The 1st Computer Rodent

In 1964, Dr. Douglas Engelbart received a patent for a device consisting of a wooden shell and two metal wheels - the computer mouse. In 1970, a patent was awarded (out of more than 45 for Dr. Englebart) for what was described in the patent application as an "X-Y position indicator for a display system." He nicknamed it the "mouse" because the tail came out the end.
