At a Churchill Club event in San Jose, Calif., former PARC engineer Larry Tesler talks about Steve Jobs' trips to Xerox's PARC, including the one where Jobs eyed the company's graphical user interface prototype, which ended up making it into the Mac OS. Tesler decided to leave Xerox soon after and started working at Apple.
