Rosalind Franklin Biography:
Rosalind Franklin was born in London. Her family was well-off; her father a banker with socialist leanings who taught at the Working Men's College.
Her family was active in the public sphere. A paternal great-uncle was the first practicing Jew to serve in the British Cabinet. An aunt was involved with the women's suffrage movement and trade union organizing. Her parents were involved in resettling Jews from Europe.
Rosalind Franklin developed her interest in science at school, and by age 15 had decided to become a chemist. She had to overcome the opposition of her father, who did not want her to attend college or become a scientist; he preferred that she go into social work. She earned her Ph.D. in chemistry in 1945 at Cambridge.
After graduating, Rosalind Franklin stayed and worked for a while at Cambridge, then took a job in the coal industry, applying her knowledge and skill to the structure of coal. She went from that position to Paris, where she worked with Jacques Mering and developed techniques in x-ray crystallography, which was a leading-edge technique to explore the structure of the atoms in molecules.
Rosalind Franklin joined the scientists at the Medical Research Unit, King's College, when John Randall recruited her to work on the structure of DNA. DNA (deoxyribonucleic acid) was originally discovered in 1898 by Johann Miescher, and it was known that it was a key to genetics. But it was not until the middle of the 20th century when scientific methods had developed to where the actual structure of the molecule could be discovered, and Rosalind Franklin's work was key to that methodology.
Rosalind Franklin worked on the DNA molecule from 1951 until 1953. Using x-ray crystallography she took photographs of the B version of the molecule. A co-worker with whom Franklin did not have a good working relationship, Maurice H. F. Wilkins, Wilkins showed Franklin's photographs of DNA to James Watson, without permission of Franklin. Watson and his research partner, Francis Crick, were working independently on the structure of DNA, and Watson realized that these photographs were the scientific evidence they needed to prove that the DNA molecule was a double-stranded helix.
While Watson, in his account of the discovery of the structure of DNA, largely dismissed Franklin's role in the discovery, Crick later admitted that Franklin had been "only two steps away" from the solution, herself.
Randall had decided that the lab would not work with DNA, and so by the time her paper was published, she had moved on to Birkbeck College and the study of the structure of the tobacco mosaic virus, and she showed the helix structure of the virus' RNA. She worked at Birkbeck for for John Desmond Bernal and with Aaron Klug, whose 1982 Nobel Prize was based in part on his work with Franklin.
In 1956, Franklin discovered she had tumors in her abdomen. She continued to work while undergoing treatment for cancer. She was hospitalized at the end of 1957, returned to work in early 1958, and later that year became unable to work and then died in April.
Rosalind Franklin did not marry or have children; she conceived of her choice to go into science as giving up marriage and children.
Watson, Crick, and Wilkins were awarded the Nobel Prize in physiology and medicine in 1962, four years after Franklin died. The Nobel Prize rules limit the number of persons for any award to three, and also limit the award to those who are still alive, so Franklin was not eligible for the Nobel. Nevertheless, many have thought that she deserved explicit mention in the award, and that her key role in confirming the structure of DNA was overlooked because of her early death and the attitudes of the scientists of the time towards women scientists.
Watson's book recounting his role in the discovery of DNA displays his dismissive attitude towards "Rosy." Crick's description of Franklin's role was less negative than Watson's, and Wilkins mentioned Franklin when he accepted the Nobel. Anne Sayre wrote a biography of Rosalind Franklin, responding to the lack of credit given to her and the descriptions of Franklin by Watson and others. The wife of another scientist at the laboratory, herself a friend of Franklin, Sayre describes the clash of personalities and the sexism that had faced Franklin in her work. A. Klug used Franklin's notebooks to show how close she had come to independently discovering the structure of DNA.
In 2004, Finch University of Health Sciences/The Chicago Medical School changed its name to the Rosalind Franklin University of Medicine and Science, to honor Franklin's role in science and medicine.
