* Rosalind Franklin: Her X-ray diffraction images of DNA, known as "Photo 51," provided crucial evidence for the double helix structure.
* Maurice Wilkins: He worked with Franklin and provided Watson and Crick with access to her data.
* Erwin Chargaff: His research on the ratios of nitrogenous bases in DNA (Chargaff's rules) helped guide Watson and Crick's model.
* Linus Pauling: He proposed a triple helix structure for DNA, which was incorrect but inspired Watson and Crick to explore alternative possibilities.
While Watson and Crick ultimately received the Nobel Prize for their discovery, it was a collaborative effort that involved many talented scientists.
