James Watson

In 1953, an earnest and ambitious 25-year-old scientist nmaed James Watson made a groundbreaking discovery that helped revolutionize science, medicine, even the law.

Working alongside Francis Crick, Watson identified the double-helix structure of DNA.

That breakthrough earned Watson and Crick the Nobel Prize in medicine in 1962. Watson wrote a book explaining the double helix.

I met him in 2002, when he published another book, which he called "enes, Girls, and Gamow." That was a reference to George Gamow, a pioneering theoretical physicist who contributed to, and built on, Watson and crick's work.
