![]() "Her photographs were among the most beautiful X-ray photographs of any substance ever taken. "As a scientist Miss Franklin was distinguished by extreme clarity and perfection in everything she undertook," he said. John Desmond Bernal, one of the United Kingdom’s most well-known and controversial scientists and a pioneer in X-ray crystallography, spoke highly of Franklin around the time of her death in 1958. The photo was acquired through 100 hours of X-ray exposure from a machine Franklin herself had refined. One of their X-ray diffraction pictures of the "B" form of DNA, known as Photograph 51, became famous as critical evidence in identifying the structure of DNA. Studying DNA structure with X-ray diffraction, Franklin and her student Raymond Gosling made an amazing discovery: They took pictures of DNA and discovered that there were two forms of it, a dry "A" form and a wet "B" form. In January 1951, Franklin began working as a research associate at the King's College London in the biophysics unit, where director John Randall used her expertise and X-ray diffraction techniques (mostly of proteins and lipids in solution) on DNA fibers. DNA, Scientific Discoveries and Credit Controversy In addition, Franklin pioneered the use of X-rays to create images of crystallized solids in analyzing complex, unorganized matter, not just single crystals. He taught her X-ray diffraction, which would play an important role in her research that led to the discovery of "the secret of life"-the structure of DNA. In the fall of 1946, Franklin was appointed at the Laboratoire Central des Services Chimiques de l'Etat in Paris, where she worked with crystallographer Jacques Mering. thesis "The physical chemistry of solid organic colloids with special reference to coal." She went on to work as an assistant research officer at the British Coal Utilisation Research Association, where she studied the porosity of coal-work that was the basis of her 1945 Ph.D. In 1941, she was awarded Second Class Honors in her finals, which, at that time, was accepted as a bachelor's degree in the qualifications for employment. She received her education at several schools, including North London Collegiate School, where she excelled in science, among other things.įranklin enrolled at Newnham College, Cambridge, in 1938 and studied chemistry. She displayed exceptional intelligence from early childhood, knowing from the age of 15 that she wanted to be a scientist. Rosalind Elsie Franklin was born into an affluent and influential Jewish family on July 25, 1920, in Notting Hill, London, England. ![]() Franklin died of ovarian cancer in 1958, at age 37. Other scientists used it as evidence to support their DNA model and took credit for the discovery. One of her photographs provided key insights into DNA structure. She learned crystallography and X-ray diffraction, techniques that she applied to DNA fibers. in physical chemistry from Cambridge University. ![]()
