James D. Watson, DNA pioneer, dies aged 97

James D. Watson, the molecular biologist who helped unlock the structure of DNA, has died at the age of 97. His discovery of the famous double-helix in 1953 set the foundation for modern genetics, medicine, forensic science and genealogy. 

Born in Chicago in 1928, Watson was just 24 when alongside Francis Crick and Maurice Wilkins he revealed how two intertwined strands of deoxyribonucleic acid carry the blueprint of life. That revelation not only mapped how genes are passed from generation to generation, but also launched entire fields of research in gene therapy, DNA profiling and genome sequencing. 

Watson’s career extended far beyond that initial breakthrough. He authored influential textbooks, led the Cold Spring Harbor Laboratory and championed the ambitious Human Genome Project. Yet his legacy is complicated. In later years, Watson made several highly controversial remarks about race and intelligence, which resulted in professional sanctions and that tarnished public perception of his scientific stature. 

His death—confirmed by his former lab and announced by his son following a brief illness—marks the end of a life that bridged some of the greatest scientific milestones of the 20th century, and the ethical debates that came with them. 

Key Takeaways:

Watson’s co-discovery of the DNA double helix revolutionised genetics, medicine and forensic science.

He led major research institutions and initiatives, but his later career was overshadowed by racist comments and professional repercussions.

His passing at 97 closes the chapter on a seminal figure whose work reshaped our understanding of life and heredity.
