Plant Viruses and Rosalind Franklin's Legacy

Franklin left King's college in 1953 to work on using her x-ray diffraction techniques to study plant viruses, particularly the tobacco mosaic virus, at Birkbeck College, staying in London. It was an environment that was, once more, a respectful and accepting place for women. Franklin worked under a man named Desmond Bernal.

She worked in an old eighteenth century townhouse which had been converted into her lab space. Her lab, inconveniently enough, was on the top floor of the five story house, while the x-ray equipment was in the basement.

It was during a trip to America to look for a research grant from the NIH, in the summer of 1956, when Franklin began to experience sharp abdominal pain and swelling. On her return to London in September of that year, her doctor suspected she had ovarian cancer. It was confirmed with a surgery. The next month she had another surgery. She finally returned to work in the first month of the new year. ​​​With her illness, the placement of her lab went from inconvenient to problematic and exhausting. ​​​Throughout 1957, Franklin underwent many treatments and surgeries, going back to work as much as she could.
At Birkbeck, Franklin and her team produced a good number of journal articles, including "The Helical Arrangement of the Protein Sub-Units in Tobacco Mosaic Virus", ​"The Structure of Turnip Yellow Mosaic Virus: X-Ray Diffraction Studies", "On the Structure of Some Ribonucleoprotein Particles", "Order-Disorder Transitions in Structures Containing Helical Molecules", ​"The Structure of Viruses as Determined by X-Ray Diffraction", and ​"The Crystal Structure of Tipula Iridescent Virus as Determined by Bragg Reflection of Visible Light". ​Franklin made numerous contributions to the study of plant viruses while at Birkbeck, and even began planning a project studying the polio virus.

Legacy
Throughout her life, Rosalind Franklin made so many contributions to science. She started with using x-ray diffraction for coal research and then turned that technique to study biological molecules. She was instrumental in discovering the structure of DNA, and made great contributions to studying plant viruses. Her work with coal earlier on was groundbreaking. 
Franklin died before she was 38. I wonder what she would have done if she lived a longer life. I wonder how she would have wanted to be remembered. Some people see her as a victim -- a martyr -- of sexism in science. Others see her as an amazing scientist who accomplished so much in her short life. Others don't remember her at all. I wonder what she would have wanted. How would she have wanted her story told? How would she have wanted the world to remember what she did?

In 1951, Rosalind Franklin went back to London to work in J. T. Randall's biophysics program at King's College. It was very different from Paris. "London in the 1950s seemed to Rosalind to be sunk in pessimism, while Paris, recovering from the horrors of occupation, was forward-looking and full of optimism," writes Jennifer Glynn in her memoir My Sister Rosalind Franklin. The work environment as well was in high contrast to her last job. Sexism was built deeply into the work environment. It was very unwelcoming in contrast to Mering's lab in Paris, as Glynn describes: "There were certainly a surprising number of women scientists at King's, but they were not allowed in the men's common room, where there was lunch and coffee and contact with colleagues--an insulting situation, even if not unusual in England at the time; it hit Rosalind particularly badly after the freedom and friendliness of the lab in the Quai Henri IV. And the immediate hostility between Rosalind and her colleague Maurice Wilkins has become notorious." This was King's College in the 1950s. This was when Franklin stepped into the famous and messy race for the structure of DNA.
Franklin didn't intend to work on DNA when she came to King's College. "Franklin's fellowship proposal called for her to work on x-ray diffraction studies of proteins in solution. However, there was a shift in research priorities after Maurice Wilkins, the assistant director of Randall's lab, began working with an unusually pure sample of DNA obtained from Rudolf Signer. Excited about the possibilities, Wilkins suggested to Randall that Franklin's expertise might be better applied to this promising DNA research. Randall agreed; he wrote to Franklin in November 1950, explaining the change of plan, and stated that she and graduate student Raymond Gosling would be the only staff doing crystallographic studies of DNA. Randall did not mention Wilkins' serious interest in DNA, nor did he tell Wilkins the details of the letter. These omissions soon generated misunderstandings between Wilkins and Franklin--Franklin assumed that the x-ray diffraction studies of DNA would be her project alone; Wilkins assumed that she was joining the loosely organized research team ('Randall's Circus') at the biophysics lab, as the expert on crystallography." (The Rosalind Franklin Papers, NIH) These misconceptions heightened tensions between Franklin and Wilkins, which weren't helped by a personality conflict between the two.

