John Warnock, who helped invent the PDF and co-founded Adobe Systems, has died.
The Silicon Valley entrepreneur and computer scientist died Saturday surrounded by family, Adobe said in a statement. The company didn't give a cause of death or say where Warnock died.
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.
