Rosalind Franklin
Watson and Crick built a DNA model in the shape of a double helix, which resembles a twisted ladder. The double helix structure of DNA consists of two strands that are twisted around each other to form a stable and efficient way to store genetic information.
James D. Watson and Francis Crick proposed the double helix structure of DNA in 1953. It was based from an x-ray diffraction image taken by Rosalind Franklin and Raymond Gosling and information on how the bases paired, which was acquired from Erwin Chargaff. Maurice Williams belongs here as well
The first correct shape was the double helix by Watson and Crick. However, there were earlier incorrect models, for example the incorrect triple helix model proposed by Linus Pauling. Even the first model by Watson and Crick turned out to be incorrect; they had it inside out compared to the correct model.
Watson & Crick constructed the very first model of DNA :) is that what you were looking for ?
In 1953, James Watson and Francis Crick proposed a double helix model of DNA, which consists of two intertwined strands that run in opposite directions. This model explained how genetic information is stored and transmitted in living organisms.

James Watson and Francis Crick are credited with the first accurate model of DNA's molecular structure in 1953. Their double helix model of DNA paved the way for groundbreaking discoveries in genetics and molecular biology.
Crick and Watson have always been very open about the fact that they used Rosalind Franklin's x-ray data to deduce the double helix model of DNA.
Watson and Crick used a double helix model to describe the structure of DNA. This model consists of two strands that twist around each other in the shape of a helix, with nucleotide bases forming pairs between the two strands.
