Four people in England, back in 1953, stared at photo 51. it wasn’t much –a picture showing a black X. But three of these people won the Nobel Prize for figuring out what the photo really showed—the shape of DNA. The discovery brought fame and fortune to scientists James Watson, Francis crick, and Maurice Wilkins. The fourth, the one who actually made the picture, was left out.
Her name was Rosalind Franklin. “She should have been up there,” says historian Mary Bowden. “If her photo hadn’t been there, the others couldn’t have come up with the structure.” one reason Franklin was missing was that she had died of cancer four years before the Nobel decision. But now scholar doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitions.
At Cambridge University in the 1950s, Watson and Crick tried to make models by cutting up shapes of DNA’s parts and then putting them together. In the meantime, at king’s college in London, Franklin and Wilkins shone X-rays at the molecule(分子). The rays produced patterns reflecting the shape.
But Wilkins and Franklin’s relationship was a lot rockier than the celebrated teamwork of Watson and Crick. Wilkins thought Franklin was hired to be his assistant. But the college actually employed her to take over the DNA project.
What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out. And she was not shy about saying so. That angered Watson, who attacked her in return,” Mere inspection suggested that she would not easily bend. Clearly she had to go or be put in her place.
As Franklin’s competitors, Wilkins, Watson and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina Abir-Am. In 1962 at the Nobel Prize awarding ceremony, Wilkins thanked 13 colleagues by name before he mentioned Franklin. Watson wrote his book laughing at her. Crick wrote in 1974 that “Franklins was only two steps away from the solution.”
No, Franklin was the solution.” She contributed more than any other player to solving the structure of DNA. She must be considered a co-discoverer,” Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the “Dark Lady of DNA”, Franklin is finally coming into the light.

A Nobel Prize is considered by most people one of the highest international honors a person can receive. As you know, the prizes were started by a Swede called Alfred Nobel. Alfred Nobel was born in Stockholm, the capital of Sweden, and lived from 1833 to1896. Alfred Nobel was a chemist and inventor. He made two important inventions. And so he became very rich. Although he was rich, Nobel was not a happy man. He never married nor had children. Also, he was a sick man in a large part of his life. Nobel died at the age of sixty-three. When he died, he left a fund 基金) of $9,000, 000. The money was to be used in giving prizes to those who made outstanding achievements in physics, chemistry, medicine, literature and the promotion 促进)of world peace. The first Nobel Prizes were given on December 10th, 1901, five years after Nobel’s death. Many famous people from all over the world have been given Nobel Prizes for their achievements. Albert Einstein was one of them. Each Prize has three parts. The first part is a gold medal. Second, a winner of a Nobel Prize is given a diploma(证书)saying that he has been given the Prize. The third part of the prize is a large amount of money—about $40, 000. Often a Prize is given to just one person, but not always. Sometimes, a Prize is shared. It may be given to two or three people who have worked together. Sometimes a Prize is not given at all if there is no outstanding achievement. In 1972, for example, no Nobel Peace Prize was given. It is the Nobel Foundation in Stockholm that decides whether to give the Prize or not
