Educated in physics at the University of California at Berkeley, Thacker joined the university's "Project Genie" in 1968, an effort that resulted in one of the most successful early timesharing systems. The Genie team later formed the Berkeley Computer Corporation. BCC supplied the core group of technologists for the newly-formed Computer Science Laboratory (CSL) at the Xerox Palo Alto Research Center (PARC), which Thacker joined in 1970. During his thirteen years at PARC, Thacker led the hardware development of many of the innovative systems developed at CSL. At PARC Thacker was co-inventor (with Metcalfe, Boggs, and Lampson) of the Ethernet local area network. He contributed to the world's first laser printer, and to the "Dorado" high-performance personal workstation. He also designed and implemented the SIL CAD system, which was used by most of PARC's hardware designers throughout the 1970s. In 1983 Chuck was a founder of DEC's Systems Research Center (SRC) in Palo Alto, California. There he led hardware development of the "Firefly", the first multiprocessor workstation, and the Alpha Demonstration Unit, the first Alpha-architecture multiprocessor. Thacker also worked in computer networking, leading development of AN1 and AN2 networking systems. In 1997, he joined Microsoft to help establish the company's Cambridge, U.K. Research Laboratory. After returning to the U.S. in 1999, he joined the newly-formed Tablet PC group and managed the design of the first prototypes of this new device. He is currently establishing a group at Microsoft Research in Silicon Valley to explore new areas in computer architecture. Thacker holds a B.S. degree in Physics from UC-Berkeley (1967) and an Honorary Doctorate from the Swiss Federal Institute of Technology (ETH-Zurich).
