Adobe co-founder Charles “Chuck” Geschke passed away Friday at the age of 81, Adobe has confirmed. During his career, Geschke oversaw Adobe’s operations as it released game-changing innovations include Photoshop, along with ubiquitous file formats such as PDF.
Adobe’s history has long been entwined with Apple — including a $2.5 million investment from Apple in 1985 that led to the creation of a PostScript controller for the Apple LaserWriter.
