Charles “Chuck” Thacker (B.A.’67 Physics), a pioneer in the development of the personal computer and computer networking, died in June at age 74. In 1968, he joined the Department of Electrical Engineering’s Project Genie team, which built an early computer time-sharing system; he and others eventually left to form the Berkeley Computer Corporation, where Thacker led the design of a new computer processor and memory system. He later was project leader of the team at Xerox PARC (Palo Alto Research Center) that built the Alto, the first modern personal computer. Alto had a revolutionary graphical user interface, which was used by Apple and Microsoft in making the Macintosh and Windows operating systems. He was also co-inventor of the Ethernet local-area network, and was a key contributor to the first laser printer. In 1983, he helped start Digital Equipment Corporation Systems Research Center, where he led the hardware development of Firefly, the first multiprocessor workstation. He then joined Microsoft’s Tablet PC group in the late 1990s, where he oversaw the design of the first prototypes. In 2009, Thacker received the Turing Award, considered to be the “Nobel Prize in Computing,” for his many contributions to modern computing. (Photo used with permission from Microsoft)