Also working on DNA there, were Francis Crick and James Watson. Watson wrote a book about the race for DNA, The Double Helix​, in which he presents a very arrogant view of the events and a very sexist portrayal of Franklin. He refers to her as "Rosy" every time he talks about her in the book and called her Wilkins' assistant​. He introduced every woman he mentioned by her hair color. In regards to Franklin, he described her as follows. This is an actual excerpt from his book. I don't think it needs comment.

I suspect that in the beginning Maurice hoped that Rosy would calm down. Yet mere inspection suggested that she would not easily bend. By choice she did not emphasize her feminine qualities. Though her features were strong, she was not unattractive and might have been quite stunning had she taken even mild interest in clothes. This she did not. There was never lipstick to contrast with her straight black hair, while at the age of thirty-one her dresses showed all the imagination of English blue-stocking adolescents. So it was quite easy to imagine her the product of an unsatisfied mother who unduly stressed the desirability of professional careers that could save bright girls from marriages to dull men. But this was not the case. Her dedicated, austere life could not be thus explained--she was the daughter of a solidly comfortable, erudite banking family.
Clearly Rosy had to go or be put in her place. The former was obviously preferable because, given her belligerent moods, it would be very difficult for Maurice to maintain a dominant position that would allow him to think unhindered about DNA. Not that at times he didn't see some reason for her complaints--Kings had two combination rooms, one for men, the other for women, certainly a thing of the past. But he was not responsible, and it was no pleasure to bear the cross for the added barb that the women's combination room remained dingily pokey whereas money had been spent to make life agreeable for him and his friends when they had their morning coffee.
Unfortunately, Maurice could not see any descent way to give Rosy the boot. To start with, she had been given to think that she had a position for several years. Also, there was no denying that she had a good brain. If she could only keep her emotions under control, there would be a good chance that she could really help him.
There's no question why Franklin was unhappy there. 
It was in this environment that Franklin worked studying DNA with x-ray crystallography. It was here that Franklin and Gosling produced the famous Photograph 51 of DNA.

Wilkins showed this photo to Crick and Watson, without Franklin's knowledge or permission. Crick and Watson used this photo as crucial proof in their designs for a model of DNA. They never gave her credit for it in their journal article. The sad thing is is that Franklin never knew they took her work. We'll never get to know what she would have felt about it. 
Franklin died before Crick, Watson, and Wilkins were awarded the 1962 Nobel prize in medicine. Had she been alive, she might have gotten the credit she deserved.

Personal Life: Influences and Relationships

1945. WWII had ended, and Franklin, in June of that year, went back to Nenwham to write her Ph.D. thesis from her work at BCURA. ​Since the war was over, Franklin happily took up international travel again. During the war she had gone on mountain climbing trips and the like, but only in Britain. Now she was glad to be able to travel elsewhere as well, such as one hiking trip to the French Alps she went on with her good friend Jean Kerslake.
"If ever you hear of anybody anxious for the services of a physical chemist who knows very little about physical chemistry but a lot about the holes in coal, please let me know." This was from a letter Franklin wrote to her friend Adrienne Weill. After her trip in France, she was ready for a change of pace with her work, especially hoping for a job in France. Franklin didn't really expect to find one, but Weill was in fact able to help. "​Adrienne once more became [Franklin's] saviour, telling her that at the conference on carbon that was to take place at the Royal Institution that autumn there would be two French scientists, Marcel Mathieu and Jacques Mering, both friends of hers, who would like to meet Rosalind and might be able to help her. Rosalind presented a paper at the conference, asked intelligent questions, and showed the visiting Frenchmen round London. They were impressed," catalogues Jenifer Glynn in her memoir of her sister.
Through Marcel Mathieu, Franklin gained a position in the Laboratoire Central des Services Chimiques de l'État, in Paris, working under Mering, starting in February of 1947. She would work in Paris for four years. Glynn reports that Franklin's time in Paris was the happiest of her life.
​Franklin befriended many of the other young researchers working under Mering. One of these friends was Vittorio Luzzati. Franklin and Luzzati shared a love of adventurous trips and of energetic debates. In fact, Luzzati and his wife Denise invited Franklin joined them on plenty of these vacations.

