scumm writes "This year's Turing Prize has been awarded to Charles Thacker, whom they describe as (among other things) the 'creator of the first modern personal computer.' From the ACM's announcement: 'ACM, the Association for Computing Machinery today named Charles P. Thacker the winner of the 2009 ACM A.M. Turing Award for his pioneering design and realization of the Alto, the first modern personal computer, and the prototype for networked personal computers. Thacker's design, which he built while at Xerox PARC (Palo Alto Research Center), reflected a new vision of a self-sufficient, networked computer on every desk, equipped with innovations that are standard in today's models. Thacker was also cited for his contributions to the Ethernet local area network, which enables multiple computers to communicate and share resources, as well as the first multiprocessor workstation, and the prototype for today's most used tablet PC, with its capabilities for direct user interaction.' For further reading, the Wall Street Journal has an article providing more background about Mr. Thacker and the Turing Prize. In the spirit of full disclosure, the submitter feels compelled to point out that this Mr. Thacker is his uncle, and that he thinks this is really cool."
