Rosalind Franklin | Biography

Chemist

At the Randall's Biophysics Unit at King's College, London, Dr. Randall originally hired Rosalind Franklin to set up the Crystallography section and study the structure of Proteins. But, she was asked to investigate the DNA instead. With continuous mathematical computations and over 100 hours of exposure to photographic radiations, Franklin captured the second image B and named it 'Photo 51,' coming up with the discovery of the double-helix structure of DNA. However, the credit was taken away by other Chemists of her period, Francis Crick, James Watson, and Maurice Wilkins, who later received 'The Nobel Prize' in 1962 for the same.

Rosalind Franklin was an English chemist who bore an instrumental name in discovering the structure of DNA. She also played a key role in setting the groundwork for structural virology by providing new insights into the structure of viruses.

Who is Rosalind Franklin?

A Chemist, researcher, and foremost expert in crystallography, Franklin captured the B form of DNA and named it as 'Photo 51', but unfortunately, her discoveries were predominantly unrecognized for nearly 50 years. 

Overcoming the odds faced by women in those days, especially women in the field of science, Franklin investigated the DNA structure through incessant engagement in mathematical computations and more than 100 hours of exposure to photographic radiations to come up with 'Photo 51.'

Her pioneering research and findings were a precursor to discovering the double-helix structure of DNA, but Watson and Crick proposed it in 1953. Her efforts in those days, which have improved health and longevity around the world today, were highly overlooked back then. Her photograph 'Photo 51,' which disseminated key insights into DNA structure, was cleverly used by Watson and Crick to support their theory and claimed the credit. It may be noted that Francis Crick, James Watson and Maurice Wilkins received The Nobel Prize in Physiology or Medicine in 1962 for the same, but Rosalind Franklin was not even given a mention. .

By the end of 1953, Franklin had stopped studying DNA and chose another field, Structural Virology, where she made a significant contribution in identifying the location of TMV's genetic material (RNA). It was found lodged in the inner wall of its protective protein shell.

Early Life and Education

Rosalind Franklin, full name, Rosalind Elsie Franklin, was born on 25 July 1920, in London, England. Franklin was raised in a well-to-do Anglo-Jewish family that was into Banking, Publishing, and Community Services. She was the second of five daughters in the family. Her father, Ellis Franklin, shared a partnership with publisher Routledge and Kegan Paul at Keyser's Bank, one of the family's major businesses. In addition to business, he and his wife Muriel were both active in public service and charity. 

Degrees in Science

She acquired education at preparatory schools like North London Collegiate School and St. Paul's School for Girls, where she showed great excellence in science. As she had a passionate knack for math and science from an early age, Franklin left St. Paul's School in 1938 to attend Newnham College, one of two women's colleges at Cambridge University. She studied Physics and Chemistry at the University. 

Even though World War II much influenced her undergraduate years as many professionals, especially in science, were drafted for war service, Franklin successfully graduated with Second Class Honors in her finals in 1941. Her qualification was equivalent to the bachelor's degree in terms of job credentials at the time. Franklin then received her Ph.D. degree from Cambridge in 1945 with the help of the British Coal Utilisation Research Association (BCURA). She yielded a doctoral thesis on coal porosity and about five scientific papers from her study at BCURA.

Career

After earning her BA in 1941, the Department of Scientific and Industrial Science granted her a fellowship to do one year of research along with the research endowment. That year, she worked in the lab of R. G. W. Norrish, a specialist in photochemistry. With the war already going on in 1942, she had to choose between being enlisted for more conventional war service or pursuing a Ph.D.-oriented research role in an area related to wartime demands. She decided on the latter and began working in British Coal Use Research Association. Subsequently, she completed her Ph.D. thesis titled 'The Physical Chemistry of Solid Organic Colloids with Special Reference to Coal and Related Materials' in 1945, which provided her the opportunity to tour around the role as a guest speaker.

