John Warnock

John Edward Warnock earned a PhD in electrical engineering from the University of Utah in 1969, where he studied under computer graphics pioneer Ivan Sutherland. He joined Xerox PARC in 1978 and led the development of the Interpress page description language. Warnock's academic background in mathematics and computer science gave him the theoretical foundation to create PostScript, which required solving complex problems in font rendering, curve mathematics, and device-independent graphics.

John Warnock co-founded Adobe Systems in December 1982 after leaving Xerox PARC, frustrated that Xerox would not commercialize the Interpress technology he had developed. As Adobe's first CEO, Warnock led the creation of PostScript (1984), which revolutionized desktop publishing by enabling any computer to produce professional-quality printed output. He oversaw Adobe's IPO in 1986 and guided the company's expansion into end-user applications with Illustrator (1987) and the acquisition of Photoshop distribution rights (1989). In 1993, Warnock championed the creation of PDF through his 'Camelot Project' vision paper, establishing what would become the world's universal document format. He served as CEO until 2000 and remained co-chairman of the board until 2017. Warnock received the National Medal of Technology and Innovation in 2009 and the ACM A.M. Turing Award (shared with Geschke) in 2023 for their contributions to computer science through PostScript and PDF.
