Apollonicon
The Apollonicon was presented to the public the first time in 1817 built by the English Organ builders Flight & Robson in London. It was an automatic playing machine with about 1'900 pipes and 45 organ stops with a technic familiar to the barrel organ. It was inspired by Johann Nepomuk Mälzels Panharmonikon. It also had five keyboards, one of them used as the pedal keyboard, so the instrument could be played by a few persons in manual mode as well.
