The double helical model of DNA was first constructed by:
Watson and Crick
The now well-known DNA double helical model was first constructed by James Watson and Francis Crick in the year 1953 at Cambridge University, England. They built on their work as well as critical data from Rosalind Franklin’s X-ray diffraction experiments on DNA and previous work done by Crick with another collaborator Maurice Wilkins at King’s University, London. For their discovery that they self-proclaimed as one that unlocked ‘the secrets of life’, Watson and Crick together with Wilkins were awarded the Nobel Prize in Chemistry in the year 1962. Rosalind Franklin unfortunately passed away in 1958, and since the prize isn’t awarded posthumously, to this day, she remains largely unrecognized for her contribution to this discovery.
