Rosalind Franklin was born in 1920 and studied Natural Sciences. After working in Paris at the Laboratoire Central - where she became an x-ray crystallographer - she moved to King's College London. Here she helped to take the famous Photograph 51 which led to the discovery of the double helix shape of DNA.
