Czech composer (November 27, 1759, Kamenice u Jihlavy, Czechia – January 8, 1831, Vienna, Austria) of classicist era. His output was prolific, with at least three hundred published compositions in at least 110 opus numbers including at least five symphonies, seventy string quartets and many others for winds and strings, about fifteen string quintets and much music for winds by themselves and with other instruments, for which he has perhaps become best-known.
