Jacob "Jack" Goldman, the founder of Xerox PARC, died Tuesday at 90. In the New York Times's obit, John Markoff describes how Goldman's vision convinced a copier company to invest in the future, even if it had no idea what to do with the returns: "PARC researchers designed a remarkable array of computer technologies, including the Alto personal computer, the Ethernet office network, laser printing and the graphical user interface. ... Years later, Dr. Goldman explained Xerox’s failure ... as part of a large corporation’s unwillingness to take risks."
