Reevaluating Rosalind Franklin's Impact on the Discovery of DNA's Structure.

Two scientists have uncovered more details about Rosalind Franklin's contribution to the discovery of DNA's double helix in an overlooked letter and an unpublished news article from the 1950s. Franklin 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. Franklin wasn't a naive outsider following her own path. The discovery of DNA's structure was the product of two teams who often cross-checked their work.

Revisiting Rosalind Franklin's Contribution to DNA Discovery.

Two historians suggest that Rosalind Franklin, an expert in X-ray imaging, was more a collaborator than just a victim in the discovery of DNA's double helix structure. While James Watson and Francis Crick did rely on research from Franklin and her lab without their permission, the historians found new details that challenge the simplistic narrative that Watson and Crick stole data from Franklin. The historians suggest that Franklin contributed more than just one photograph along the way and that the four researchers were equal collaborators in the work.

Revisiting Rosalind Franklin's Contribution to DNA Discovery.

Researchers argue that the popular narrative of Rosalind Franklin's X-ray diffraction image, Photo 51, being illicitly shown to James Watson, revealing to him that DNA has a double helix and allowing him and his colleague Francis Crick to deduce the structure and claim the glory, is far from the key to the puzzle. Instead, the success of Watson and Crick was down to trial and error with calculations and cardboard models, with the importance of Photo 51 augmented by Watson in his 1968 book, The Double Helix, to add drama to the tale of the discovery.

Revisiting Rosalind Franklin's Contribution to DNA Discovery

The discovery of the structure of DNA by James Watson and Francis Crick 70 years ago was a major milestone in science, but it has long been suspected that they robbed Rosalind Franklin of her contribution to the discovery. Franklin's famous photo 51 was used by Watson and Crick to find DNA's structure, but it was obtained without her knowledge. Franklin was also given insufficient credit for her work. While some argue that the situation was complex, it is clear that Franklin was robbed of her contribution to the discovery.

Revisiting Rosalind Franklin's Contribution to DNA Discovery

A new opinion essay published in Nature argues that Rosalind Franklin, the British chemist and crystallographer, was an "equal contributor" to the discovery of the double helix structure of DNA, rather than a victim of scientific misconduct. The essay draws upon two previously overlooked documents in Dr. Franklin's archive, which suggest that she knew that James Watson and Francis Crick had access to her data and that she and Maurice Wilkins collaborated with them. However, the essay does not change the fact that Dr. Franklin did not receive adequate recognition for her work.
