Charles Patrick “Chuck” Thacker (February 26, 1943 – June 12, 2017) was an American pioneer computer designer. He worked on the Xerox Alto, which is the first computer that used a mouse-driven Graphical User Interface.
He received his B.S. in physics from the University of California, Berkeley in 1967. He then joined the university’s “Project Genie” in 1968, which developed the pioneering Berkeley Timesharing System on the SDS 940. Butler Lampson, Thacker, and others then left to form the Berkeley Computer Corporation, where Thacker designed the processor and memory system. While BCC was not commercially successful, this group became the core technologists in the Computer Systems Laboratory at Xerox Palo Alto Research Center (PARC).
Thacker worked at the PARC in the 1970s and 1980s, where he served as project lead of the Xerox Alto personal computer system, was co-inventor of the Ethernet LAN, and contributed to many other projects, including the first laser printer.
In 1983, Thacker was a founder of the Systems Research Center (SRC) of Digital Equipment Corporation (DEC), and in 1997, he joined Microsoft Research to help establish Microsoft Research Cambridge in Cambridge, England.
After returning to the United States, Thacker designed the hardware for Microsoft’s Tablet PC, based on his experience with the “interim Dynabook” at PARC, and later the Lectrice, a pen-based hand-held computer at DEC SRC.
Thacker held an honorary doctorate from the Swiss Federal Institute of Technology and was a Technical Fellow at Microsoft.
Among numerous awards in his long and decorated career, Chuck received the Turing Award in 2009 and was honored with the ACM IEEE-CS Eckert-Mauchly Award posthumously in 2017. The Microsoft Research “Charles Thacker Breakthrough Award” was named in his honor.
