On 9 December 1968 hi-tech visionary Douglas Engelbart first used one to demonstrate novel ways of working with computers. The first mouse that Dr Engelbart used in the demo at the Fall Joint Computer Conference (FJCC) was made of wood and had one button.
There will be a party.
A day of celebration is planned in California to mark the 40th anniversary; with many of the researchers behind the original demo reunited to mark the event.
