The book describes how, over three years, teams led by physicist Charles Townes (inventor of the maser, the laser's microwave predecessor) and doctoral student Gordon Gould sought to be the first to extend the physical principles used in the maser to the realm of light amplification, only to be beaten out by Ted Maiman, a little known physicist from California, inventor of a small device that was the first working ruby laser.
Once Maiman's ruby laser was announced at a press conference in July 1960, teams working on lasers across the country started making progress quickly and by the end of the year, three different types of laser had been demonstrated.
