Cyrill Demian (Arm. Կյուրեղ Դեմյան) (1772–1849) was an Armenian inventor of Armenopolis origin who made his living as an organ and piano maker with his two sons, Karl and Guido, in Mariahilfer Straße No. 43 in Vienna, Austria. On May 6, 1829, Cyrill and his sons presented a new instrument to the authorities for patent - the accordion. The patent was officially granted on May 23, 1829.
