Saint Ignatius High School and went on to earn a
BA in
classics and an MS in
mathematics from Xavier University, as well as a
PhD in
computer science from
Carnegie Mellon University.Prior to co-founding Adobe, Geschke and Warnock worked at
Xerox's
Palo Alto Research Center (PARC). Geschke had started there in the early
1970s. Geschke formed and headed PARC's Imaging Sciences Laboratory in
1978 or

Interpress graphics language for controlling printing, the two left Xerox to start Adobe. At their new company, they developed an equivalent technology,
PostScript, from scratch, and brought it to market.
