Who contributed most to the discovery of the structure of DNA?

WEll, as I was taught, the ENTIRE credit is given to Watson and Crick for they did discover the DNA model through the earlier non-published discoveries of Rosalind Franklin. She was the one who made the entire head start and gained the most terrain regarding the discovery of DNA structure, but she didn't publish it. So, when Watson and Crick saw her discovery, they adjusted it to their model and discovered the double helix shape of the human DNA molecule. Watson and crick had this black and white sort of x-ray where an indistinct shape was portrayed. When they got Rosalind's findings, they found the way to prove the double-helix shape.
