Hughes presents a history of the American genius for invention and technology, and argues that inventors, industrial scientists, engineers, and designers have been the makers of the first technological nation. He delves into the motivations and methods of the creative person, and traces the evolution of invention, how its practice changed as its locale shifted from inventor's workshop to the industrial research laboratory, business corporation, and the military-industrial complex. He also covers the culture of technology: how order, system, and control have become values whose influence extends beyond technology; the Soviet Union's exploitation of America's know-how, especially in scientific management; and the disappointments with technology as articulated by Lewis Mumford, Jacques Wllul, and Henry Marcuse.
