Rosalind Emily Franklin (1920‑1958) was a British chemist and X‑ray crystallographer whose precision and ingenuity unveiled the double‑helix structure of DNA. Her pioneering work on viruses, coal, and biological macromolecules earned her worldwide acclaim—though her most celebrated contribution came posthumously, as her diffraction images formed the backbone of the DNA model that revolutionised biology.
After graduating from Cambridge, Franklin worked on the structure of the tobacco mosaic virus and then joined the Atomic Energy Research Establishment to investigate the structure of the coal. Her meticulous methods set new standards for X‑ray crystallography.
In 1951, Franklin took over the DNA project at King’s College. Her landmark diffraction pattern, “Photo 51,” revealed the helical nature of DNA and became the cornerstone of the double‑helix model developed by Watson, Crick, and Wilkins.
Although Franklin never received a Nobel Prize, her work is now celebrated through the Rosalind Franklin Institute, the ESA’s ExoMars rover, and numerous scholarships bearing her name. Her legacy inspires scientists, particularly women in STEM, to pursue rigorous research with integrity and curiosity.
