How did Rosalind Franklin miss the helix in her iconic DNA image? She didn't

A recent analysis challenges the long-standing historical narrative that Rosalind Franklin failed to recognize the helical structure of DNA in her famous 'Photo 51.' For decades, some historians suggested she overlooked the significance of her own X-ray diffraction data. However, new evidence indicates that Franklin was well aware of the helical nature of the molecule. Her laboratory notes and correspondence reveal that she had identified the double-helical symmetry months before the publication of the famous Watson and Crick model. This re-examination highlights the systemic biases that historically marginalized her contributions to molecular biology. By meticulously reviewing her unpublished records, researchers have confirmed that Franklin’s work was not a missed opportunity, but rather a foundational discovery that was unfairly overshadowed by the rapid publication of her contemporaries. This correction serves to restore her legacy as a primary architect of the discovery of DNA's structure.
