Rosalind Franklin
Rosalind Franklin was a British chemist and X-ray crystallographer whose research produced crucial imaging evidence for the discovery of DNA's double-helix structure, though her contributions were long underrecognized.
An X-ray image she produced became the missing piece in solving DNA's structure, yet it was shared with rival scientists without her knowledge, and she died years before a Nobel Prize was ever awarded for the discovery.
A Skilled Experimentalist
Franklin was an exceptionally skilled experimental scientist who used X-ray diffraction techniques to capture detailed images of DNA fibers, work requiring extraordinary technical precision and patience with the imaging equipment of the era.
Photograph 51
Franklin's most significant contribution was an image known as "Photograph 51," which revealed the helical structure of DNA with striking clarity, providing crucial visual evidence of the molecule's now-famous double-helix shape.
Data Shared Without Consent
Franklin's data and images were shown to competing researchers James Watson and Francis Crick without her knowledge or consent by a colleague, and this information proved instrumental in their subsequent published model of the DNA double helix in 1953.
Recognition Denied
Watson, Crick, and Maurice Wilkins (who had shared Franklin's work) were awarded the Nobel Prize for the DNA discovery in 1962, a prize Franklin could not share, as Nobel Prizes are not awarded posthumously and she had died several years earlier.
Posthumous Recognition
Franklin died of ovarian cancer in 1958 at just 37 years old. In recent decades, she has received growing and much-deserved recognition for her essential, long under-credited role in one of the most important discoveries in the history of biology.
