So was what Jobs took from Xerox the idea of the mouse? Not quite, because Xerox never owned the idea of the mouse. The PARC researchers got it from the computer scientist Douglas Engelbart, at Stanford Research Institute, fifteen minutes away on the other side of the university campus.

His mouse was a bulky, rectangular affair, with what looked like steel roller-skate wheels.
