Happy Birthday Rosalind Elsie Franklin

Rosalind Elsie Franklin, born July 25, 1920, was a Physical chemist and crystallographer who worked on the X-ray diffraction images of DNA which formed a basis of Watson and Crick's hypothesis of the double helical structure of DNA in their 1953 publication.  When published in its own article along side Watson and Crick’s, her data constituted critical evidence of their hypothesis.  Later, she led pioneering work on the tobacco mosaic and polio viruses.
