At a Computer Conference in 1968, Engelbart demonstrated a personal computer with a one-handed keyboard, word processing, split windows, shared documents, e-mail filtering, desktop conferencing and a mouse.
In the immediate post-WW2 period, Douglas Englebart was stationed in the Phillipines when he borrowed a book from the Red Cross library which changed his life. The book was Vannevar Bush's "As We May Think" and it profoundly influenced not just the remainder of Englebart's life, but arguably the hundreds of millions of people in the world who have or will ever use a computer.
Not only did Englebart embrace Bush's concept of a machine which would assist human cognition and endeavour, but he actively involved himself in the field of computer-human interface and augmentation. Two decades later, he developed the idea that would form the basis of today's computer interfaces - the mouse.Engelbart founded the Augmentation Research Centre (ARC) at Stanford with the catch-cry, "Augmentation not automation".
His vision was important, because many people saw the computer as being a machine which would replace the human rather than greatly improve their capabilities.Though Engelbart may be best remembered for his invention of the mouse, which was subsequently licensed to the famous Palo Alto Research Centre and then to Apple computers, much of his work is characterised by its relevance to the computer and the greater good.
He was instrumental in developing the graphical user interface for the computer, and of championing "groupware" for collaborative environments. See the original presentation
On December 9, 1968, Douglas C. Engelbart and the group of 17 researchers working with him in the Augmentation Research Center at Stanford Research Institute in Menlo Park, California, presented a 90-minute live public demonstration of the online system, NLS, which they had been working on since 1962.
