Charles P. Thacker, designer of the Xerox Alto, passes away

Charles P. Thacker ("Chuck" to those who knew him), who helped pioneer many aspects of the personal computer, and who was awarded the 2009 ACM A.M. Turing Award in recognition of his pioneering design and realization of the first modern personal computer, and for his contributions to Ethernet and the tablet computer, died Monday, June 12, at the age of 74, after a brief illness.[...]Thacker spent the 1970s and 1980s at PARC. During this period, he served as leader of the project that developed the Xerox Alto personal computer system, the first computer designed from the ground up to support an operating system based on a graphical user interface. The hardware of the Alto, introduced in 1973, was designed mostly by Thacker, with Lampson developing its software.It's hard to put into words how much this man - and his peers and team at Xerox - contributed to the world of computing. What an incredible genius to lose.Thank you for your immeasurable contributions, good sir.
