who invented the computer mouse

Douglas Engelbart, an American engineer at Stanford Research Institute (SRI), is widely credited as the inventor of the modern computer mouse in the early 1960s.

Quick Scoop

• The computer mouse was invented by Douglas Engelbart at SRI (now SRI International) in the early 1960s.

• His device was first described in a 1965 report as an “X‑Y position indicator for a display system,” not yet called a mouse.

• Engelbart’s mouse was first publicly demonstrated on December 9, 1968, during the famous “Mother of All Demos” in San Francisco.

• The original mouse was a small wooden box with two internal wheels at right angles, plus a cord that made it look like a tail.

• Engelbart’s employer SRI held the patent (granted in 1970) and he received no royalties, even though the mouse later became standard on personal computers.

How the Mouse Came About

In the early 1960s, Engelbart was leading the Augmentation Research Center at SRI, working on ways to improve how humans interact with computers. At the time, people mainly used punch cards, typed commands, or clumsy pointing tools like light pens and joysticks, which were slow and awkward.

Engelbart imagined interactive computing where a person could directly manipulate on‑screen text and graphics in real time. To support that vision, his team experimented with different pointing devices until they built a small wooden box with internal moving mechanisms that tracked motion on a flat surface.

The First Mouse and the 1968 Demo

The first mouse prototypes appeared around 1963 at SRI, with a blocky wooden body and a cable trailing behind—hence the nickname “mouse.” Inside were orthogonal wheels (and later ball‑based mechanisms) that translated hand motion into cursor movement on a screen.

On December 9, 1968, Engelbart and his team gave a legendary 90‑minute demonstration of their oN‑Line System (NLS) at a computer conference in San Francisco. In that single session they showed the mouse, hypertext links, windowed interfaces, real‑time collaborative editing, and video conferencing—features that foreshadowed modern personal computing.

Was Anyone Else Involved?

Although Engelbart is credited as the mouse’s inventor, it was a team effort in practice. Engineer Bill English at SRI built the first working wooden prototype and co‑authored the early technical report that mentioned the device. Later, companies like Xerox PARC, Apple, and Microsoft refined the mouse and helped turn it into a mainstream tool for personal computers in the 1970s and 1980s.

Some earlier pointing devices, such as trackballs developed for military and specialized systems, predate Engelbart’s mouse, but they were not the same desktop “mouse” concept that ended up on ordinary office and home computers. This is why mainstream histories and major references consistently name Engelbart as the inventor of the computer mouse.

TL;DR: Douglas Engelbart invented the computer mouse at SRI in the early 1960s and unveiled it publicly in the 1968 “Mother of All Demos,” laying the groundwork for modern graphical computing.
