Taylor worked for NASA in
Washington, D.C. while the
Kennedy administration was backing research and development projects such as the
Apollo program for a crewed moon landing. In late 1962 Taylor met
J. C. R. Licklider, who was heading the new
Information Processing Techniques Office (IPTO) of the
Advanced Research Project Agency (ARPA) of the
United States Department of Defense. Like Taylor, Licklider had specialized in psychoacoustics during his graduate studies. In March 1960, he published “
Man–Computer Symbiosis”, an article that envisioned new ways to use computers. This work was an influential roadmap in the history of the internet and the personal computer, and greatly influenced Taylor. During this period, Taylor also became acquainted with
Douglas Engelbart at the
Stanford Research Institute in
Menlo Park, California. He directed NASA funding to Engelbart's studies of computer-display technology at SRI that led to the
computer mouse. The public demonstration of a mouse-based user interface was later called "
the Mother of All Demos." At the Fall 1968
Joint Computer Conference in
San Francisco, Engelbart,
Bill English,
Jeff Rulifson and the rest of the Human
Augmentation Research Center team at SRI showed on a big screen how he could manipulate a computer remotely located in Menlo Park, while sitting on a San Francisco stage, using his mouse.
ARPA In 1965, Taylor moved from NASA to IPTO, first as a deputy to
Ivan Sutherland (who returned to academia shortly thereafter) to fund large programs in advanced research in computing at major universities and corporate research centers throughout the United States. Among the computer projects that ARPA supported was
time-sharing, in which many users could work at terminals to share a single large computer. Users could work interactively instead of using
punched cards or
punched tape in a
batch processing style. Taylor's office in
the Pentagon had a terminal connected to time-sharing at
Massachusetts Institute of Technology, a terminal connected to the
Berkeley Timesharing System at the
University of California, Berkeley, and a third terminal to the
System Development Corporation in
Santa Monica, California. He noticed each system developed a community of users, but was isolated from the other communities. Taylor had convinced ARPA director
Charles M. Herzfeld to fund a network project earlier in February 1966, and Herzfeld transferred a million dollars from a ballistic missile defense program to Taylor's budget. Taylor hired
Larry Roberts from
MIT Lincoln Laboratory to be its first program manager. Roberts first resisted moving to Washington DC, until Herzfeld reminded the director of Lincoln Laboratory that ARPA dominated its funding. ARPA issued a
request for quotation (RFQ) to build the system, which was awarded to
Bolt, Beranek and Newman (BBN). ATT Bell Labs and
IBM Research were invited to join, but were not interested. At a pivotal meeting in 1967 most participants resisted testing the new network; they thought it would slow down their research. In 1968, Licklider and Taylor published "The Computer as a Communication Device". The article laid out the future of what the Internet would eventually become. It began with a prophetic statement: "In a few years, men will be able to communicate more effectively through a machine than face to face." The Vietnam project took him away from directing research, and "by 1969 I knew ARPANET would work. So I wanted to leave." Technologies developed at PARC under Taylor's aegis focused on reaching beyond ARPANET to develop what has become the Internet, and the systems that support today's personal computers. They included: • Powerful
personal computers (including the
Xerox Alto and later "D-machines") with windowed displays and graphical user interfaces that inspired the
Apple Lisa and
Macintosh. The Computer Science Laboratory built the Alto, which was conceived by
Butler Lampson and designed mostly by
Charles P. Thacker,
Edward M. McCreight,
Bob Sproull and
David Boggs. The Learning Research Group of PARC's Systems Science Laboratory (led by
Alan Kay) added the software-based "desktop" metaphor. •
Ethernet, which networks local computers within a building or campus; and
PARC Universal Packet (PUP) an early protocol for
internetworking that connected the Ethernet to the ARPANET, which was a forerunner to
TCP/IP and the
Internet. PUP was primarily designed by
Robert Metcalfe,
David Boggs,
Charles P. Thacker,
Butler Lampson and
John Shoch. • The electronics and software that led to the
laser printer (spearheaded by optical engineer
Gary Starkweather, who transferred from Xerox's
