Dr. Warnock passed away on Saturday surrounded by his family. With the death of [2]John Warnock, we've lost another titan of the tech world. He co-founded Adobe Systems in 1982 with [3]Chuck Geschke, who died several years ago (see '[4]Adobe Co-Founder Charles Geschke Dead at 81,' 19 April 2021). In the late 1970s, they developed the graphics language InterPress at Xerox PARC, but when Xerox failed to commercialize it, they left to start Adobe. There they developed the PostScript page description language that underpinned Apple's groundbreaking LaserWriter, and the combination sparked the desktop publishing revolution. Warnock is also credited with inventing Adobe Illustrator to create graphics in PostScript without programming. The impact of Warnock's and Geschke's work is incalculable'[5]this video about the history of Illustrator gives a sense of just how difficult graphic design was before tools like PostScript and Illustrator came onto the scene.
