Rosalind Franklin was an English chemist and X-ray crystallographer whose photographs of DNA fibres, above all the image known as Photo 51, supplied measurements that were central to the 1953 model of the double helix. She also did lasting work on the structure of coal and of viruses. She died in 1958 at the age of 37, four years before the Nobel Prize was awarded for the discovery her data had helped make possible.
Rosalind Elsie Franklin was born on 25 July 1920 in Notting Hill, London, into a prosperous and well-connected Anglo-Jewish family; her father, Ellis Franklin, was a merchant banker who also taught at a college for working men (Wikipedia). She attended St Paul's Girls' School in Hammersmith, one of the few London schools that taught physics and chemistry to girls, and decided early that she wanted to be a scientist. In 1938 she entered Newnham College, Cambridge, and graduated in natural sciences in 1941.
From 1942 she worked for the British Coal Utilisation Research Association, studying the microstructure of coal and charcoal. That research earned her a Cambridge PhD in 1945 and showed how the tiny pores in coal relate to its density and behaviour, findings still cited in carbon science. From 1947 to 1950 she worked in Paris at a state chemistry laboratory, where she learned X-ray diffraction under the crystallographer Jacques Mering and became expert at applying it to disordered, non-crystalline materials (Britannica).
In 1951 Franklin joined King's College London to apply X-ray methods to DNA. Working with the PhD student Raymond Gosling, she distinguished two forms of the molecule, the wet B form and the dry A form, and in May 1952 she recorded Photo 51, a diffraction image of the B form whose cross-shaped pattern pointed clearly to a helix (Science News). Her careful measurements fixed key dimensions and supported the conclusion that the sugar-phosphate backbones lie on the outside of the molecule.
Franklin's working relationship with her colleague Maurice Wilkins was strained, and in early 1953 her results reached the Cambridge team of James Watson and Francis Crick without her knowledge. Wilkins showed Watson a copy of Photo 51, and an internal Medical Research Council report containing her unpublished numerical data was passed to Crick. Those data helped Watson and Crick build the correct model, published in Nature on 25 April 1953. Franklin's own paper, written with Gosling, appeared in the same issue.
Later in 1953 she moved to Birkbeck College and turned to viruses. Her group, which included the future Nobel laureate Aaron Klug, worked out much of the structure of the tobacco mosaic virus, showing how its RNA is arranged within a protein coat, and she had begun studying poliovirus when she fell ill (Wikipedia).
Franklin was diagnosed with ovarian cancer in 1956 and died on 16 April 1958, aged 37. The 1962 Nobel Prize in Physiology or Medicine went to Crick, Watson and Wilkins for the structure of DNA (NobelPrize.org). The prize is not awarded posthumously, so Franklin could not have shared it; whether she would have been named had she lived remains an open question.
The popular story of Franklin as a wronged genius owes much to Watson's 1968 memoir The Double Helix, which described her dismissively and helped fix the image of a woman denied her due. Historians have since drawn a more accurate picture. A 2023 reassessment in Nature by Matthew Cobb and Nathaniel Comfort argued that Franklin understood DNA was helical and acted as an equal contributor whose data formed part of a wider, if imperfect, scientific exchange, rather than a passive victim whose photograph was simply stolen (Nature; Science News). The real failing was that her role went largely unacknowledged at the time and for years afterwards.
Franklin's page records careful, patient work whose value was recognised slowly, and mostly after her death. We keep it because what a person contributes does not depend on the credit they received while they were alive.