Webster, New York laboratory to work with CSL) and the
Interpress page description language that allowed
John Warnock and
Chuck Geschke to found
Adobe Systems. • "What-you-see-is-what-you-get" (
WYSIWYG) word-processing programs, as exemplified by
Bravo, which
Charles Simonyi took to
Microsoft to serve as the basis for
Microsoft Word. •
SuperPaint, a pioneering
graphics program and
framebuffer computer system developed by
Richard Shoup. The software was written in consultation with future
Pixar co-founder
Alvy Ray Smith, who could not secure an appointment at PARC and was retained as an independent contractor. Although Shoup received a special
Emmy Award (shared with Xerox) in 1983 and an
Academy Scientific Engineering Award (shared with Smith and
Thomas Porter) in 1998 for his achievement, program development continued to be marginalized by Taylor and PARC, ultimately precipitating Shoup's departure in 1979. Belying his lack of programming and engineering experience, Taylor was noted for his strident advocacy of Licklider-inspired distributed personal computing and his ability to maintain collegial and productive relationships between what was widely perceived as the foremost array of the epoch's leading computer scientists. This was exemplified by a weekly staff meeting at PARC (colloquially known as "Dealer" after
Edward O. Thorp's
Beat the Dealer) in which staff members would lead a discussion about myriad topics. They would sit in a circle of beanbag chairs and open debate was encouraged. According to Kay, the meeting "was part of the larger ARPA community to learn how to argue to illuminate rather than merely to win. ... The main purposes of Dealer -- as invented and implemented by Bob Taylor -- were to deal with how to make things work and make progress without having a formal manager structure. The presentations and argumentation were a small part of a deal session (they did quite bother visiting Xeroids). It was quite rare for anything like a personal attack to happen (because people for the most part came into PARC having been blessed by everyone there -- another Taylor rule -- and already knowing how 'to argue reasonably')." Throughout his tenure at PARC, Taylor frequently clashed with Elkind (who held budgetary responsibility for new projects but found his managerial authority undercut by Taylor's intimate relationships with the research staff) and Pake (who did not countenance Taylor's outsized influence in the laboratory and deprecatory attitude toward Xerox's physics research program, then directly overseen by Pake); as a result, he was not officially invited to the company's "Futures Day" demo (marking the public premiere of the Alto) in
Boca Raton, Florida in 1977. However, after one of Elkind's extended absences (stemming from his ongoing involvement in other corporate and government projects), Taylor became the manager of the laboratory in early 1978. In 1983, physicist and integrated circuit specialist William J. Spencer became director of PARC. Spencer and Taylor disagreed about budget allocations for CSL (exemplified by the ongoing institutional divide between computer science and physics) and CSL's frustration with Xerox's inability to recognize and use what they had developed. In a heated discussion led by Elkind and above, it was implied that Taylor without his PhD might be let go he said he would do them one better, "I quit", he said. After leaving the building, all of Taylor's scientists were brought into a large meeting room and were informed of his departure from PARC. A scientist stood up and said that they had better get him back and that if they didn't he would never set foot in this place again. Then, one by one, they all stood up and walked out. This sort of loyalty was unprecedented. By the end of the year, Taylor and most of the researchers at CSL who had left Xerox were rejoined again, this time in a Computer Corporation, not a copier company. A coterie of leading computer scientists (including Licklider,
Donald Knuth and
Dana Scott) expressed their displeasure with Xerox's decision not to retain Taylor in a letter-writing campaign to CEO
David Kearns.
DEC SRC Taylor was hired by
Ken Olsen of
Digital Equipment Corporation, and formed the
Systems Research Center in Palo Alto. Many of the former CSL researchers came to work at SRC. Among the projects at SRC were the
Modula-3 programming language; the snoopy cache, used in the
DEC Firefly multiprocessor workstation; the first multi-threaded Unix system; the first User Interface editor; the
AltaVista search engine and a networked Window System. ==Retirement and death==
