Franklin captures "Photograph 51," critical for identifying DNA's structure.
On May 1, 1952, Rosalind Franklin, along with her PhD student Raymond Gosling, captured the renowned X-ray diffraction image known as "Photograph 51" at King's College, London. This image was pivotal in revealing the double-helix structure of DNA. It demonstrated clear periodic patterns that helped define the dimensions of DNA and solidified its helical nature. This work was crucial in leading Francis Crick and James Watson to propose the DNA double-helix model.
