Rosalind Franklin (1920-1958)

I did an open thread again today at My Left Wing. Since the tradition is to show a picture of someone who was born on the day (or occasionally someone who died on the day), this give me the opportunity to learn about people I didn't know about before. Today it's Rosalind Franklin.

Rosalind Franklin, born July 25, 1920

From the Rosalind Franklin Papers:
...a British chemist and crystallographer who is best known for her role in the discovery of the structure of DNA. It was her x-ray diffraction photos of DNA and her analysis of that data--provided to Francis Crick and James Watson without her knowledge--that gave them clues crucial to building their correct theoretical model of the molecule in 1953. While best known for this work, Franklin also did important research into the micro-structure and properties of coals and other carbons, and spent the last five years of her career elucidating the structure of plant viruses, notably tobacco mosaic virus.
