Douglas Engelbart, (born Jan. 30, 1925, Portland, Ore., U.S.—died July 2, 2013, Atherton, Calif.), U.S. computer scientist. He received a Ph.D. (1955) in electrical engineering from the University of California, Berkeley. In the 1960s he set up the Augmentation Research Center at the Stanford Research Institute. He invented hypertext, the multiwindow display, the mouse, and groupware. His demonstration of these capabilities in San Francisco in 1968 started the process of development that led to the Microsoft Windows operating system. Engelbart’s group at SRI was one of the original four members of the ARPANET, precursor of the Internet. After his retirement, he led the Bootstrap Institute, researching ways to support cooperative work by computers. In 1997 he received the Turing Award.
