On this day in 1829 a patent for an Accordion is granted to Cyrill Demian in Vienna.
In the official patent, it was described as:
Its appearance essentially consists of a little box with feathers of metal plates and bellows fixed to it, in such a way that it can easily be carried, and therefore traveling visitors to the country will appreciate the instrument. It is possible to perform marches, arias, melodies, even by an amateur of music with little practice, and to play the loveliest and most pleasant chords of 3, 4, 5 etc. voices after instruction.
