James Watson, Co-discoverer of DNA's Double-Helix, Has Died

James Watson, who helped uncover the twisted-ladder structure of DNA in 1953, has passed away, according to his former research laboratory. Born in Chicago, Watson was only 24 when he made this groundbreaking discovery that revolutionized medicine, forensic science, genealogy, and ethics.

Nobel Prize and Scientific Impact

Watson was one of three recipients of the 1962 Nobel Prize in Physiology or Medicine, alongside Francis Crick and Maurice Wilkins, honored for showing that DNA consists of two strands coiling around each other in a double helix. This structure revealed how genetic information is stored and explained the mechanism by which cells replicate DNA during division.

“The duplication begins with the two strands of DNA pulling apart like a zipper.”

The double helix became an iconic symbol of science, recognized by the general public and depicted in art and popular culture, including works by Salvador Dali and British postage stamps.

Controversies Later in Life

Despite his monumental contributions to science, Watson faced significant backlash and professional condemnation toward the end of his life. He was criticized for making racist remarks, including claims that Black people are less intelligent than white people.

Watson faced condemnation and professional censure for offensive remarks, including saying Black people are less intelligent than white people.

Legacy

Watson's discovery transformed biology and medicine, but his later statements have complicated his legacy.

Summary: James Watson’s discovery of DNA’s double helix revolutionized science and medicine, but his legacy is marred by controversial, offensive remarks late in life.
