James Watson, Co-Discoverer of DNA’s Double Helix, Dies at 97

James D. Watson, the American biologist renowned for co-discovering the double-helix structure of DNA, passed away on November 6, 2025, at the age of 97. He died in hospice care on Long Island, New York.

Early Life and Groundbreaking Discovery

Born in Chicago in 1928, Watson exhibited exceptional scientific aptitude from a young age. In 1953, at just 24, he collaborated with Francis Crick to unveil the double-helix structure of deoxyribonucleic acid (DNA). This pivotal discovery elucidated how genetic information is stored and replicated, revolutionizing the field of molecular biology. The duo, along with Maurice Wilkins, received the Nobel Prize in Physiology or Medicine in 1962 for their work.

Contributions to Science and Leadership

Beyond the DNA discovery, Watson played a significant role in advancing genetics and molecular biology. He served as the first director of the Human Genome Project in 1990, overseeing efforts to map the entire human genome. Additionally, he transformed Cold Spring Harbor Laboratory into a leading research institution during his tenure as director and president.

Controversies and Later Years

Despite his scientific achievements, Watson’s later years were marred by controversy. He made several public statements suggesting a link between race and intelligence, leading to widespread condemnation. In 2007, these remarks resulted in his resignation from Cold Spring Harbor Laboratory and the revocation of honorary titles. In 2019, he reiterated these views in a documentary, further isolating him from the scientific community.

Legacy

James Watson’s contributions to science are monumental, laying the foundation for modern genetics and biotechnology. However, his legacy is complex, intertwined with both groundbreaking discoveries and contentious viewpoints. He is survived by his sons, Rufus and Duncan, and will be remembered as a figure who profoundly influenced science while sparking significant ethical debates.