Dr. Franklin moved to Paris in 1946 and invested four years in postgraduate research at Paris' Laboratoire Central des Services Chimiques de l'Etat. Those four years helped her gain expertise in X-ray crystallography skills, which later became her biggest strength. By the age of 30, she had established herself as an international authority on carbons, with several publications in peer-reviewed journals to her name. In 1950, she received a three-year Turner and Newall Research Fellowship in John T. Randall's Biophysics Unit at King's College, London. Despite her admiration for the autonomy and way of life in Paris, she returned to London to pursue her job at King's College.

At King's College

At the Randall's Biophysics Unit at King's College, Dr. Randall had intended to have Franklin establish the crystallography section and work on protein analysis. However, at the request of the assistant lab chief, Maurice Wilkins, Randall placed Franklin to look into DNA instead. In less than eight months after starting at King's in early 1951, Franklin took patently apparent X-ray diffraction photographs of DNA, finally discovering that there were two forms—wet and dry—that produced very different images, and both had two helices. 

Robbed of Credit on the Discovery of the Structure of DNA

Franklin and Wilkins initially worked together to study the structure of DNA. Later, they walked separate ways due to some misunderstanding that came their way and their opposing personalities, which gave rise to conflict. Although Franklin didn't care about the situation and continued working alone, Wilkins, on the other side, sought company at the Cavendish Laboratory in Cambridge, where his friend Francis Crick was working on a model of the DNA molecule with James Watson. Her original study, which lasted over a year, eventually resulted in the discovery of DNA.

Franklin had no idea that Watson and Crick had seen some of her game-changing unpublished results, including the magnificent 'Photo 51' that Wilkins had shown to Watson. Watson was inspired by the X-ray diffraction image of a DNA molecule (the pattern was a helix). Watson and Crick then developed their famous DNA model using Franklin's photograph in combination with their data. As they sent a formal account of her incomplete observations to publish it in Nature, the pair neither told Franklin that they had seen her materials nor did they expressly accept their debt to her work.

Venture into the field of Virology

Franklin decided to put a stop to working on DNA and arranged for her fellowship to be transferred to J. D. Bernal's crystallography laboratory at Birkbeck College and focused on the structure of plant viruses, especially Tobacco Mosaic Virus (TMV). There, she worked with a team that included future Nobel Laureate Aaron Klug to capture meticulous X-ray diffraction images of the viruses. Her analysis of the diffraction patterns clued to, among other things, that TMV's genetic material (RNA) was lodged in the inner wall of its protective protein shell. Within five years, Franklin published 17 scholarly papers on viruses. Her group laid a profound foundation for structural virology.

Challenges 

Despite her intellect, perfect test scores, scholarship, and desire to remain committed to the science industry, she faced many humiliations and sexist encounters. From how the credit for her work on the DNA was wrongfully taken away; to her time at Birkbeck College, where she was told to stop researching and quit fretting about her DNA studies, she had to deal with everything.

Franklin's friend Anne Sayre wrote a biography in 1975 as a vehement rebuttal to James Watson's book 'The Double Helix: A Personal Account of the Discovery of the Structure of DNA,' and to explain the world about Franklin's involvement in the discovery.

"While the male staff at King's crashed in a big, cozy, somewhat clubby dining room," Sayre claims, "the female staff of all grades had their lunch in the student's hall or further from the premises."

Early Death

Franklin was diagnosed with ovarian cancer in September 1956, said to be due to continuous exposure to X-rays. Despite three operations and experimental chemotherapy, she continued to work for the next two years. She had a 10-month remission and continued to work until a few weeks before her death on 16 April 1958, at 37.

She regularly posted articles - 19 on coals and carbons, five on DNA, and 21 on viruses and their structure throughout her life. Her papers provided her with several opportunities to speak at renowned conferences and conventions worldwide during her last few years. If only she had not acquired the disease and had lived more, she would have gained numerous professional accolades and recognition. 

In 2003, The Royal Society introduced the 'Rosalind Franklin Award' to support and promote women in Science, Technology, Engineering, and Mathematics (STEM).

In recognition of her contributions, Rosalind Franklin University of Medicine and Science became the first medical institution in the United States to commemorate a female scientist with an honorable namesake on 27 January 2004.
