Rosalind Franklin Biography : In the annals of scientific history, few stories are as compelling and controversial as that of Rosalind Franklin. A brilliant chemist and X-ray crystallographer, Franklin played a crucial role in one of the most significant scientific discoveries of the 20th century – the structure of DNA. Yet, for many years, her contributions were overlooked, her work undervalued, and her legacy overshadowed by the men who would go on to win the Nobel Prize for the discovery she helped make possible. This is the story of Rosalind Franklin, a pioneering woman in science whose life was cut tragically short, but whose impact continues to resonate in the fields of genetics, chemistry, and beyond.
Rosalind Elsie Franklin was born on July 25, 1920, in Notting Hill, London, into a prominent Anglo-Jewish family. She was the second of five children born to Ellis Arthur Franklin, a merchant banker, and Muriel Frances Waley. The Franklins were a family of considerable means and social standing, known for their commitment to public service and liberal politics. From an early age, Rosalind was exposed to a rich intellectual environment that valued education, debate, and social responsibility.
Young Rosalind showed an early aptitude for science and mathematics, standing out in these subjects at St Paul’s Girls’ School, one of the top schools for girls in London. Her aunt, Helen Bentwich, later recalled, “All her life, Rosalind knew exactly where she was going, and at sixteen, she decided she would be a scientist.” This determination would shape the course of her life, leading her to pursue a path that was still relatively uncommon for women of her time.
In 1938, Franklin entered Newnham College, Cambridge, to study chemistry. Her time at Cambridge coincided with the outbreak of World War II, which had a significant impact on university life. Despite the challenges posed by wartime conditions, Franklin excelled in her studies, earning second-class honors in her finals in 1941. Her degree, however, was not officially awarded until 1947, as Cambridge did not formally grant degrees to women until 1948.
After graduating, Franklin worked for a year as a research chemist at the British Coal Utilisation Research Association (BCURA). Here, she conducted important research on the porosity of coal, work that formed the basis of her Ph.D. thesis. Her research at BCURA was not only scientifically valuable but also had practical applications for the war effort, as it helped in the development of more efficient gas masks.
In 1945, Franklin was awarded a Ph.D. from Cambridge University for her thesis titled “The physical chemistry of solid organic colloids with special reference to coal.” This work established her as a skilled researcher with a talent for precise, meticulous experimentation – qualities that would serve her well in her future work with X-ray crystallography.
Following the completion of her Ph.D., Franklin received a position at the Laboratoire Central des Services Chimiques de l’État in Paris, where she worked from 1947 to 1950. It was during this time that she became an expert in X-ray diffraction techniques under the tutelage of Jacques Mering. This period in Paris was a happy and productive one for Franklin. She enjoyed the cosmopolitan atmosphere of post-war Paris and formed close friendships with many of her colleagues. More importantly, she honed the skills that would later prove crucial in her work on DNA.
In 1950, Franklin returned to England to take up a research scholarship at King’s College London in the Medical Research Council’s (MRC) Biophysics Unit. It was here that she began her work on DNA, a project that would define her scientific legacy but also become a source of personal and professional conflict.
When Franklin arrived at King’s, she was assigned to work on DNA fibers with Ph.D. student Raymond Gosling. Her director, John Randall, had given her the task of elucidating the structure of DNA using X-ray crystallography. This was cutting-edge research at the time, as the importance of DNA in heredity was just beginning to be understood.
Franklin approached her work with characteristic thoroughness and skill. She improved the techniques for creating DNA fibers and took increasingly clear X-ray diffraction images. Her most famous image, known as “Photograph 51,” was an exceptionally clear X-ray diffraction pattern of DNA that clearly showed its helical structure.
However, Franklin’s time at King’s was marked by tension and conflict, particularly with her colleague Maurice Wilkins. There seems to have been a misunderstanding from the start about Franklin’s role in the lab. Wilkins had been working on DNA before Franklin’s arrival and expected her to be his assistant. Franklin, on the other hand, had been told by Randall that the DNA project would be her own. This misunderstanding led to a breakdown in communication and cooperation between Franklin and Wilkins that would have far-reaching consequences.
