Great Women in Science: Rosalind Franklin

Rosy Franklin, Watson, Crick, DNA helix structure,
X-ray crystallography
Born: London, England, July 25, 1920
Died: London, England, April 16, 1958
There is probably
no other woman scientist with as much controversy surrounding her life
and work as Rosalind Franklin. Franklin was responsible for much
of the research and discovery work that led to the understanding of the
structure of deoxyribonucleic acid, DNA.
Rosalin Franklin
The story
of DNA is a tale of competition and intrigue, told one way in James Watson's
book The Double Helix, and quite another in Anne Sayre's study, Rosalind
Franklin and DNA. James Watson, Francis Crick, and Maurice Wilkins received
a Nobel Prize for the double-helix model of DNA in 1962, four years after
Franklin's death at age 37 from ovarian cancer.
Rosaland Franklin
Franklin excelled
at science and attended one of the few girls' schools in London that taught
physics and chemistry. When she was 15, she decided to become a scientist.
Her father was decidedly against higher education for women and wanted
Rosalind to be a social worker. Ultimately he relented, and in 1938 she
enrolled at Newnham College, Cambridge, graduating in 1941.
Rosilyn Franklin
She held a
graduate fellowship for a year, but quit in 1942 to work at the British
Coal Utilization Research Association, where she made fundamental studies
of carbon and graphite microstructures. This work was the basis of her
doctorate in physical chemistry, which she earned from Cambridge University
in 1945.

After Cambridge,
she spent three productive years (1947-1950) in Paris at the Laboratoire
Central des Services Chimiques de L'Etat, where she learned X-ray diffraction
techniques. In 1951, she returned to England as a research associate in
John Randall's laboratory at King's College, Cambridge.

It was in
Randall's lab that she crossed paths with Maurice Wilkins. She and Wilkins
led separate research groups and had separate projects, although both were
concerned with DNA. When Randall gave Franklin responsibility for her DNA
project, no one had worked on it for months. Wilkins was away at the time,
and when he returned he misunderstood her role, behaving as though she
were a technical assistant. Both scientists were actually peers. His mistake,
acknowledged but never overcome, was not surprising given the climate for
women at Cambridge then. Only males were allowed in the university dining
rooms, and after hours Franklin's colleagues went to men-only pubs.

But Franklin
persisted on the DNA project. J. D. Bernal called her X-ray photographs
of DNA, "the most beautiful X-rayphotographs of any substance ever taken."
Between 1951 and 1953 Rosalind Franklin came very close to solving the
DNA structure. She was beaten to publication by Crick and Watson in part
because of the friction between Wilkins and herself. At one point, Wilkins
showed Watson one of Franklin's crystallographic portraits of DNA.
When he saw the picture, the solution became apparent to him, and the results
went into an article in Nature almost immediately. Franklin's work did
appear as a supporting article in the same issue of the journal.
A debate about
the amount of credit due to Franklin continues. What is clear is that she
did have a meaningful role in learning the structure of DNA and that she
was a scientist of the first rank. Franklin moved to J. D. Bernal's lab
at Birkbeck College, where she did very fruitful work on the tobacco mosaic
virus. She also began work on the polio virus. In the summer of 1956,
Rosalind Franklin became ill with cancer. She died less than two years
later.
