Douglas Engelbart

X-Y position indicator for a display system: the mouse—Douglas Engelbart envisioned a computer that would work in the modern office and made it a practical reality. In 1963, he began research at the Augmentation Research Center at Stanford Research Institute (SRI), and developed a pioneering hypermedia groupware system called NLS (for oN-Line System). NLS introduced two-dimensional computerized text editing using the mouse to position a pointer into the text. He first demonstrated NLS in 1968. This was the world debut of the mouse, hypermedia, and on-screen video teleconferencing. His project became the second host on ARPANET—the predecessor of the Internet. (1998)
