Who invented mouse

A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer.
The first computer mouse was publicly unveiled in 1968 by its inventor, Douglas C. Engelbart. He invented the computer mouse in 1964 — two decades before it would ship with the first Apple Macintosh.