Despite these personal conflicts, Franklin’s work at King’s was groundbreaking. By 1952, she had evidence that DNA existed in two forms, which she labeled “A” and “B.” She also determined that the phosphate groups in DNA were located on the outside of the molecule, a crucial insight for understanding its structure.
In January 1953, Franklin was preparing to leave King’s for Birkbeck College. Before she left, she submitted a report summarizing her work on DNA. Unbeknownst to her, this report, along with her famous “Photograph 51,” was shown to James Watson by Maurice Wilkins. Watson, along with Francis Crick at Cambridge University, was also working on determining the structure of DNA.
The information in Franklin’s report and her X-ray image provided Watson and Crick with key insights that allowed them to build their correct model of the DNA double helix. They published their model in Nature in April 1953, alongside a paper by Wilkins and another by Franklin and Gosling. However, Watson and Crick’s paper contained only a vague acknowledgment of Franklin’s contribution, stating that they had been “stimulated by a knowledge of the general nature of the unpublished experimental results and ideas of Dr. M. H. F. Wilkins, Dr. R. E. Franklin and their co-workers at King’s College, London.”
Franklin moved to Birkbeck College in March 1953, where she led a research team studying the structure of viruses. This work was highly successful and respected. She and her team produced high-quality X-ray diffraction pictures of viruses and made significant contributions to understanding their structure. Her work on the tobacco mosaic virus was particularly noteworthy and is considered by many to be her finest work.
During her time at Birkbeck, Franklin also maintained an active interest in the structure of DNA and continued to make contributions to its understanding. She had a cordial professional relationship with Watson and Crick during this period, even visiting their lab in Cambridge. However, she was never fully aware of the extent to which her work had contributed to their Nobel Prize-winning model.
Tragically, Franklin’s scientific career was cut short. In the summer of 1956, she was diagnosed with ovarian cancer. Despite undergoing treatment, including several operations and experimental chemotherapy, her condition deteriorated. Remarkably, she continued her scientific work almost until the end, publishing seven papers in 1956 and 1957, and her last paper in 1958.
Rosalind Franklin died on April 16, 1958, at the age of 37. Her death came just as the importance of DNA in molecular biology was becoming fully recognized. Watson, Crick, and Wilkins received the Nobel Prize for their work on DNA in 1962, four years after Franklin’s death. Nobel Prizes are not awarded posthumously, but even if Franklin had been alive, it’s unclear whether she would have been included in the award given the politics and biases of the time.
In the years following her death, Franklin’s contribution to the discovery of DNA’s structure was largely overlooked. It wasn’t until the 1968 publication of Watson’s book “The Double Helix” that her role began to be more widely discussed. However, Watson’s portrayal of Franklin in the book was largely unflattering, depicting her as difficult to work with and undervaluing her scientific contributions.
This characterization sparked a reassessment of Franklin’s role in the discovery of DNA’s structure. Over the following decades, as more information came to light and attitudes towards women in science evolved, Franklin’s crucial contributions began to be more widely recognized and celebrated.
Today, Rosalind Franklin is acknowledged as a key figure in the discovery of DNA’s structure. Her skill in X-ray crystallography, her meticulous approach to research, and her insightful interpretations were crucial in unraveling the mystery of DNA’s structure. The famous “Photograph 51,” taken by Franklin and Gosling, is now iconic, recognized as visual proof of DNA’s double helix structure.
Beyond her work on DNA, Franklin made significant contributions to the understanding of the molecular structures of viruses, coal, and graphite. Her research on the tobacco mosaic virus helped lay the groundwork for structural virology. Her earlier work on the porosity of coal was important for both theoretical and practical applications.
Franklin’s legacy extends beyond her scientific achievements. Her story has become a symbol of the challenges faced by women in science, particularly in the mid-20th century. The belated recognition of her contributions has sparked important discussions about gender bias in science and the ways in which women’s work has often been undervalued or overlooked.
