Rosalind Franklin
British X-ray crystallographer (1920–1958)
This article is about the chemist. For the Mars rover named after her, see Rosalind Franklin (rover).
Rosalind Elsie Franklin (25 July 1920 – 16 April 1958)[1] was a British chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite.[2] Although her works on coal and viruses were appreciated in her lifetime, Franklin's contributions to the discovery of the structure of DNA were largely unrecognised during her life, for which Franklin has been variously referred to as the "wronged heroine",[3] the "dark lady of DNA",[4] the "forgotten heroine",[5] a "feminist icon",[6] and the "Sylvia Plath of molecular biology".[7]
Franklin graduated in 1941 with a degree in natural sciences from Newnham College, Cambridge, and then enrolled for a PhD in physical chemistry under Ronald George Wreyford Norrish, the 1920 Chair of Physical Chemistry at the University of Cambridge. Disappointed by Norrish's lack of enthusiasm,[8] she took up a research position under the British Coal Utilisation Research As

A crucial contribution. Rosalind Franklin made a crucial contribution to the discovery of the double helix structure of DNA, but some would say she got a raw deal. Biographer Brenda Maddox called her the "Dark Lady of DNA," based on a once disparaging reference to Franklin by one of her coworkers. Unfortunately, this negative appellation undermined the positive impact of her discovery. Indeed, Franklin is in the shadows of science history, for while her work on DNA was crucial to the discovery of its structure, her contribution to that landmark discovery is little known.
Her education. Franklin was born on July 25, 1920, in London, to a wealthy Jewish family who valued education and public service. At age 18, she enrolled in Newnham Women's College at Cambridge University, where she studied physics and chemistry. After Cambridge she went to work for the British Coal Utilization Research Association where her work on the porosity of coal became her Ph.D. thesis, and later it would allow her to travel the world as an guest speaker.
In 1946, Franklin moved to Paris where she perfected her skills in X-ray crystallography, which would become her life's work. Although she loved the freedom and lifestyle of Paris, she returned after four years to London to accept a job at K
