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.
Harmonicas come in a variety of keys (click here for more about harmonica keys and note names). The most common harmonica key is C, the notes on a C harmonica are shown below. In the diagram blow means the note when blowing into a hole, draw means the note when breathing in.
