Doug Engelbart Biography The first mouse, built by Doug Engelbart in the mid-1960s. Two wheels kept track of the device's movements. Patents In 1968, Engelbart donned a headset microphone and demonstrated his oNLine System (NLS) to a crowd of computer scientists. The NLS also included a new kind of keyboard—users typed letters by striking a combination of its five keys. Videos The first mouse was a simple hollow-out wooden block, with a single push button on top.

oNLine System Demo
On December 9, 1968, Doug Engelbart and the researchers working with him at the Augmentation Research Center staged a demonstration of the computer they had built, the oNLine System, or NLS. Below are several excerpts from the video of that demo, covering the highlights of the NLS. The original 90-minute video is part of the Engelbart Collection in the Special Collections of Stanford University; for more excerpts, see Links & Resources.

The NLS's input devices are displayed, including the first computer mouse. "I don't know why we call it a mouse," Engelbart explains. "It started that way and we never changed it."
