Francis Crick: Discoverer of the Genetic Code (Eminent Lives) : Francis Crick, who died at the age of eighty-eight in 2004, will be bracketed with Galileo, Darwin, and Einstein as one of the great scientists of all time. Between 1953 and 1966 he made and led a revolution in biology by discovering, quite literally, the secret of life: the digital cipher at the heart of heredity that distinguishes living from non-living things - the genetic code. His own discoveries - though he always worked with one other partner and did much of his thinking in conversation - include not only the double helix but the whole mechanism of protein synthesis, the three-letter nature of the code, and much of the code itself. Matt Ridley's biography 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. While at Cambridge, he suddenly began to display the unique visual imagination and intense tenacity of thought that would allow him to see the solutions to several great scientific conundrums - and to see them long before most biologists had even conceived of the problems.
