John Warnock
Co-founder 1982Background
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.
Role at Adobe Inc.
Adobe was founded in December 1982 by John Warnock and Charles Geschke, two brilliant computer scientists who had previously worked together at Xerox PARC (Palo Alto Research Center), the legendary research lab that birthed the modern graphical user interface. While at Xerox, Warnock and Geschke were working on a page description language—code that could tell a computer printer exactly how to render complex text and graphics on a page. When Xerox management refused to commercialize their specific approach, the two men left to start their own company, naming it 'Adobe' after the Adobe Creek that ran behind Warnock's home in Los Altos. Their foundational product was PostScript. Prior to PostScript, printing complex documents from a computer was a nightmare; every application had to have specific drivers for every single brand of printer, and the results were often jagged and pixelated. PostScript was revolutionary because it was device-independent: it treated text and graphics as mathematical vectors rather than raw pixels. This meant a document would look exactly the same on a computer screen as it did coming out of a high-end commercial printer. In 1985, Apple's Steve Jobs (who had tried unsuccessfully to buy Adobe outright) licensed PostScript to use in the Apple LaserWriter printer. Paired with the Macintosh computer and Aldus PageMaker software, this trio of technologies single-handedly birthed the 'Desktop Publishing' revolution, destroying the traditional, expensive typesetting industry overnight. Adobe's early dominance in PostScript royalties provided the financial runway that allowed Warnock and Geschke to develop their own suite of software applications, most notably launching Adobe Illustrator in 1987 and acquiring a small image-editing program called Photoshop in 1989, thereby cementing their total dominance over the digital creative world.
