Charles “Chuck” Geschke, a co-founder of Adobe who helped develop
the PDF, has died at age 81, the company said in a
Geschke earned a doctorate from Carnegie Mellon University in
Pittsburgh, and then took a job at Xerox Palo Alto Research Center
where he met Warnock. The pair left Xerox in 1982 and founded
Adobe. Their first product was Adobe PostScript, the programming
language that helped boost the desktop publishing industry.
Geschke was chief operating officer of Adobe from December 1986 to
July 1994 and president from April 1989 until his retirement in
April 2000. He served as chairman of the board with Warnock from
September 1997 to January 2017 and was a member of the board until
April 2020, when he became emeritus board member.
“I could never have imagined having a better, more likable, or
more capable business partner,” Warnock said in a statement. “Not
having Chuck in our lives will leave a huge hole and those who
knew him will all agree.”
Impossible to overstate how important PostScript was (and remains). What made PostScript so good, so useful, so lasting, is that it’s a full-fledged programming language.
