist and pioneer of protein structure William T. Astbury. They have suggested that Astbury's failure to capitalize on the photograph to solve DNA's structure was due either to his being too much of a physicist, with too little interest in or knowledge of biology, or to his being misled by an erroneous theoretical model of the gene. Drawing on previously unpublished archival sources, this paper offers a new analysis of Astbury's relationship to the problem of DNA's structure, emphasizing a previously overlooked element in Astbury's thinking: his concept of biological specificity.
