HER BACKGROUND Rosalind Franklin was born in England into an wealthy and powerful British- Jewish family. Her uncle was Herbert Samuel (later Viscount Samuel) who was Home Secretary in 1916 and the first practicing Jew to serve in the British Cabinet. He was also the first High Commissioner (successfully director) for the British Mandate of Palestine.

Rosalind Franklin’s Early Life Born on July 25, 1920, one of five children in an well-known, fourth-generation British family, Rosalind Franklin started out simply as a girl who knew very early in life what she wanted to do as an adult. She dreamed of one day becoming a scientist, and her mother and her aunt encouraged her to follow her dream. After graduating from St. Paul's Girls School in London in 1938, Franklin studied French in Paris and then returned to England to attend Newnham College at Cambridge University.

HER BACKROUND Her aunt Helen was married to Norman Bentwich who was Attorney General in the British Mandate of Palestine. She was active in trade union organization and women's suffrage, and was later a member of the London County Council.

HER BACKROUND Franklin was educated at St Paul's Girls' School where she excelled in Latin and sport. Her family were actively concerned with a Working Men's College, where Ellis Franklin, her father, taught electricity, magnetism and the history of the Great War in the evenings and later became vice principal. Later they helped settle Jewish refugees from Europe who had escaped the Nazis.

Rosalind Franklin’s Early Life She was encouraged by physicist Adrienne Weill to follow her doctorate in chemistry, which she was awarded in While at Cambridge and then as a chemist in Paris, Franklin learned X-ray crystallography and became talented at it. Neither Rosalind Franklin nor her mentors had any idea that her work would one day change modern biology.

HER WORK Rosalind Elsie Franklin was an English physical chemist and crystallographer who made important charity to the understanding of the fine structures of DNA, viruses, coal and graphite. Franklin is best known for her work on the X- ray diffraction images of DNA which formed a origin of Watson and Crick's theory of the double helical structure of DNA in their 1953 publication, and when published constituted important proof of the theory.

X-RAY In May of 1952, working alone, Franklin photographed DNA in two forms: a "dry" form and a "wet" form (also known as the "B form"). Her clear X-ray photograph of the wet form of DNA was new. "No one had photographed the wet form before. Franklin's X-ray was amazing because she took the photograph looking down the long DNA molecule. She established that the formation of the DNA molecule was a helix, or twisted ladder, because her photographic view down the centre of the molecule showed an X. Forty-six years after James Watson viewed Franklin's startling photograph, he still recalled it brightly: "I was shown Rosalind Franklin's X-ray photograph, and whoa! It was a helix! And a month later, we had the structure. Franklin stored her X-ray photograph of the wet form of the DNA molecule in her drawer in her laboratory. Unbeknownst to Franklin, Maurice Wilkins, worried with preventing Franklin from getting ahead of him in her research, began to secretly copy her work when she was absent from the lab, and he concealed these copies of her private work in his drawer, without her knowledge.

X-RAY It was a helix! And a month later, we had the structure. Franklin stored her X-ray photograph of the wet form of the DNA molecule in her drawer in her laboratory. Unbeknownst to Franklin, Maurice Wilkins, worried with preventing Franklin from getting ahead of him in her research, began to secretly copy her work when she was absent from the lab, and he concealed these copies of her private work in his drawer, without her knowledge.

HER DEATH Franklin died of ovarian cancer on April 16, 1958, when she was just thirty-seven years old. The New York Times praised her as being one of "a select band of pioneers." She died four years before James Watson, Francis Crick, and Maurice Wilkins received the Nobel Prize for Medicine for their discovery of the structure of DNA. In an ironic twist of fate, several years before her death Franklin became friendly with Francis Crick and his wife. During her illness, Franklin even stayed as a guest in Crick's home. After her death, when Crick was "asked whether, then, he believed that no one at King's would ever have solved the problem [of the structure of DNA], Crick said, 'Oh, don't be silly. Of course Rosalind would have solved it...With Rosalind it was only a matter of time. Although during their years in Randall's laboratory at King's College Rosalind Franklin and Maurice Wilkins often behaved like enemies, twelve years after Franklin's death Wilkins in effect apologized for passing on her photographs and data to Watson without her permission.

CONCLUSION In Watson's own words recorded in 1999, "Rosalind's X- ray work...was the proof that it was right. It is not too late to set the record straight. It is important from a historical standpoint to recognize Rosalind Franklin's enormous contribution to the revolutionary discovery of DNA, not only because of its objective truth, but also as an example for all present and future female students and scientists. "To rearrange a universe is creativity enough for anyone short of God, and this is very close to what they did. If Rosalind Franklin had been given the proper recognition for her part in the discovery of the structure of DNA, science classes today would properly refer to Watson, Crick, Wilkins and Franklin, who, together, deserve recognition for the revolutionary discovery of the molecule's structure.

CONCLUSION Because the Nobel Prize is only given to living persons, and it has never gone to more than three people for one award, Rosalind Franklin posed no threat to Watson, Crick and Wilkins when they shared the award for Medicine in For Rosalind Franklin had died in But it would have been polite and extremely just for them to have credited her "famous X-ray photograph of the DNA molecule with helping to unlock the secret of the human gene. In Watson's own words recorded in 1999, "Rosalind's X-ray work...was the proof that it was right. It is not too late to set the record straight. It is important from a historical standpoint to recognize Rosalind Franklin's enormous contribution to the revolutionary discovery of DNA, not only because of its objective truth, but also as an example for all present and future female students and scientists. "To rearrange a universe is creativity enough for anyone short of God, and this is very close to what they did. If Rosalind Franklin had been given the proper recognition for her part in the discovery of the structure of DNA, science classes today would properly refer to Watson, Crick, Wilkins and Franklin, who, together, deserve recognition for the revolutionary discovery of the molecule's structure.

Our Point of View She found the x-ray photo of the DNA double helix and her effort to science was great as a woman scientist. After the death, James Watson and Frances Crick took the photograph of the x-ray that she found and told to the whole world that he found the structure of the double helix. They received the Nobel prize for this. After nearly 13 years from this, they told the truth.
