John Warnock, who invented the PDF and co-founded Adobe Systems, has died at age 82

Warnock worked for Xerox before he and colleague Charles Geschke created a company around a rejected idea in 1982. Nearly a decade later, Warnock outlined an early version of the Portable Document Format, or PDF, transforming the way documents are exchanged.Originally from the Salt Lake City suburb of Holladay, Warnock described himself as an average student who later flourished in mathematics.

“I had an amazing teacher in high school who, essentially, completely turned me around,” Warnock said. “He was really good at getting you to love mathematics, and that’s when I got into it.” After a summer spent working at a tire shop, he decided the low-paying field of academia wasn’t for him and applied to work at IBM, starting his training in computer science. He earned a doctorate at the University of Utah, where he joined a group of cutting-edge researchers working on a Department of Defense-funded precursor to the internet in the 1960s. Even then, Warnock was working on rendering images on computers.

With that, Adobe took off, and PDF eventually replaced many paper copies in legal, business and personal communication.
