description Rosalind Franklin Overview
Rosalind Franklin (1920-1958) was a brilliant chemist and X-ray crystallographer whose work was crucial to the discovery of the DNA structure. Her 'Photo 51,' obtained through X-ray diffraction, provided vital data that Watson and Crick used to build their model. Despite her pivotal role, Franklins contributions were largely unacknowledged during her lifetime, and her work was minimized in the initial publication. Her legacy serves as a reminder of the importance of recognizing the contributions of all scientists, particularly women in STEM.

help Rosalind Franklin FAQ
What is Photo 51?
Photo 51 is an X-ray diffraction image of DNA taken by Rosalind Franklin and her PhD student Raymond Gosling in 1952. The image provided the crucial data that revealed the double-helix structure of DNA.
Who used Rosalind Franklin's data to discover the DNA structure?
James Watson and Francis Crick used Franklin's unpublished data from Photo 51 without her direct knowledge or permission. They published their famous double-helix model in the journal Nature in April 1953.
What university did Rosalind Franklin work at when she studied DNA?
Franklin conducted her groundbreaking DNA research at King's College London. She was originally hired there to work on X-ray diffraction techniques for studying coal and later transitioned to biological molecules.
Did Rosalind Franklin win the Nobel Prize for her DNA work?
No, Rosalind Franklin did not receive the Nobel Prize because she passed away from ovarian cancer in 1958. Watson, Crick, and her colleague Maurice Wilkins were awarded the prize in 1962, which is not awarded posthumously.
