John Warnock

John Warnock founded Adobe alongside Charles Geschke in 1982, having both left Xerox.

At their new company, they developed PostScript from scratch, having failed to convince Xerox that their previous similar development, InterPress, was worth publishing. PostScript was first brought to market for Apple's LaserWriter in 1985.

In the spring of 1991, Warnock outlined a system called "Camelot". This eventually evolved into the Portable Document Format - (PDF) file-format we know today.

Warnock has received honorary degrees from the University of Utah, the American Film Institute, and The University of Nottingham.

Warnock is now known for having pioneered the development of graphics, publishing, Web and electronic document technologies that have revolutionized the field of publishing and visual communications.

There is an Adobe font, Warnock, named after him.
