Who they are

Douglas Engelbart (1925–2013) was an American engineer who in 1968, at a public technology demonstration in San Francisco thereafter called by the history of computing the "Mother of All Demos," first systematically showed the public a series of then near-science-fiction human-computer interaction ideas — including the computer mouse he had invented, the graphical window interface, hypertext links, real-time collaborative document editing, and even remote collaboration by video conference, many core interaction concepts that would only gradually become standard on personal computers decades later — and all of this was a public demonstration completed in an age when computers still mainly relied on punched cards for batch processing. Engelbart’s core idea in designing the computer mouse sprang from his long thought on the grand theme of "how to let the computer better augment and extend human intellect and collaboration ability," and he himself always held the mouse a relatively minor technical detail in this grand vision, the truly important thing being to raise systematically, by technical means, humanity’s collective ability to solve complex problems collaboratively. Yet this strikingly forward-looking demonstration did not immediately provoke wide industrial follow-up, and Engelbart’s later research long failed to gain resources matching the foresight of his ideas, until latecomers such as Xerox PARC and Apple in turn productized the graphical interface and mouse technology and brought it to market, and the ideas he showed gradually became the standard way ordinary people use computers daily.

Key stories

The "Mother of All Demos": A Demonstration Nearly Thirty Years Ahead of Its Time

In December 1968, at a computer academic conference in San Francisco, Engelbart demonstrated live to the audience a series of functions — mouse control, multi-window interface, hypertext jump links, real-time collaborative document editing, and even remote video collaboration — ideas that only gradually became standard on personal computers nearly twenty to thirty years later, and this public demonstration thereafter hailed as the "Mother of All Demos" is the acknowledged most forward-looking and far-reaching technical demonstration in the history of computer interaction design.

The Mouse Was Only Invented "in Passing"

Engelbart himself always stressed that the core theme he truly cared about all his life was how to "augment" human intellect and collective collaboration ability systematically by technical means, not to invent some concrete hardware tool, and the computer mouse was in fact only a solution designed in passing in exploring this grand theme, to solve the concrete interaction detail of "how to locate the cursor on screen more naturally," yet unexpectedly became his most widely known invention and the one that most profoundly changed how ordinary people use computers daily.
