John Warnock, Co-Founder of Adobe Systems, Dies at 82

John Warnock, an American computer scientist and engineer who co-founded Adobe Systems, has passed away at the age of 82. Warnock was instrumental in developing fundamental technologies that transformed publishing and visual communications, including graphics, the web, electronic documents and print.

Early Life and Education

Born in 1940 in Salt Lake City, Utah, Warnock grew up in the suburb of Alder. He attended Olympus High School, where he received poor grades in mathematics but excelled in the humanities. After high school, Warnock went on to study mathematics, philosophy and electrical engineering at the University of Utah, earning his bachelor's degree in mathematics and philosophy in 1961.

Warnock continued his education at Utah, pursuing a Ph.D. in electrical engineering with a focus on computer science. He worked as a teaching assistant to support his education and received his doctorate in 1969.

Career at Xerox PARC

After graduating with his Ph.D., Warnock took a position at Xerox PARC (Palo Alto Research Center), a renowned research center that birthed many pioneering computer technologies. At PARC in the 1970s, Warnock worked on early raster graphics editors and laser printing.

Warnock worked alongside computer scientists like Alan Kay to develop groundbreaking object-oriented software. He was part of the team that developed InterPress, an early electronic and print publishing system that supported raster image processing.

Founding Adobe Systems'

In 1982, Warnock and fellow PARC alum Charles Geschke left Xerox to start their own company that would allow them to further develop and commercialize the InterPress technology. They founded Adobe in Warnock's garage in Los Altos, California.

The name “Adobe” was inspired by a creek that ran behind Warnock’s home. Adobe’s first product was PostScript, an innovative page description language for printing and publishing. PostScript powered Apple’s LaserWriter printer and formed the foundation for digital publishing.

Developing PDF Format

In the early 1990s, Warnock led the development of Portable Document Format (PDF) at Adobe. PDF was based on the PostScript language and allowed electronic documents to be shared across platforms and applications.

Released in 1993, PDF became widely adopted for everything from online forms to ebooks. Warnock’s format revolutionized document sharing and mobile access to information. Adobe Acrobat, the first PDF reader, cemented the popularity of the format.

Honors and Retirement

For his technical innovations, Warnock received many prestigious awards and honors over his long career. He was named a Fellow of the American Academy of Arts and Sciences, National Academy of Engineering, and American Philosophical Society.

Warnock served as Adobe’s CEO until 2000 and as chairman until 2002. He retired from Adobe in 2012 after 30 years helping to build the company into a powerhouse in digital media and creativity software.

Warnock died at age 82 on August 19, 2023. He leaves behind a tremendous legacy as a pioneer in publishing and document technology. From InterPress to PDF, Warnock’s innovations changed how people and businesses create, share, and consume digital information.
