The discovery of DNA's double helix structure is credited to James Watson and Francis Crick, who published their findings in 1953.

However, it's important to note that their discovery relied heavily on the work of other scientists:

* Rosalind Franklin produced crucial X-ray diffraction images of DNA that revealed its helical structure.

* Maurice Wilkins worked with Franklin and provided Watson and Crick with key information.

* Erwin Chargaff discovered the base pairing rules (Adenine with Thymine, and Cytosine with Guanine), which helped Watson and Crick build their model.

While Watson and Crick received the Nobel Prize for their discovery, the contributions of Franklin, Wilkins, and Chargaff are equally significant in understanding the structure of DNA.
