Seventy years ago this week, news broke that scientists had discovered the double-helical structure of DNA, revealing the genetic material that encodes all life takes the form of two twisting strands held together by chemical threads.
Instead, James Watson and Francis Crick would go on to share a Nobel Prize with Franklin's colleague Maurice Wilkins, write best-selling books, and speak at length about how they pieced together the structure of DNA using data taken from a now-iconic image known asThe picture's scatter of fuzzy dots was formed by X-rays refracting from DNA's molecular structure.
Cobb and Comfort rifled through an archive of Franklin's notes to reconstruct her ideas, outlining how the former student ofFranklin conducted many careful measurements of her X-ray diffraction images, recording her data in an informal report. On making its way into the hands of Watson and Crick, the observations were used – without permission – to validate their theoretical model of DNA.
, by casting the day he first saw Photograph 51 as a classic 'eureka moment' that readers could understand.
