[PAR] [TLE] Douglas Engelbart [SEP] Douglas Carl Engelbart (January 30, 1925 – July 2, 2013) was an American engineer and inventor, and an early computer and Internet pioneer.  He is best known for his work on founding the field of human–computer interaction, particularly while at his Augmentation Research Center Lab in SRI International, which resulted in creation of the computer mouse, and the development of hypertext, networked computers, and precursors to graphical user interfaces.  These were demonstrated at The Mother of All Demos in 1968.  Engelbart's Law, the observation that the intrinsic rate of human performance is exponential, is named after him. [PAR] [TLE] NLS (computer system) [SEP] NLS, or the "oN-Line System", was a revolutionary computer collaboration system from the 1960s.  Designed by Douglas Engelbart and implemented by researchers at the Augmentation Research Center (ARC) at the Stanford Research Institute (SRI), the NLS system was the first to employ the practical use of hypertext links, the mouse, raster-scan video monitors, information organized by relevance, screen windowing, presentation programs, and other modern computing concepts.  It was funded by the Defense Advanced Research Projects Agency, NASA, and the U.S. Air Force.
