Answer:
The computer mouse was invented by American Douglas C Engelbart, born on 30 January 1925, in collaboration with William English.
The first prototype computer mouse was made to use with a graphical user interface, in 1964. Engelbart's computer mouse was patented on 17 November 1970, under the name "X-Y Position Indicator For A Display System". It was called a mouse because of its tail-like cable, but in reality it was just a hollowed-out wooden block with two metal wheels and a single push button on top.
The first computer mouse was designed to select text, move it around and similarly manipulate it. Engelbart's invention was significant for how it changed the way computers worked. Originally, computers had been little more than specialised machinery that only trained scientists could use, but the invention of the mouse enabled it to become a user-friendly tool that almost anyone could use.
The computer mouse was demonstrated for the first time on 9 December 1968, after being developed at the Stanford Research Institute in Menlo Park.
