One of the more famous images in biology is known as "Photo 51," an image of DNA that chemist Rosalind Franklin and Raymond Gosling created in 1952 by shooting X-rays through fibers of DNA and analyzing the patterns they left behind on film.X-ray diffraction image of the double helix structure of the DNA molecule, taken in 1952. The image, famously known as "Photo 51," led to greater understanding of DNA and gave rise to the field of molecular biology. Image by Raymond Gosling/King's College London
