ROSALIND FRANKLIN
Born: London, England, July 25, 1920
Died: London, England, April 16, 1958
Pioneer Molecular Biologist
There is probably no other woman scientist with as much controversy surrounding her life and work as Rosalind Franklin. Franklin was responsible for much of the research and discovery work that led to the understanding of the structure of deoxyribonucleic acid, DNA. The story of DNA is a tale of competition and intrigue, told one way in James Watson's book The Double Helix, and quite another in Anne Sayre's study, Rosalind Franklin and DNA. James Watson, Francis Crick, and Maurice Wilkins received a Nobel Prize for the double-helix model of DNA in 1962, four years after Franklin's death at age 37 from ovarian cancer.

"Franklin was never nominated for a Nobel Prize.[133][134] She had died in 1958 and was therefore ineligible for nomination to the Nobel Prize in 1962 which was subsequently awarded to Crick, Watson, and Wilkins in that year.[9][135][136] The award was for their body of work on nucleic acids and not exclusively for the discovery of the structure of DNA.[137] By the time of the award Wilkins had been working on the structure of DNA for more than 10 years, and had done much to confirm the Watson–Crick model.[138] Crick had been working on the genetic code at Cambridge and Watson had worked on RNA for some years.[139] Watson has suggested that ideally Wilkins and Franklin would have been awarded the Nobel Prize in Chemistry.[8]"

"Unpublished drafts of her papers (written just as she was arranging to leave King's College, London) show that she had independently determined the overall B-form of the DNA helix and the location of the phosphate groups on the outside of the structure. Moreover, it was a report of Franklin's that convinced Crick and Watson that the backbones had to be on the outside,[5] which was crucial since before this both they and Linus Pauling had independently generated non-illuminating models with the chains inside and the bases pointing outwards.[6] However, her work was published third, in the series of three DNA Nature articles, led by the paper of Watson and Crick which only hinted at her contribution to their hypothesis.[7] "
"One of Rosalind Franklin's important contributions to the Crick and Watson model was her lecture at the seminar in November 1951, where she presented to those present, among them Watson, the two forms of the molecule, type A and type B, and her position whereby the phosphate units are located in the external part of the molecule. She also specified the amount of water to be found in the molecule in accordance with other parts of it, data that have considerable importance in terms of the stability of the molecule. Franklin was the first to discover and formulate these facts, which in fact constituted the basis for all later attempts to build a model of the molecule."
"Sayre's early analysis was often ignored because of perceived feminist overtones in her book. It should be noted that in their original paper, Watson and Crick do cite the X-ray diffraction work of both Wilkins and Franklin. In addition, they admit their having "been stimulated by a knowledge of the general nature of the unpublished experimental results and ideas of Dr. M. H. F. Wilkins, Dr. R. E. Franklin and their co-workers at King's College, London."[130] Franklin and Raymond Gosling's own publication in the same issue of Nature was the first publication of this more clarified X-ray image of DNA."
