1 SPOTLIGHT ON Biophysicist, Physical Chemist and Molecular Biologist

2  British chemist Rosalind Franklin is best known for her role in the discovery of the structure of DNA, and for her pioneering use of X-ray diffraction  1945 – Franklin earned a Ph.D. in physical chemistry from Cambridge University  1946 - Franklin went to the Laboratoire Central des Services Chimiques de l'Etat in Paris, she worked with crystallographer Jacques Mering where he taught her X-ray diffraction  1951 – Franklin works as a research associate at King’s College in London. She was to be the only experienced experimental diffraction researcher at King's College at the time

3 Kings College, London Sir John Randall Maurice Wilkins Rosalind Franklin Raymond Gosling Cambridge U James Watson Francis Crick Franklin and Gosling discovered that there were two forms of DNA: at high humidity, the DNA fibre became long and thin; when it was dried it became short and fat. These forms were termed DNA "B" and "A" respectively.

4  1953 – Wilkins discloses Franklin’s Photo 51 to James Watson who was working on his own DNA model with Francis Crick  1953 – Watson and Crick used what they saw in her Photo 51 and published their model of DNA and receives the Nobel Prize in 1962  1953 – Franklin goes to Birkbeck College where she studied the tobacco mosaic virus, RNA and coal  Franklin publishes 17 papers on viruses and her group laid the foundations for structural virology (study of viruses)  Franklin develops ovarian cancer and dies at age 37 in 1958

5  1992, English Heritage placed a blue plaque at 107, Donovan Court  1993, King's College London placed a blue plaque on its outside wall  1997, the asteroid discovered in 1997 was named 9241 Rosfranklin  1998, National Portrait Gallery in London added Rosalind Franklin's portrait next to those of Francis Crick, James Watson and Maurice Wilkins  2001, the American National Cancer Institute established the Rosalind E. Franklin Award for women in cancer research  2003, the Royal Society established the Rosalind Franklin Award, for an outstanding contribution to any area of natural science, engineering or technology  2004, Finch University of Health Sciences/The Chicago Medical School, was renamed the Rosalind Franklin University of Medicine and Science at Illinois  2008, Columbia University awarded an Honorary Louisa Gross Horwitz Prize to Rosalind Franklin, Ph.D., posthumously, "for her seminal contributions to the discovery of the structure of DNA“  There are college residences, a laboratory, buildings, a fellowship have been renamed/named in her honor

6 As a scientist Miss [Rosalind] Franklin was distinguished by extreme clarity and perfection in everything she undertook. Her photographs are among the most beautiful X-ray photographs of any substance ever taken. John Desmond Bernal
