Whose work revealed the double helix of DNA?

In 1953, James Watson and Francis Crick published their model of DNA as a double helix — two strands twisted around each other like a spiral ladder. Their breakthrough relied heavily on the X-ray diffraction images produced by Rosalind Franklin, whose contribution was long under-recognised. Understanding this structure revealed how genetic information is stored and copied, launching the era of modern molecular biology and genetics. Watson, Crick, and Maurice Wilkins received the Nobel Prize in 1962; Franklin had died by then.
