James Watson, who passed away at the age of 97, was pivotal in the discovery of DNA's structure, a landmark achievement in the 20th century. Alongside Francis Crick, Watson unveiled the double helix model of DNA at Cambridge University in 1953.

This discovery revolutionized the understanding of genetics, establishing that DNA encodes genetic information using a chemical alphabet of four nucleotides: adenine, thymine, guanine, and cytosine. Their findings suggested a copying mechanism for genetic material, which laid the groundwork for advancements in evolutionary biology, medicine, and forensic science.

Watson's memoir, The Double Helix, provided a dramatic account of their race to unveil the genetic code, though it was not without controversy, as he often expressed disdain for his contemporaries. Watson's early academic journey began at the University of Chicago, where he developed an interest in genetics, leading him to work under notable scientists like Hermann Muller.

His research took him to the Cavendish Laboratory, where he collaborated with Crick, both driven by the conviction that DNA was the key to genetic inheritance. Their approach involved building physical models based on X-ray diffraction data, ultimately leading to their groundbreaking publication in Nature.

The pair, along with Maurice Wilkins, were awarded the Nobel Prize in 1962 for their contributions. Watson's later career included leadership roles in significant projects like the Human Genome Project, aimed at mapping the entire human genome, a venture that advanced genetic research significantly.

The project faced skepticism but eventually led to breakthroughs in genomics and bioinformatics. However, Watson's legacy is marred by controversies arising from his personal views on intelligence and race, which led to his resignation from prestigious positions.

His remarks sparked backlash, culminating in the revocation of his honorary titles from Cold Spring Harbor Laboratory. Despite these controversies, Watson's contributions to molecular biology and genetics have had an enduring impact, shaping modern biotechnology and medicine.

Watson is survived by his wife Elizabeth, their sons, and a grandson.
