Book excerpt: The Pulitzer Prize-winner’s classic account of the legendary research lab that gave rise to the Digital Age. In the 1970s and ‘80s, Xerox Corporation brought together a brain-trust of engineering geniuses dubbed PARC (Palo Alto Research Center). This brilliant group created several monumental innovations that triggered a technological revolution, including the first personal computer, the laser printer, and the graphical interface (one of the main precursors of the Internet). And when these breakthroughs were rejected by the corporation, these determined inventors turned their ideas into empires that changed the world. Based on extensive interviews with the scientists, engineers, administrators, and executives who lived the story, Dealers of Lightning details PARC’s rise from humble beginnings to a hothouse for ideas. It also shows why Xerox was never able to grasp the cutting-edge innovations PARC delivered. Michael A. Hiltzik offers an unprecedented look at the ideas, the inventions, and the individuals that propelled Xerox PARC to the frontier of techno-history—and the corporate machinations that almost prevented it from achieving greatness.
