Biography

Rosalind Elsie Franklin was a British chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA, RNA, viruses, coal, and graphite.

How & why

Franklin, from a prominent Anglo-Jewish family in London, was an expert X-ray crystallographer whose 'Photo 51' and quantitative measurements captured the helical, dimensioned structure of DNA. Watson and Crick used her data — shown to them without her knowledge — to build the double-helix model. She died of ovarian cancer at 37, before the Nobel that recognised the discovery, and later also did pioneering work on virus structure.
