On 9 December 1968, Douglas Engelbart sat on a San Francisco stage and showed an audience the future. In ninety minutes he demonstrated the mouse, hypertext, windows, and live collaboration, most of modern personal computing, decades before any of it became ordinary.
The idea
The computer as a tool to augment human intellect, operated directly and interactively, rather than a number-cruncher fed by batch jobs. The interface itself, pointing, linking, and editing, is the contribution.
The demo
Engelbart presented a system called NLS, the oN-Line System, at a 1968 computer conference. The live demonstration introduced, for the first time and together, windows, hypertext, graphics, efficient navigation and command input, video conferencing, the computer mouse, word processing, dynamic file linking, revision control, and a real-time collaborative editor. It is remembered as “The Mother of All Demos” because so much arrived at once.
Augmenting intellect
Engelbart’s aim was to free computing from being merely about number crunching and to make it a tool for communication and information retrieval. He wanted to turn Vannevar Bush’s idea of the Memex into reality: a machine that, used interactively by one person, augments their intelligence.
The legacy
Nearly everything in the demo became commonplace. The direct-manipulation interface it pioneered was carried forward and refined at Xerox PARC, and from there it passed into every personal computer. Engelbart had shown the destination; others built the road.
