The computer mouse as we know it today was invented and developed by Douglas Engelbart, with the assistance of Bill English, during the 1960's and was patented on November 17, 1970. While creating the mouse, Douglas was working at the Stanford Research Institute, a think tank sponsored by Stanford University.
Early Prototypes. Before Engelbart developed the mouse, the trackball had already been invented. In 1954, the Canadian Navy created the device for utilization on the DATAR system. The mouse Engelbart made was large and had two wheels. Although he invented the mouse in 1965, he only patented it in 1970. He called the device an XY Position Indicator for a Display System. The basic idea was actually inspired by the telautograph which was designed back in the 19th century. A couple of years later (1972) Bill English created the ball mouse.
