dna was discovered long back.franklin took x-ray images of dna,with the help of which watson and crick were able to break the code of its structure.
He didn't. DNA was already known before Crick, Watson, Wilkins and Franklin discovered its chemical structure in the early 50s. Crick and Watson published in "Nature" in April of 1953.
He used X-ray diffraction
Rosalind Franklin and Maurice Wilkins both gave a n x-ray of a Diffraction of a DNA Crystal
The answer (if you had formulated your question properly - where is the list of researchers you allude to?) would be Rosalind Franklin.
Together with Maurice Wilkins and Rosalind Franklin they discovered the structure of DNA.

the structure of DNA
The research of Rosalind Elsie Franklin led to the discovery of the double-helix structure of DNA. She did not actually discover DNA, but opened the way for others. She died in 1958, four years before the Nobel Prize in chemistry was awarded to her colleagues Maurice Wilkins, James Watson and Francis Crick for the discovery of the structure of DNA.

It was Maurice Wilkins and Rosalind Elise Franklin.

rosilendFranklind and wilkins were enemys franklin She took pictures of DNA using xray diffraction and discovered DNA is helical. Later Wilkins stole her pictures and used her discovery as his own. in 1958 Rosilend franklen died.and in 1962 Wilkins got a reward by using franklens picture and passing it on as his own discovery.
James Watson and Francis Crick elucidated the structure of DNA in 1953. Also useful in a sterochemical fashion was the X-ray diffraction work of Rosalind Franklin. Wilkins also contributed diffraction work.