In recent years, there have been numerous efforts to honor Franklin’s memory and contributions. In 2004, the Chicago Medical School was renamed the Rosalind Franklin University of Medicine and Science. The European Space Agency named its Mars rover, planned for launch in 2023, “Rosalind Franklin.” Numerous books, plays, and films have been produced about her life and work, helping to bring her story to a wider audience.
Franklin’s personal life has also been a subject of interest and speculation. She never married or had children, focusing instead on her scientific career. This was an unusual choice for a woman of her time and social background, and it has sometimes been used to portray her as cold or unfeminine. However, accounts from friends and colleagues paint a picture of a warm, witty woman with a love of travel, hiking, and good food.
Franklin’s niece, the scientist Jenifer Glynn, has written about her aunt’s life, providing a more personal perspective. She describes Franklin as someone who “did not suffer fools gladly” but who was also kind and generous, with a strong sense of social justice inherited from her family.
Franklin’s Jewish heritage was also an important part of her identity, although she was not religiously observant. Her family had a strong tradition of public service, and Franklin shared this commitment. During World War II, she worked with Jewish refugees, helping them to find homes and employment in Britain.
The story of Rosalind Franklin is not just a tale of scientific discovery, but also one of perseverance in the face of institutional sexism, of rigorous and innovative research practices, and of the complex interplay between individual scientists and the broader scientific community. It raises important questions about credit and recognition in science, about the collaborative nature of scientific discovery, and about the barriers faced by women and minorities in STEM fields.
Franklin’s work ethic and approach to science were remarkable. Colleagues remember her as intensely focused and meticulous in her work. She was known for her critical thinking skills and her ability to interpret complex data. These qualities, combined with her expertise in X-ray crystallography, made her uniquely suited to tackle the challenge of determining DNA’s structure.
It’s worth noting that while the discovery of DNA’s structure is what Franklin is most famous for, her later work on viruses was equally important. Her research on the tobacco mosaic virus and polio virus was groundbreaking and helped establish the field of structural virology. This work, which she considered her best, demonstrated not only her technical skill but also her ability to apply her expertise to new and challenging problems.
Franklin’s story also highlights the importance of interdisciplinary approaches in science. Her background in physical chemistry and her expertise in X-ray crystallography allowed her to make significant contributions to molecular biology, a field that was just emerging at the time. This crossing of disciplinary boundaries is increasingly recognized as crucial for scientific advancement.
The controversy surrounding Franklin’s role in the discovery of DNA’s structure has led to broader discussions about how scientific discoveries are made and credited. It has highlighted the often collaborative nature of scientific research and the difficulty of attributing complex discoveries to individuals. It has also led to a reexamination of how the contributions of women and minorities in science have often been undervalued or overlooked.
In recent years, there has been a growing movement to recognize and celebrate women in STEM fields, with Franklin often held up as an example of a brilliant scientist whose contributions were not fully recognized in her lifetime. Programs and initiatives named after Franklin aim to support and encourage young women pursuing careers in science.
Franklin’s legacy also extends to the field of research ethics. The use of her data by Watson and Crick without her knowledge or consent has been widely criticized and has contributed to discussions about proper attribution and the sharing of scientific data.
Despite the recognition Franklin has received posthumously, there remains debate about whether she would have solved the structure of DNA herself if given more time. Some argue that she was close to figuring it out, while others contend that her approach, focusing on rigorous data collection rather than model building, may have delayed her arrival at the correct structure. This debate underscores the different approaches to scientific problem-solving and the unpredictable nature of scientific discovery.
Rosalind Franklin’s life and work continue to fascinate and inspire. Her story is one of scientific brilliance, of dedication to research, and of the complex human dynamics that underlie scientific discovery. It’s a story that reminds us of the importance of recognizing and supporting diversity in science, of the value of rigorous and methodical research, and of the often-winding path of scientific progress.
