Adobe CEO who led desktop publishing revolution

John Warnock, who played a seminal role in the history of computing as cofounder and chief executive of Adobe Inc., helping create the Portable Document Format (PDF) and software that turned computers into digital printing presses, radically reshaping office life and publishing, died Aug. 19. He was 82.

Adobe announced his death but did not give further details. The company provided his biography in a PDF.

Mr. Warnock and Charles Geschke founded Adobe in 1982, naming it after a creek near their homes in Los Altos, Calif. PostScript, the company’s first piece of software, let computer users print documents just as they appeared on-screen, with graphics and multiple fonts — a task that previously required a trip to a local printing press.

Apple was the first company to adopt the software, integrating it into its new LaserWriter printer. Other printer manufacturers soon followed.

“When that first page came out of the LaserWriter, I was blown away,” Apple co-founder Steve Jobs told the tech journalist Pamela Pfiffner for her 2003 book “Inside the Publishing Revolution: The Adobe Story.” “No one had seen anything like this before. I held this page up in my hand and said, ‘Who will not want that?’ I knew then, as did John, that this was going to have a profound impact.”

PostScript meant anyone essentially could run their own printing press, democratizing publishing and making Mr. Warnock and Geschke technological descendants of Johannes Gutenberg, the German inventor of the printing press. Adobe received letters and notes of thanks not long after the LaserWriter launched in 1985.

“The first note we got was from these ladies who told us how excited they were to be able to publish their magazine,” Dan Putnam, one of Adobe’s first employees, said in Ms. Pfiffner’s book. “It was a lesbian newsletter, kind of pornographic in nature. The second newsletter that arrived was from a fundamentalist Christian sect. It wasn’t exactly what we had in mind, but we gave them the voice to present their point of view.”

Jobs wanted to buy Adobe outright, but “we weren’t quite ready to be subservient to Steve,” Mr. Warnock told The Washington Post in 2021 after Geschke’s death.

Other dynamic duos in Silicon Valley were better known — Jobs and Steve Wozniak at Apple, William Hewlett and David Packard at Hewlett-Packard — but Mr. Warnock and his cofounder led Adobe through a remarkable period of growth that made it one of the world’s largest software producers.

Most of the company’s initial growth derived from Acrobat, introduced in 1993. The software ushered in the paperless office by letting computer users share documents as PDFs, preserving fonts and graphics regardless of the underlying software that created them.

Acrobat did not catch on as quickly as PostScript.

In a meeting with IBM executives, “I explained how it worked, what its advantages were and how, from any application, you could send a completely portable document across platforms,” Mr. Warnock said in an interview with a business journal published by the Wharton School of the University of Pennsylvania. “They just sat there in the meeting with blank stares. They had no idea what I was talking about.”

He recalled thinking,

“How stupid can the world be?”

Eventually, Acrobat’s merits became apparent.

“The Centers for Disease Control was one of our earliest and most fanatical adopters,” Mr. Warnock told the Wharton journal. “They said, ‘Do you know how many people’s lives we can save by sending these documents out to all of the field offices?’ ... The IRS loved it.”

Adobe’s other notable publishing products inc PageMaker and Illustrator. believed Mr. Warnock, technology like could Jobs, serve a higher purpose. “We always felt that Apple should stand at the intersection of art and technology, and John felt the same way about Adobe,” Jobs said. “John had a developed aesthetic sense, We meshed together well.”
