Douglas C. Engelbart (born January 30, 1925 in
Oregon) is an American inventor of
Swedish and
Norwegian descent. As a
World War II naval radio
technician based in the
Philippines, Engelbart was inspired by
Vannevar Bush's article "
As We May Think". Engelbart received a
Bachelor's degree in electrical engineering from
Oregon State University in 1948, a B.Eng. from
UC Berkeley in 1952, and a
Ph.D. in
EECS from UC Berkeley in 1955. At
Stanford Research Institute , Engelbart was the primary force behind the design and development of the
On-Line System, or NLS. He and his team at the
Augmentation Research Center developed computer-interface elements such as bit-mapped screens, groupware,
hypertext and precursors to the
graphical user interface. In 1967, Engelbart applied for and later received a
patent for the wooden shell with two metal wheels (
computer mouse). Engelbart later revealed that it was nicknamed the "mouse" because the tail came out the end. He would also work on the
ARPANET, the precursor of the
Internet. In later years he moved to the private firm Tymshare after SRI was transferred to the company.
McDonnell Douglas took over the copany in 1982, and in 1986 he left the company. As of 2007, he is the director of his own company, the Bootstrap Institute, which founded in 1988 and located in
Fremont, California.