Jenifer Gynn writes of Luzzati and Franklin's friendship: "Luzzati shared Rosalind's taste for heated discussion and argument--Anne Sayre records a colleague saying, 'When Vittorio and Rosalind were together, it was hammer and tongs and quite exhausting'. And Vittorio and his wife Denise also shared her taste for the countryside and energetic holidays. Rosalind joined them for their great bicycle tour in Tuscany in 1950--'unforgettable' as Vittorio Luzzati wrote--in a countryside as yet untouched by tourists. It is still a good memory for him.... Whenever possible they would escape to the Alps, too, or all go off to the countryside at weekends."

Franklin also developed a relationship with her supervisor, Jacques Mering. Glynn writes that Franklin thought highly of him and Mering was impressed with her abilities.
Franklin formed these good friendships and many others in Paris. Key word being friendships. People often tried to put more into them then there was. Glynn puts it well: ​"[Franklin] was twenty-six when she arrived [in Paris], and single. Paris has always had a reputation as a romantic city, so there have been various suggestions about her possible romantic life there--but all of them are wrong; her happiness came simply from a love of the place, from friendships, and from fulfilment in her work." 
People have a tendency to ship famous and historic figures, particularly the female ones. The whole thing is absurd. It is frustrating that people don't understand that a woman doesn't necessarily have to have an active romance life. 
First, they decided on Luzzati. Glynn puts the whole mess perfectly: "The BBC TV Horizon programme implied a relationship with Vittorio Luzzati; in fact, although they were colleagues and always remained excellent friends, they were certainly no more than that. Since there was no future there, Jacques Mering, Rosalind's supervisor, was later suggested as a candidate; he, as it happens, already had a wife and a mistress. Rosalind admired Mering as a scientists, and she must have felt a pang of nostalgia when he rang her and came to see her later in her illness. He reportedly wept after seeing her--as he might have done after seeing any young talented pupil close to death. It is wrong to read any more than that into their relationship."

Research Work: Coals and Carbon

In Paris, Franklin continued on an extension of her research conducted at BCURA. She wanted to look even closer at the microstructures of coals. For this, she needed X-ray diffraction! She was in the right place for this now, with Mering to teach her as needed. 
Franklin's research in Paris yielded even more published journal articles authored by her. In her time in Paris, she became very skilled at X-ray crystallography, which she would later turn towards studying biological structures. She also grew in prestige as a scientists. She is remembered in having great contributions to the field of coal and carbon research.

First Work: Properties of Coal at BCURA Part II

12/6/2021

The director of research at BCURA (the ​British Coal Utilisation Research Association) was Dr. Donald Bangham, whom Franklin coauthored a journal article with ("Thermal Expansion of Coals and Carbonised Coals," 1946, shown right).
Franklin and Bangham were researching the thermal expansion of solid coal and charcoal. Thermal expansion is how substances change their shape and size with temperature, usually not including phase changes (eg. changes between water, liquid, and gas). Usually we look at thermal expansion in gasses (such as when a sealed balloon shrinks in the cold and gets bigger in the warmth), however, Franklin and Bangham were looking at the thermal expansion of solids. (While we don't think about it as much we still do see this in our everyday lives. A common example of this is pavement contracting in the winter and resulting in potholes in the spring.)
"Thermal Expansion of Coals and Carbonised Coals" by D. H. Bangham and R. E. Franklin, 1946*
Franklin and Bangham were looking at how the thermal expansion of charcoal and coal was affected by the amount of methanol was saturated in the coal or charcoal. The expansion of charcoals with the absorbed films of alcohols is harder to measure since it's very complex: at first it expands much faster than dry charcoal, but then it shrinks before expanding again due to the moisture evaporating from it. Franklin and Bangham devised a method to measure this more accurately by a method of preheating the coals to high temperatures.  
After this paper was published, Franklin published her own journal article in 1948 ("A Study of of The Fine Structures Of Carbonaceous Solids by Measurements of True and Apparent Densities: Part I. Coals," 1948, shown below) which detailed her experiments in apparent density of coals at BCURA.
"A Study of The Fine Structures Of Carbonaceous Solids by Measurements of True and Apparent Densities: Part I. Coals" by Rosalind E. Franklin, 1948**
In this Franklin was studying the properties of pores of coals with varying carbon contents using measurements of true and apparent densities. True density is the actual density of a material. The apparent density, on the other hand, is the density measured using the volume of a liquid or gas displaced by the material. This works because the fluid should fill the holes in the sample of the material so it doesn't matter the material's shape. However, if the pores of the material are small enough, as they were with the coal samples in Franklin's experiment, the molecules of the fluid might not physically fit into the pores. Smaller molecules will fit into smaller pores while bigger ones will not, resulting in different apparent densities when measuring with different size molecules. The pore size not only affects the apparent densities when using different molecules, but also how fast they can seep into the pores. Franklin measured the apparent density of a coal in a particular fluid over time, not just at first, which allows molecules time to seep into the pores. This change in apparent density is called the drift.
Smaller molecules (helium is a great) give apparent densities closer to the true densities of materials. No matter how small of a molecule you use, however, it will not fill completely closed off holes in the material.
The fluids Franklin used in her experiment were helium gas, methanol, water, n-Hexane, and benzene. The chemical structures of these gasses and liquids are shown in the above order below. (Note: If you are not familiar with Lewis Structure notation, in short, the two dots represent unbonded electrons and the lines represent bonds. (The triangle shapes in the structure for n-Hexane indicate 3D shape.))

