Rosalind Franklin

Franklin's father, Ellis Arthur Franklin (1894–1964), was a politically liberal London merchant banker who taught at the city's Working Men's College, and her mother was Muriel Frances Waley (1894–1976).

Rosalind was the elder daughter and the second child in the family of five children.

Franklin's paternal great-uncle was Herbert Samuel (later Viscount Samuel), who was the Home Secretary in 1916 and the first practising Jew to serve in the British Cabinet.

Her aunt, Helen Caroline Franklin, known in the family as Mamie, was married to Norman de Mattos Bentwich, who was the Attorney General in the British Mandate of Palestine.

Helen was active in trade union organisation and the women's suffrage movement and was later a member of the London County Council.

Franklin's uncle, Hugh Franklin, was another prominent figure in the suffrage movement, although his actions therein embarrassed the Franklin family.

Rosalind's middle name, "Elsie", was in memory of Hugh's first wife, who died in the 1918 flu pandemic.

Her family was actively involved with the Working Men's College, where her father taught the subjects of electricity, magnetism, and the history of the Great War in the evenings, later becoming the vice principal.

Franklin's parents helped settle Jewish refugees from Europe who had escaped the Nazis, particularly those from the Kindertransport.

They took in two Jewish children to their home, and one of them, a nine-year-old Austrian, Evi Eisenstädter, shared Jenifer's room.

(Evi's father Hans Mathias Eisenstädter had been imprisoned in Buchenwald, and after liberation, the family adopted the surname "Ellis".)

From early childhood, Franklin showed exceptional scholastic abilities.

At age six, she joined her brother Roland at Norland Place School, a private day school in West London.

At that time, her aunt Mamie (Helen Bentwich), described her to her husband: "Rosalind is alarmingly clever – she spends all her time doing arithmetic for pleasure, and invariably gets her sums right."

Franklin also developed an early interest in cricket and hockey.

At age nine, she entered a boarding school, Lindores School for Young Ladies in Sussex.

The school was near the seaside, and the family wanted a good environment for Franklin's delicate health.

Franklin was 11 when she went to St Paul's Girls' School in Hammersmith, west London, one of the few girls' schools in London that taught physics and chemistry.

At St Paul's, she excelled in science, Latin, and sports.

Franklin also learned German, and became fluent in French, a language she would later find useful.

Franklin topped her classes, and won annual awards.

Her only educational weakness was in music, for which the school music director, the composer Gustav Holst, once called upon her mother to enquire whether she might have suffered from hearing problems or tonsillitis.

David (1919–1986) was the eldest brother while Colin (1923–2020), Roland (1926–2024), and Jenifer (born 1929) were her younger siblings.

Rosalind Elsie Franklin (25 July 1920 – 16 April 1958) was a British chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite.

Although her works on coal and viruses were appreciated in her lifetime, Franklin's contributions to the discovery of the structure of DNA were largely unrecognized during her life, for which Franklin has been variously referred to as the "wronged heroine", the "dark lady of DNA", the "forgotten heroine", a "feminist icon", and the "Sylvia Plath of molecular biology".

With six distinctions, Franklin passed her matriculation in 1938, winning a scholarship for university, the School Leaving Exhibition of £30 a year for three years, and £5 from her grandfather.

Franklin's father asked her to give the scholarship to a deserving refugee student.

Franklin went to Newnham College, Cambridge, in 1938 and studied chemistry within the Natural Sciences Tripos.

Franklin graduated in 1941 with a degree in natural sciences from Newnham College, Cambridge, and then enrolled for a PhD in physical chemistry under Ronald George Wreyford Norrish, the 1920 Chair of Physical Chemistry at the University of Cambridge.

Disappointed by Norrish's lack of enthusiasm, she took up a research position under the British Coal Utilisation Research Association (BCURA) in 1942.

The research on coal helped Franklin earn a PhD from Cambridge in 1945.

Moving to Paris in 1947 as a chercheur (postdoctoral researcher) under Jacques Mering at the Laboratoire Central des Services Chimiques de l'État, she became an accomplished (and famous) X-ray crystallographer.

After joining King's College London in 1951 as a research associate, Franklin discovered some key properties of DNA, which eventually facilitated the correct description of the double helix structure of DNA.

Owing to disagreement with her director, John Randall, and her colleague Maurice Wilkins, Franklin was compelled to move to Birkbeck College in 1953.

On the day before she was to unveil the structure of tobacco mosaic virus at an international fair in Brussels, Franklin died of ovarian cancer at the age of 37 in 1958.

Franklin is best known for her work on the X-ray diffraction images of DNA while at King's College London, particularly Photo 51, taken by her student Raymond Gosling, which led to the discovery of the DNA double helix for which Francis Crick, James Watson, and Maurice Wilkins shared the Nobel Prize in Physiology or Medicine in 1962.

Watson suggested that Franklin would have ideally been awarded a Nobel Prize in Chemistry, along with Wilkins but it was not possible because the pre-1974 rule dictated that a Nobel prize could not be awarded posthumously unless the nomination had been made for a then-alive candidate before Feb 1st of the award year and Franklin passed away a few years before 1962 when the discovery of the structure of DNA was recognized by the Nobel committee.

Working under John Desmond Bernal, Franklin led pioneering work at Birkbeck on the molecular structures of viruses.

Her team member Aaron Klug continued her research, winning the Nobel Prize in Chemistry in 1982.

Franklin was born in 50 Chepstow Villas, Notting Hill, London, into an affluent and influential British Jewish family.
