Born in London, Rosalind Franklin's work was crucial in discovering the structure of DNA. In 1946, Franklin moved to Paris where she perfected her skills in X-ray crystallography, which would become her life's work. Although she liked Paris, she returned after four years to London to accept a job at King's College.
Unknown to Franklin, her colleagues at King's College, Watson and Crick duplicated some of her unpublished data, including the beautiful "photo 51". This X-ray diffraction picture of a DNA molecule leveraged Watson's career. Using Franklin's photograph and their own data, Watson and Crick created their famous DNA model. Franklin's contribution was not acknowledged, but after her death Crick said that her contribution had been critical. In fact, even the Nobel Committee acknowledged Watson and Crick's claims but failed to recognize Franklin's contribution.
Franklin's life was cut short by ovarian cancer and she died at 37.
Here is a video on Rosalind Franklin referred to as the "Dark Lady of DNA".
