How old would James Watson be today?

James Dewey Watson was an American molecular biologist, geneticist, and zoologist. In 1953, James Watson and Francis Crick co-authored an academic paper on DNA entitled, "Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid". Published in the scientific journal Nature, the paper proposed the existence of the double helix structure of the DNA molecule, having built on research by Rosalind Franklin and Raymond Gosling. In 1962, the Nobel Prize in Physiology or Medicine was awarded to James Watson, Francis Crick, and Maurice Wilkins "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".
