The Inventor of the Computer Mouse: A Revolutionary Device

Last Updated: Feb 21, 2024 by

The computer mouse is a ubiquitous device that has become an essential tool for navigating the digital world. It allows us to easily click, scroll, and move our cursor on a computer screen, making it an integral part of our daily lives. But have you ever wondered who invented this revolutionary device? In this article, we will explore the history of the computer mouse and the inventor behind it.

The Early Days of the Computer Mouse

The first computer mouse was invented in 1964 by Douglas Engelbart, a computer scientist and inventor. At the time, Engelbart was working at the Stanford Research Institute (SRI) in California, where he was conducting research on human-computer interaction. He wanted to create a device that would allow users to interact with a computer in a more intuitive and efficient way.

The First Prototype

Engelbart’s first prototype was a wooden block with two metal wheels attached to the bottom. The wheels were positioned at a 90-degree angle to each other, allowing the device to move in any direction. The mouse was connected to the computer via a cord and was used to control the cursor on the screen. Engelbart also added a button on top of the mouse for clicking.

The Evolution of the Mouse

Over the years, the computer mouse has undergone many changes and improvements. In the 1970s, Xerox PARC (Palo Alto Research Center) developed a mouse with a single ball instead of two wheels, making it easier to use. In the 1980s, Apple introduced the first commercially successful mouse, which had a sleeker design and a single button. In the 1990s, the mouse became wireless, using infrared or radio frequency technology to connect to the computer.

The Impact of the Mouse

The invention of the computer mouse revolutionized the way we interact with computers. Before the mouse, users had to rely on keyboard commands to navigate through the computer, which was not very intuitive. The mouse made it easier for users to click on icons, scroll through documents, and move their cursor with precision. It also paved the way for the development of graphical user interfaces (GUIs), which are now the standard for operating systems.

The Legacy of Douglas Engelbart

Douglas Engelbart’s invention of the computer mouse has had a lasting impact on the world of technology. His work on human-computer interaction and the development of the mouse laid the foundation for future innovations in this field. In addition to the mouse, Engelbart also contributed to the development of hypertext, video conferencing, and other technologies that are still used today.


The computer mouse may seem like a simple device, but its invention was a significant milestone in the history of computing. Thanks to Douglas Engelbart’s ingenuity and vision, we now have a device that has become an essential tool for navigating the digital world. So the next time you click, scroll, or move your cursor with your mouse, remember the man behind this revolutionary device.
