New Scienist 19 June 1993, 32-35. About Alan Kay, one of the inventors of the 
personal computer. In 1968 he developed a model for a portable computer, 
called Dynabook, and joined Xerox, where he was one of the founders of PARC 
(the Palo Alto Research Centers). There he created the prototype of a
 personal computer with an interactive graphical user interface, a forerunner 
of the Macintosh. In 1974, such innovations were too revolutionary even for 
Xerox. Kay stayed with Xerox until 1981, before moving to Atari and then, in 
1984, to Apple.
