Rosalind Franklin, born on July 25, 1920, in London, England, was a pioneering British chemist and X-ray crystallographer whose work was crucial in understanding the molecular structures of DNA, RNA, viruses, coal, and graphite. Best known for her critical contributions to the discovery of the DNA double helix, Franklin's meticulous research and the famous "Photo 51" provided key insights that were instrumental in revealing the helical structure of DNA. Despite her significant achievements, her contributions were often overlooked during her lifetime. Franklin's dedication to science and her groundbreaking work have earned her a lasting legacy as one of the most important figures in molecular biology. She passed away on April 16, 1958, but her contributions continue to inspire and influence the scientific community.
