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 diatonic harmonica is made to play in one key and is easier to learn but you will need to buy more than one. The guitar's natural key is E; so buying a diatonic harmonica in the key of E major would be ideal. The other diatonic harmonicas you should aim to add to your collection is G major and C major. Diatonic harmonicas are cheap and it shouldn't take long before you have a collection of harmonicas that cover every key.