The second part of Franklin's article, "A Study of of The Fine Structures Of Carbonaceous Solids by Measurements of True and Apparent Densities: Part II. Carbonized Coals" (shown below) was published in 1949.
"A Study of of The Fine Structures Of Carbonaceous Solids by Measurements of True and Apparent Densities: Part II. Carbonized Coals" by Rosalind E. Franklin, 1949***
In this article, she details her experiments studying cokes (carbonized coals) using apparent density measurements, again using a variety of liquids and gasses. She compared this apparent density data for varying types of cokes carbonized in a range of carbonization temperatures. 
This molecular sieve property which Franklin observed in these experiments, is of great importance today, as I mentioned previously. In part II, Franklin writes on several occasions that this property must be very important. In her abstract she wrote "This molecular sieve structure must be of importance in determining both the chemical behavior of the solid and the composition of the gas evolved during carbonization." In addition, in the last part of her results section, "Molecular Sieve Properties of Carbonized Coals," which specifically focuses on this property, she again writes how she believes the molecular sieve properties are of great importance.

First Work: Properties of Coal at BCURA Part I

11/28/2021

BCURA (the ​British Coal Utilisation Research Association) had been founded in 1938, only four years before Rosalind Franklin came there. It was located at Kingston-on-Thames, outside London, and, in Franklin's words, was "miles from anything." She also expected limited social engagement, as she would be primarily dining and living around "lab people" which she expected to be boring compared to the more varied crowd she spent time with at Cambridge.
​Franklin's worries about the social atmosphere were partly resolved when she moved in with her cousin Irene, a college friend of this cousin, and one other roommate: a black and white kitten!

 Franklin and her cousin volunteered as air-raid wardens during this time. Their jobs involved making sure the 'blackouts' were observed adequately, serving two-hour shifts at the wardens' post, and going out in emergency situations. These were quite trying experiences for Franklin, as Jenifer Glynn, Franklin's sister, explained in her memoir: "Crossing Putney Common for her duties, at night during air raids, was a worse ordeal for Rosalind that we realized at the time--sometimes in the distress of her last illness it haunted her dreams."
Franklin grew in prestige during her time working for BCURA. She worked on her research there for four years (ending in 1946).
BCURA did research in coal, relating to the war. Franklin's studies, in particular, focused on tiny pores in coal. Franklin's research was a huge contribution to the study of coals. For example, in a quote Glynn included in her memoir, Peter Harris wrote in reference to Franklin's work: "This was probably the first demonstration of molecular sieve behaviour in any carbon. Today [2001], carbon molecular sieves are of great value in industry where, among other things, they are used to separate nitrogen from oxygen in air."*
Franklin's research at BCURA involving the properties of coal, which I will expand more upon in the next post, became her dissertation for her Ph.D. (which she received from Cambridge in 1945) as well as several published scientific journal articles.

