Rosalind Franklin: The Woman Who Revealed the Structure of DNA
Rosalind Franklin (1920–1958) was a British chemist and crystallographer whose research forever changed the history of biology. Her work with X-ray diffraction techniques provided one of the most revealing pieces of evidence about the structure of DNA, the molecule that contains the genetic information of all living beings.
After earning her Ph.D. in Physical Chemistry from Cambridge University, Franklin worked in Paris at the Laboratoire Central des Services Chimiques de l’État, where she perfected X-ray diffraction techniques applied to carbonaceous materials. In 1951, she joined King’s College London, where she began studying DNA fibers. It was there that she captured the famous Photograph 51, a highly sharp image that showed clear indications of the molecule's helical structure.
Based on that image (used without Rosalind's knowledge or authorization), James Watson and Francis Crick were able to propose the DNA double helix model, which they published in 1953 along with Maurice Wilkins. Although her contribution was essential, Franklin was not included when, in 1962, Watson, Crick, and Wilkins received the Nobel Prize in Physiology or Medicine. Her premature death at age 37, due to ovarian cancer, prevented her role from being fully recognized during her lifetime, as the Nobel Prize is not awarded posthumously.
Beyond this enormous historical injustice, Rosalind Franklin left a profound mark on science. After her time at King's College, she conducted pioneering research on the structure of viruses, such as the tobacco mosaic virus, which also contributed to the development of modern molecular biology. Today, she is remembered as a symbol of scientific rigor, determination, and the fight for equal recognition in science.
