Francis Crick--the quiet genius who led a revolution in biology by discovering, quite literally, the secret of life--will be bracketed with Galileo, Darwin, and Einstein as one of the greatest scientists of all time. In his fascinating biography of the scientific pioneer who uncovered the genetic code-the digital cipher at the heart of heredity that distinguishes living from non-living things-acclaimed bestselling science writer Matt Ridley traces Crick's life from middle-class mediocrity in the English Midlands through a lackluster education and six years designing magnetic mines for the Royal Navy to his leap into biology at the age of thirty-one and its astonishing consequences. In the process, Ridley sheds a brilliant light on the man who forever changed our world and how we understand it.