Transition from School to Work

11/16/2021

Rosalind Franklin got her Bachelor's degree in Physical Chemistry in 1941. She didn't leave Cambridge until 1942, though. She had received a research grant and a scholarship for another year at Cambridge as a research student. 
She worked under Ronald Norrish who was the Professor of Physical Chemistry in the area of research on the kinetics of polymerization reactions. While he was an impressive scientist (in fact, he would go on to win a Nobel in 1967), he was often criticized for being a stubborn and inflexible professor to his students, especially the women. 
Franklin was frustrated with the work Norrish assigned her. She felt it didn't help the war effort and wasn't worth her time. She also disagreed with some of his conclusions. She was frustrated with his inattentiveness to her ideas. She was usually very direct and honest about her point of view, so she voiced these concerns to him. This, of course, often didn't bode well. Their two conflicting personalities and differing ideas often led to conflicts in their relationship. Franklin complained about him some of her letters. In a letter addressed to her family, written in December, she voiced her frustrations:
I'm only just beginning to realise how well justified his bad reputation is. Well I've now got ​thoroughly on the wrong side of him, and almost reached a deadlock. He's the sort of person who likes you all right as long as you say yes to everything he says and agree with all his mis-statements, and I always refuse to do that. He tells me I mustn't take any step without asking him and has now run out of ideas and tells me to go back and try the first method again (after I proved three months ago that it didn't work). I refused, and we parted angry....
She cut her time as a research student at Cambridge short. While she could have stayed up to two or three years working there, she found the work not worthwhile enough for her and left in 1942. 
While she disliked her work during her time researching at Cambridge, she did enjoy her personal life. She lived alone -- and quite liked it, according to her letters home -- and enjoyed her independence. She liked reading, having visits from friends and family, and going to theaters and art exhibits according to her sister. When her college friends left Cambridge, though, she felt lonelier. In one melancholy letter home, she wrote:
​I live alone, and most of my friends have gone--all the friends that remain go down for good this month. I am intensely bored with my work, I despise my professor. I dislike the men who work in my lab, and they resent and generally ignore my presence.
Franklin's friend Adrienne Weill came along and pulled her out of her loneliness. Adrienne Weill was a French Jewish refugee and scientist who came to Cambridge during Franklin's time at Newnham. She developed into Franklin's role model and friend.
In May, Weill invited Franklin to stay at her house for foreign students. While at first hesitant, Franklin accepted and moved in in June.
Also in June, the Ministry of Labour announced that women research students were now able to be 'drafted' into war related work. While her work at Cambridge was stable and could be considered war work, she decided to take a chance and look for different research work, more directly related to the war effort. This is how we come to the ​British Coal Utilisation Research Association (BCURA).
​​BCURA offered Rosalind Franklin an opportunity to gain her Ph.D. while working for them. Franklin also disliked her research experience at Cambridge, so the benefits of switching to work at BCURA were obvious. However, Franklin was hesitant. Particularly, she wasn't too happy about the isolation of the lab, which would be several miles away from town. This would be a contrast to her current life living in Weill's international house. She also may have been disappointed in having to stop teaching.
In the end she accepted BCURA's offer. And so, during the year 1942, she arrived at Kingston-on-Thames, right outside London, to work in coal research in the position of Assistant Research Officer in BCURA.

Rosalind Franklin Outside of School

Rosalind Franklin grew a lot during her time at school. She became very vocal and serious about politics, as her sister describes in her memoir: "Her very full and frequent letters show her gradually maturing from her schoolgirl outlook, when she tended to echo her parents' beliefs (except in religion, which she had already firmly rejected), to her own outspoken left-wing independence." She would often write about politics in her letters while she was at Newnham.
She was very vocal about issues at school, too, and would write about it to her family and sometimes criticisms to the school about their teaching. She was also unhappy about how the war was impacting her school, which she complained about in letters home. She wrote to her family about her complaints, politics, her schooling, exams, and interesting occurrences in day-to-day life. During war-time she would write about air-raids and other war-related events that were happening around her.
Franklin was very serious about political issues and her work, however she didn't have no social life. For example, she attended a skiing trip in Switzerland. She enjoyed skiing, even though, of course, it was not easy for a beginner like her, especially since this was prior to ski lifts! She preferred climbing, however, to skiing. She also enjoyed hiking. "She played hockey, squash, and tennis, and skated on frozen fens," her sister describes. Franklin liked to do these outdoor activities as a break from the stress of her schoolwork and, later, work. 
She was involved in school clubs as well. She joined the Chemical Society, the Archimedians (the math club), and the Jewish Society in her first term at Cambridge.

