Douglas C. Engelbart Inventor Of The Mouse

First Mouse: [top view] Doug Engelbart invented the computer mouse in 1963-64 as part of an experiment to find better ways to point and click on a display screen. This was fashioned downstairs in the shop at SRI, with the casing carved out of wood, with just 1 button - that's all there was room for. Subsequent model of the mouse very soon had three buttons; Engelbart would've have gone for more buttons but there was only room for three of the then-available micro-switches.
