Adobe共同创始人Chuck Geschke和John Warnock：我们从未抛弃苹果

In the Spring of 1991, Warnock outlined a system called "Camelot"[4], that evolved into the Portable Document Format (PDF) file-format. The goal of Camelot was to "effectively capture documents from any application, send electronic versions of these documents anywhere, and view and print these documents on any machines". Warnock's document contemplated, "Imagine if the IPS (Interchange PostScript) viewer is also equipped with text searching capabilities. In this case the user could find all documents that contain a certain word or phrase, and then view that word or phrase in context within the document. Entire libraries could be archived in electronic form..."

One of Adobe's popular typefaces, Warnock, is named after him.

Adobe's PostScript technology made it easier to print text and images from a computer, revolutionizing media and publishing in the 1980s.

In 2003 Warnock and his wife donated 200,000 shares of Adobe Systems valued at over 5.7 Million dollars[5] as the main gift for a new engineering building. The John E. and Marva M. Warnock Engineering Building was completed in 2007 and houses the University of Utah College of Engineering.

Dr. Warnock holds seven patents. In addition to Adobe Systems, he serves or has served on the board of directors at ebrary, Knight-Ridder, MongoNet, Netscape Communications and Salon Media Group. Warnock is a past Chairman of the Tech Museum of Innovation in San Jose. He also serves on the Board of Trustees of the American Film Institute and the Sundance Institute.

Hobbies include Photography, Skiing, Web Development, Painting, Hiking, Curation of rare scientific books and historical Native American objects.[6]

A strong supporter of higher education, Warnock and his wife, Marva, have supported three presidential endowed chairs in computer science, mathematics and fine arts at the University of Utah and also an endowed chair in medical research at Stanford University.
