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. Her contribution was famously and disgracefully downplayed by the men who won the Nobel Prize. Later at Birkbeck College she undertook pioneering work of the structure of viruses before dying of ovarian cancer, aged just 37.
