James Watson, the scientist who co-discovered the structure of DNA, died on Nov. 6, 2025, at the age of 97. Watson, along with Francis Crick and Maurice Wilkins, won the Nobel Prize for their groundbreaking work on DNA’s double helix structure. This discovery revolutionized medicine and biology, influencing fields like crime-fighting and genealogy. Watson’s career was marked by significant achievements, including his role in mapping the human genome. However, his legacy is complicated by controversial remarks on race, which led to his condemnation and loss of honorary titles. His contributions to science remain influential.
