Sadly, the early history of Western free reed instruments is somewhat cloudy, but if we are defining the harmonica as a mouth-blown free reed instrument where the notes of the scale are selected by the player's mouth, rather than fingers, the usual answer to this question is that it was invented by sixteen year old Christian Buschmann in 1821.
The mouse was invented by Douglas Engelbart in 1964 and consisted of a wooden shell, circuit board and two metal wheels that came into contact with the surface it was being used on. It was 8 years later in 1972 that Bill English developed the design further by inventing what is known as the Ball Mouse that we know today.
