Rosalind Franklin is a british chemist who is known for her part in discovering DNA and her useof x-ray diffraction. She was born in 1920 in London and got her Ph.D. in chemistry from Cambridge.Rosalind was an exceptional crystallographer and was very good at x-ray diffraction as well. Those skillsallowed her to create the famed photo 51 which showed the structure of DNA. James Watson and FrancisCrick used this picture without her permission to create their DNA model.From the age of 15 she wanted to be a scientist. She worked at the Coal Utilization ResearchAssociation as an assistant research officer. This job was the groundwork for her Ph.D. thesis in 1945. Itwas called “The physical chemistry of solid organic colloids with special reference to coal”. One yearlater in 1946 she got a job at the Laboratoire Central des Services Chimiques de l’Etat in Paris. There sheworked with Jacques Mering who taught her X-ray diffraction. In 1951, Rosalind started working atKing’s College as a research associate. There Director John Randell used Rosalind’s skills in x-raydiffraction on DNA fibers. This is where the photo of the “B” form of DNA was created using 100 hoursof x-ray exposure in a machine that Rosalind had made. This process created photo 51. Maurice Wilkinsshared this photo without Rosalind permission with her competitor James Watson in 1953. James Watsonand Francis Crick used this photo to base their DNA model. Crick and Watson received a Nobel Prize forthat model in 1962. They had many other failed models which Rosalind laughed at knowing that theywere wrong. Crick and Watson also took most of the credit for her discovery.In 1953 Rosalind left King’s College and went to Birkbeck College. While there she studied thestructure of the tobacco mosaic virus and RNA’s structure. Rosalind’s research showed that RNA wrapsaround the helical groove inside the hole of a protein. She couldn’t continue her previous work becauseJohn Randall, the director at King’s College, let her go on the condition that she wouldn’t work on DNA.She had 17 papers on viruses in only 5 years and her group created the cornerstone of structural virology.Structural virology is the molecular mechanism used by viruses to invade host cells and establish aninfection. Rosalind learned she had ovarian cancer in 1956 and later died on April 16th, 1958, she lived tobe 37 years old.
