The Panharmonicon was a musical instrument invented in 1805 by Johann Nepomuk Mälzel, a contemporary and friend of Beethoven. Beethoven apparently composed his piece "Wellington's Victory" (Op. 91) to be played on this behemoth mechanical orchestral organ to commemorate Arthur Wellesley's victory over the French at the Battle of Vitoria in 1813. It was one of the first automatic playing machines, similar to the later Orchestrion.
The Panharmonicon could imitate all instruments and sound effects like gunfire and cannon shots. One instrument was destroyed in the Landesgewerbemuseum in Stuttgart during an air raid in World War II.
One of Mälzel's Panharmonicons was sent to Boston 1811 and was exhibited there and then in New York City and other cities. Mälzel also was on tour with interruptions with this instrument in the USA from February 7, 1826 until his death in 1838.
