Evans was born in
Salt Lake City. He attended the University of Utah and studied electrical engineering; he earned his Bachelor of Science in physics in 1949 and his Doctorate in Physics in 1953. Evans first worked at the
Bendix aviation electronics company, where he acted as project manager in 1955 to develop what some describe as an early
personal computer that ran on an interpretive operating system. The
Bendix G-15 was a bulky unit about the size of a two-door refrigerator. He stayed with the company just long enough to manage the G-20 project. Evans became a faculty member of the
University of California, Berkeley. His first important work with graphics dates from that period, when he did several experiments on an IDIOM display hooked up to a
Digital Equipment Corporation PDP-5. In 1963, he was co-
Principal Investigator (with
Harry Huskey) for
project Genie to produce an early multi-user
timesharing system. Students from this period include
Butler Lampson and
L. Peter Deutsch. The system, which included key developments in the field of
virtual memory, was sponsored by the US Defense Department's
Advanced Research Projects Agency. Evans was awarded the
Silver Beaver for his role in scouting. Evans married Joy Frewin. They had ten children, only seven of which lived to adulthood. One of these is
David F. Evans, who became a
general authority in the LDS Church. From 1984 to 1990, Joy Evans was a counselor in the general presidency of the
Relief Society to
Barbara W. Winder. At the time of his death on October 12, 1998, Evans had 39 living grandchildren and great-grandchildren. In 1996,
Brigham Young University established the David C. Evans Chair of Computer Engineering and Graphics. Evans was at the ceremony where the founding of a chair in his honor was announced, but due to his suffering from
Alzheimer's disease, did not make any remarks at the ceremony. ==References==
