The computer mouse was invented by the pioneer Douglas Engelbart at the Stanford Research Institute. He invented the first mouse prototype in 1963 with the assistance of his colleague Bill English.
The mouse was made by wood having wheels that make contact with the working surface. The mouse had a cord attached to the rear part of the device looking like a tail and generally resembling the common mouse. The trackball, a related pointing device, was invented independently by Tom Cranston, Fred Longstaff and Kenyon Taylor working on the Royal Canadian Navy's DATAR project in 1952. This trackball was not used in the mouse invented by Douglas Engelbart but later modification make this ball as a part of mouse.

In 1968, A German company Telefunken developed and published a mouse that had a ball and reversed mouse cord. This design is available until today. Telefunken's mouse was then sold commercially as optional equipment for their TR-440 computer, which was first marketed in 1968. Telefunken did not apply for a patent on their device.
Douglas Engelbart is an American inventor, is known for his work on the challenges of human-computer interaction, resulting in the invention of the computer mouse and the development of hypertext, networked computers, and precursors to GUIs. The invention of the mouse was just a small part of Engelbart's much larger project, aimed at augmenting human intellect. He never received any royalties for the invention of computer mouse.
