Charles Geschke, co-founder of Adobe, a software company that helped develop the Portable Document Format (PDF), died at the age of 81.

Geschke founded Adobe in 1982, providing the world with ubiquitous PDF software, among other audiovisual innovations.

He became a hot topic ten years later when he was kidnapped by a gun, demanded a ransom, and then released unharmed after four days of trials.

Geschke died in California on Friday.

Adobe CEO Shantanu Narayen said Geschke, widely known as Chuck, “has triggered a desktop publishing revolution.”

“This is a huge loss to the entire Adobe community and the tech industry, and he has been a guide and hero for decades,” he emailed an employee of the company.

“As co-founders of Adobe, Chuck and John Warnock have developed breakthrough software that has revolutionized the way people create and communicate,” he said.

According to Narayen, Geschke and Warnock were responsible for inventing innovative software such as PDF, Acrobat, Illustrator, Premiere Pro, and Photoshop.

In 1992, Geschke was kidnapped in an incident that became a national headline.

He was struck by a gun in his office and taken to Hollister, California for four days.

Geschke was released after a suspect found at a ransom of $ 650,000 (£ 470,000) took police to the place where he was detained, according to the Associated Press.

“He was a really humble and humble man. As his wife, I can say that,” said Nan Geschke. I told Mercury News. “Of course, he was very proud of his success, but he was very cautious about how much it had to do with it.”
