The codécouvreuse of DNA was stolen work and a Nobel Prize. A Google Doodle begins his rehabilitation. Portrait of a scientific forgotten.
France is Marie Curie, who discovered radium and polonium in the early twentieth century, before disappearing prematurely in July 1934 after a prolonged exposure to radioactive elements. The Marie Curie English called Rosalind Franklin! This British molecular biologist involved in the discovery of the DNA structure. In 1951, stationed at King’s College London, it applies the X-ray diffraction to the study of biological materials. She made several X-ray radiographs of the DNA, which will be shown without his knowledge to James Watson and Maurice Wilkins. These photographs are instrumental in the discovery of the double helix structure of DNA by James Watson and Francis Crick in 1953. The discovery of the structure of DNA allows Watson, Crick and Wilkins received the Nobel Prize for Medicine in 1962. Unfortunately, the woman who just arrived had died four years earlier of ovarian cancer, probably caused by overexposure to radiation she us ed to make his remarkable photographs X-ray She could not share this prestigious award.
It flew its discovery by three men
The three explorers were careful to associate their colleague in their glory. Admittedly, pure product of both the high Jewish bourgeoisie English, intellectual and commercial, and the University of Cambridge, Franklin had everything to annoy. Very talented and very bright, she had experimental rigor deep in the body. With a strong character and honesty that nothing could be faulted, she preferred to retain in its records his discoveries and photographs rather than risking to communicate. It ruined the research undertaken in the Cavendish Laboratory in Cambridge competitor Watson and Cricks, which she did not understand, in its experimental rigor, the willingness to propose a theoretical three-dimensional model of the structure of DNA. She had then not yet entered the race for one of the greatest discoveries of the century was open and she held key elements. Having made common cause, future Nobel Prize-winning procure unbeknownst to the woman one of his best shots. Armed with an unpublished report which hypothesizes the famous helical structure of DNA, the trio completes the model and pull the chestnuts out of the fire with a resounding publication in the journal Nature …
A Doodle for the glory
Ten years after the death of Rosalind Franklin, Watson won the “Nobel boorishness” immortalizing in his bestseller double helix , the ” Rosie terrible “in the guise of an ugly hag and incompetent. Last year, the 50th anniversary of the discovery of the structure of DNA, the documentary legend Gary Glassman chips away by returning to its rightful place the work of Rosalind Franklin. The British scientific community and some feminists seem determined to get her out of his relative anonymity. Thursday, July 25, 2013, to celebrate her birthday (she was born July 25, 1920 in Notting Hill, London), Google it devotes one of its famous Doodle to draw attention to its hundreds of millions of users around the world on this misunderstood genius and robbed. France is also not foreign to the birth of this little-known talent. Rosalind Franklin worked in France from 1947 to 1950 at the Central Laboratory chemical services of the State, where she learned the techniques of X-ray diffraction
But the French chivalry is not a boast! Marie Curie came to the Pantheon in 1995. Today she is the only woman to be entered in its merits. Historians and scientists have made it the place it deserves. For once, the English gentlemen, it is we who fired first …
