Rosalind Franklin

Rosalind Franklin (July 25, 1920 – April 16, 1958) was a British-Jewish chemist and crystallographer whose meticulous X-ray crystallography work provided critical evidence for understanding the structure of DNA. Her famous 'Photo 51,' taken in 1952, provided the clearest evidence for the helical structure of DNA, yet this work was shared without her knowledge or consent with James Watson, who later used it in his collaborative work with Francis Crick and Maurice Wilkins. Though Watson, Crick, and Wilkins received the Nobel Prize in Physiology or Medicine in 1962 for the DNA structure discovery, Franklin had died in 1958 and could not be recognized (the Nobel Prize is not awarded posthumously). Franklin was also a pioneering researcher in RNA structure and viruses. Despite the initial lack of recognition, she was a meticulous scientist, excellent teacher, and mentor to younger researchers. In recent decades, her crucial contributions have been properly acknowledged, and she has become an iconic figure in discussions of women in science and the history of scientific achievement. Franklin's legacy includes not only her scientific discoveries but her role in highlighting gender inequities in science and the importance of crediting all contributors to scientific breakthroughs.
