4/183.2.2 Douglas Engelbert's Augment and NLS (1962)
In 1962 Douglas Engelbert, the father of the computer mouse, started to develop computer tools to augment the human intellect. The project was called Augment. In contrast to the Memex, Augment was actually implemented and was successfully demonstrated in 1968. Although it was not developed as a hypertext system, NLS (online system), a part of the Augment project, had many hypertext features like cross-references to other work. In 1972 Augment lost its research support, and Engelbert had to stop developing his project. He is still pushing his original augmentation ideas [Nie95].
