When Watson and Crick described the structure of DNA, none of the 16 people on the following pages had been born. Nine years later, when Watson, Crick, and Wilkins won the Nobel Prize, these 16 still weren’t born. When Lee Hood invented the automated sequencer, none of them had taken high-school biology yet. When the Human Genome Organization was established, many of them were home playing computer games. Same goes for the year Amgen was founded and the year Kary Mullis invented PCR.
