Which scientist’s research was pivotal for Watson and Crick's discovery of DNA structure?

The research of Rosalind Franklin was crucial for Watson and Crick's discovery of the DNA structure due to her pioneering work with X-ray crystallography. Franklin captured highly detailed images of DNA, notably the famous Photo 51, which provided vital information about the helical structure of DNA. Her images revealed dimensions and the helical shape of DNA, contributing significantly to the understanding of its double helix structure. Watson and Crick used these insights to model DNA’s structure accurately, further solidifying their groundbreaking model. Franklin's meticulous research and findings laid the groundwork that enabled Watson and Crick to formulate their hypothesis about DNA's structure.
