The trackball was invented by Tom Cranston, Fred Longstaff and Kenyon Taylor working on the Royal Canadian Navy's DATAR project in 1952. It used a standard Canadian five-pin bowling ball. It was not patented, as it was a secret military project.
Independently, Douglas Engelbart at the Stanford Research Institute invented the first mouse prototype in 1963 with the assistance of his colleague Bill English. Engelbart never received any royalties for it, as his patent ran out before it became widely used in personal computers.
