Rosalind Elsie Franklin: March 21

Rosalind Elsie Franklin was a British biophysicist and X-ray crystallographer who made critical contributions to the understanding of molecular structures. Franklin is best known for her work on the X-ray diffraction images of DNA which led to the discovery of the double helix. Her data, according to Francis Crick, were the data we used to formulate Crick and Watson’s 1953 hypothesis regarding the structure of DNA. Franklin was never nominated for a Nobel Prize. The rules forbid posthumous nominations and because she had died in 1958, she was not eligible for nomination to the Nobel Prize subsequently awarded to Crick, Watson, and Wilkins in 1962.
