aerophone (11. 577)

Officially recognised and granted a patent for his invention on this day in 1829, Armenian extract working in Vienna the accordion (from the German Akkord for concord of sounds) of Cyrill Demian (Կյուրեղ Դեմյան) and sons was only half of modern version with bellows and a single button board but was considered distinct enough for court authorities from the portable klezmers and harmonicas available for vocal accompaniment. Numerous variations followed and there is some debate amongst historians who credit Friedrichroda native Christian Friedrich Ludwig Buschman with the innovation but the accordion of Demian’s was clearly based on a common prototype called the Handäoline with a lot of competing models being introduced at the time (see also), and Garfield’s dad Jon, an attested aficionado, states in the comic strip that Demian is his hero, making it cannon.
