Computer, internet visionary dies
Lab chief foresaw personal computers
In 1968, Robert W. Taylor made a prediction that would guide the course of computer science for decades to come.
“In a few years,” he wrote, “men will be able to communicate more effectively through a machine than face to face.”
Taylor, who died Thursday at the age of 85, became the single most important force in making his own vision come true. As a civilian official at the Pentagon’s Advanced Research Projects Agency in the 1960s, he approved the funding to launch the government computer network that would ultimately evolve into the internet.
And as one of the original laboratory chiefs at the fabled Xerox Palo Alto Research Center, or PARC, he supervised the work that produced the first personal computer; the graphical user interface that was the model for Microsoft Windows and the Apple Macintosh display; the laser printer; the Ethernet local network; and many more advances.
Taylor, who suffered from Parkinson’s disease and other ailments, died at his home in the San Francisco Bay Area town of Woodside, according to his son Kurt.
Taylor may have been little known to the general public, but he was a revered figure among computer scientists and designers — many of whom received their earliest funding or developed their pioneering concepts with his help. Taylor’s lab at PARC spawned companies and concepts that would help to place California’s Silicon Valley at the center of the digital business world.
“From the early 1960s, Bob always had a very clear vision of the potential of the computer at a time when very few other people had really grasped it,” recalled Butler Lampson, one of the designers of the Alto, PARC’s groundbreaking personal computer.Born in 1932 in Dallas, Taylor never lost the West Texas twang he acquired during his Depression-era upbringing as the adopted son of a Methodist minister and his wife. He earned a master’s degree in psychology at the University of Texas, and eventually joined the Pentagon as a research official.
His superior, psychologist J.C.R. Licklider, was devoted to “finding ways to make computers easier to use” — and especially making them interactive, Taylor recollected years later. At that time, computers were roomsize monstrosities that operated on the “batch” principle. A user would write an entire program on punch cards or spools of punched tape, feed it into the machine, wait for it to be processed, and then correct or rewrite it and feed it all back in. “It was an unbelievable rigmarole,” Taylor recalled. Moreover, every brand of computer ran on a proprietary language that made them all mutually unintelligible.
At the Advanced Research Projects Agency, Taylor witnessed the drawbacks of this arrangement firsthand. He had three terminals in his office, each linked to a computer project he was funding at three separate academic institutions. They could communicate with him, but not with one another, which prevented rather than fostered collaboration among ARPA’s researchers.
“You don’t have to be halfsmart to see that this thing ought to be designed such that you just have one terminal and you can go wherever you want to go,” Taylor explained many years later. In 1966, he proposed such a system to ARPA’s chief, Charles Herzfeld, who saw the point immediately and approved the “million dollars or so” Taylor told him he needed to get the project off the ground.
“That,” Taylor remembered years later, “was literally a 20-minute conversation.” From that conversation was born the ARPAnet, which over the ensuing decades evolved into the internet.
By 1969, Taylor had become disaffected with ARPA, which was losing its independence as a civilian research unit and becoming more focused on military projects related to the Vietnam War. He left the agency, and soon after received an invitation from Xerox, which was launching a research outpost on the West Coast. Xerox hoped to diversify beyond its enormous franchise in large-scale office copiers and develop technologies for what it called the “office of the future.” The new operation was founded in 1970 as its Palo Alto Research Center.
