Charles Geschke
Charles Matthew "Chuck" Geschke (September 11, 1939 – April 16, 2021) was an American businessman and computer scientist best known for founding the graphics and publishing software company Adobe Inc. with John Warnock in 1982, with whom he also co-created the PDF document format.
Charles Matthew Geschke was born in Cleveland, Ohio, on September 11, 1939. He attended Saint Ignatius High School.
Geschke earned an BA in classics in 1962 and an MS in mathematics in 1963, both from Xavier University. He taught mathematics at John Carroll University from 1963 to 1968. In 1972, he completed his PhD studies in computer science at Carnegie Mellon University under the advice of William Wulf. He was a co-author of Wulf's 1975 book The Design of an Optimizing Compiler.
Geschke started working at Xerox's Palo Alto Research Center (PARC) in October 1972. His first project was to build a mainframe computer. Afterward, he worked on programming languages and developed tools that were used to build the Xerox Star workstation.
In 1978, Geschke started the Imaging Sciences Laboratory at PARC, and conducted research in the areas of graphics, optics, and image processing. He hired John Warnock, and together they developed Interpress, a page description language (PDL) that could describe forms as complex as typefaces. Unable to convince Xerox management of the commercial value of Interpress, the two left Xerox to start their own company.
Geschke’s interviews are often featured in documentary films produced by the Silicon Valley Historical Association, including the PBS Silicon Valley, a One Hundred Year Renaissance, narrated by Walter Cronkite (1998)
Geschke and Warnock founded Adobe in Warnock's garage in 1982, naming the company after the Adobe Creek that ran behind Warnock's home. Interpress eventually evolved into PostScript. Its use on Apple computers resulted in one of the first desktop publishing (DTP) systems which allowed users to compose documents on a personal computer and see them on screen exactly as they would appear in print, a process known as WYSIWYG, an acronym for What You See Is What You Get. Previously, graphic designers had been forced to view their work in text-only format while they worked, until they printed, or hit "print preview". Because of the high quality and speed at which printing and composing could be done in WYSIWYG, the innovation "spawned an entire industry" in modern printing and publishing.
From December 1986 until July 1994, Geschke was Adobe's Chief Operating Officer, and from April 1989 until April 2000 he was the company's president. Geschke retired as president of Adobe in 2000, shortly before his partner Warnock left as CEO. Geschke had also been Co-Chairman of the Board of Adobe from September 1997 to 2017.
