Francis Crick and James Watson
DNA (deoxyribonucleic acid) appears likely to have evolved from the much simpler molecule, RNA. Of course, DNA was not the only possible direction in which evolution could have taken, but it has proven to be a very successful one.
DNA was first discovered back in 1869 by Johann Friedrich Miescher. The fundamental structure of DNA was discovered by James Watson and Francis Crick, although many people believe that Rosalind Franklin also played a large role in their research.
Simple Answer:
James Watson and Francis Crick are credited with the first correct double-helix model of DNA structure published in 1953 in the journal Nature.
More Complicated:
Credit for the research leading to the discovery of the structure of DNA is controversial. The publication by Watson and Crick was based on an x-ray image taken by Rosalind Franklin and Raymond Gosling in May 1952. A critical problem in an earlier model was corrected based on private communications from Erwin Chargaff.
Several critical publications occurred at almost the same time. A separate paper by Franklin and Gosling's provided the X-ray diffraction data and original analysis method for the Watson and Crick model. Maurice Wilkins also published X-ray patterns also supporting a double-helix molecular model of DNA.
Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine in 1962 but since this was after Franklin's death, it is often assumed that Franklin would have also shared the prize is she had lived.

(James) Watson and Crick. Actually, a lady X-ray crystallographer got 'er done before they did but that's another story.
Watson and Crick
The Nobel Prize in Physiology or Medicine 1962 was to Francis Harry Compton Crick, James Dewey Watson and Maurice Hugh Frederick Wilkins for work on DNA. However, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher. Then other scientists: Phoebus Levene and Erwin Chargaff added to the basis of this knowledge.
Phoebus Levene and Erwin Chargaff- carried out a series of research efforts that revealed details about the DNA molecule, including its primary chemical components and the ways in which they joined with one another.
Without the scientific foundation provided by these pioneers, Watson and Crick may never have reached their groundbreaking conclusion of 1953: that the DNA molecule exists in the form of a three-dimensional double helix.
The two scientists who have been recognized as discovering the structure of DNA (deoxyribonucleic acid) are James D. Watson and Francis Crick.

Rosalind Franklin was an expert in x-ray crystallography who is famous for her x-ray diffraction images of DNA. Watson and Crick, who are commonly credited with the discovery of the structure of DNA, have admitted that Franklin's data played an integral part in their discovery of the double helix model of DNA. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine in 1962 but since this was after Franklin's death, it is often assumed that Franklin would have also shared the prize is she had lived.

In 1953, James Watson and Francis Crick discovered the structure of DNA. This was the second great discovery of genetics.
James Watson, and Francis Crick
Watson and Crick and credited with discovering the structure of DNA. They mapped out how the bases pair up. Adenine bonds with thymine, and cytosine with guanine.
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.