WWII started during Franklin's second year at Cambridge. Her father believed that she should be doing something more for the war effort, while Franklin believed she would do the most good to continue to pursue her degree in chemistry. "As my father saw it, Rosalind was taking an unwarranted soft option," Franklin's sister writes in her memoir My Sister Rosalind Franklin, "this was the time when my mother … firmly took Rosalind's side, convinced that she was right to stay in Newnham. Rosalind was, as she herself explained to my father, anxious to do some sort of war work in the vacations, helping my parents with their work for refugees, and was anxious, too, to have some sort of war work using her scientific skills when she graduated--it was then, after all, 1941, and the country was still in crisis. By the time the war was over, the direction of Rosalind's life was clear."
She was introduced to x-ray crystallography in college. I was very fortunate to find some of her notes from her college classes.*

She did very well in school, however, she was always very nervous about exams. She often performed very well, though. She wrote many letters home about her anxiety about her exams in college.
Franklin went on to get a degree in physical chemistry. In 1942, she left college and began her work with coal.

Childhood

Rosalind Franklin was born on July 25, 1920, in Chepstow Villas in Notting Hill, London to Ellis and Muriel Franklin. The Franklins were a prominent Anglo-Jewish family in Notting Hill. They had five kids, Rosalind Franklin being the second oldest of them.
Rosalind Franklin showed her intelligence early on as a kid. Her family had always intended for her to have an education, and didn't have any reservations about her being a smart woman. "My parents were delighted to have intelligent children of either sex," her sister writes in her memoir, My Sister Rosalind Franklin, "sent us all to academic schools, expected us all to go to university, and we were well used to intelligent women in the family."
Picture

She was fascinated by science at a young age. Her brother Colin describes how she loved printing photographs with her mother: "Developing and printing photographs at home, with my mother, was a discovery which thrilled her in childhood, swilling the sensitised paper in a tray of water... watching the image appear, removing it at the right moment of development. I remember her exclamation which pleased my mother, 'It makes me feel all squidgy inside.'"
She began attending St. Paul's Girls' School at age 11 in 1931. She was already showing signs of her interest in science at that age. Her sister described that "early traces of a careful and excited scientist had already appeared [in Franklin].... Indeed, many traits of her character were already clear -- her intelligence, her skill with her hands, her perfectionism, her logical mind, her outspoken honesty." Her mother also said: "All her life, Rosalind knew exactly where she was going, and at sixteen, she took science for her subject."
​ Franklin did very well in school. As her sister says, "Rosalind's school certificate, in spite of the usual exam nerves, brought her six distinctions, an easy overkill for a matric. For she was able at all subjects, and particularly interested in history, though she never doubted that specialization meant science. And it was to be physical sciences and maths, not biology or botany which were mainly for those wanting to be doctors."
She decided to go to Newnham College at Cambridge University. Newnham was one of the two women's colleges at Cambridge University, the other being Girton. She chose Cambridge because, as her sister puts it: "Cambridge, it was assumed, was the best place for science." And in 1938, a year early, she headed off to Cambridge.

Rosalind Franklin is most well known for her uncredited contribution to the discovery of the structure of DNA. In fact, her crucial photograph of its structure is the background of this page. For such an important part of such an impressive discovery, she isn't very well known. 
Rosalind Franklin, 1955, MRC Laboratory of Molecular Biology
She didn't just do work in DNA. She made great contributions to other studies. She did research involving the micro-structures of coal before she worked on DNA. After her work with DNA, she changed to studying plant viruses.
In this blog, I will tell her story. I'll start with her childhood and tell the story of her life up until her untimely death. I'll also explain the chemistry behind her work. Read more to learn about this amazing scientist and what she's done for the world.
