Joseph C. Wilson

Xerox

Xerox pioneered the photocopier market starting with the Xerox 914 in 1959; Joseph C. Wilson signed an agreement in 1946 to develop Chester Carlson's invention commercially; before the 914, Xerox tested the market with the Flat-plate 1385 prototype, which proved nonviable due to slow speed; the 914—the first plain paper photocopier—was developed by Carlson and John H. Dessauer; researchers at Xerox and PARC invented key personal computing elements including the GUI, mouse, and desktop computing; Xerox opened PARC in 1970; and Gary Starkweather invented the laser printer in 1969 by modifying a Xerox 7000 copier.
