Watson and Crick
The first picture and model of the DNA structures were made from Rosalind Elsie Franklin. Over the years William Watson and Francis Crick stole the idea from her and worked out the structure of DNA as if they invented it.
F, Crick and j.Watson discovered the structure of DNA.

Rosalind Franklin did not discover DNA. DNA was discovered long before she photographed the images via X-ray crystallography. With the help of these images, Watson and Crick were able to figure out the structure of the nucleic acid in 1953. Watson and Crick did not discover DNA either; they developed the concept of the "double helix," which was accepted as the structure of DNA.

The discovery of the structure of DNA was a culmative effort. After the discovery that the genes were paired, Watson and Crick suggested the first accurate model of DNA structure in the journal of Nature.
KEY FACT In 1953, James Watson and Francis Crick put forward their hypothesis that DNA had a double helix structure. Their first attempt to identify the structure of DNA was not successful, however, in 1953 they put forward their hypothesis that DNA had a double helix structure.

Wilkins' X-ray diffraction showed a regular, cyrstal-like structure of DNA. It was when Watson first saw Wilkins' work that his interest in DNA was sparked. Their work overlapped and complemented each other - so differences are difficult to pinpoint.
