Rosalind Franklin (1920 - 1958) was a British physicist and X-ray crystallographer who made critical contributions to the understanding of the fine molecular structures of DNA, RNA, viruses. Unpublished drafts of her papers (written just as she was arranging to leave King&#x27;s College London) show that she had independently determined structure of the DNA helix. Watson &amp; Crick received the Nobel Prize in medicine in 1962 for this work, four years after Franklin’s death of ovarian cancer.
