English crystallographer hired by Wilkins to study DNA. She recognized the A and B forms of DNA, and discovered that the phosphate group must lie on the outside of the structure. Franklin performed X-ray diffraction studies which showed James Watson and Crick's original model to be wrong. Franklin and Wilkins demonstrated that the double helix model later found to be correct was consistent with the data. For this work, Wilkins shared the 1962 Nobel Prize in medicine with Watson and Crick, but Franklin's contributions went largely unacknowledged.
