  • M.S. in Mathematics, Xavier University, 1963
  • Ph.D. in Computer Science, Carnegie-Mellon University, 1972

From 1963-68, Dr. Geschke taught Mathematics at John Carroll University.

In the 1970s, Geschke worked as a research scientist at Xerox's Palo Alto Research Center (PARC). In 1978, he and a colleague, John Warnock, invented a Page Description Language (PDL)—a means of describing complex forms like typefaces electronically—called Interpress. When Xerox decided not to commercialize this invention, Geschke and Warnock left PARC and co-founded Adobe Systems (adapted from link below).

Geschke retired as Adobe's President in 2000, but still serves as Chairman of the Board.
