Czech composer (baptized 13 November 1699, Čelákovice, presently Czechia – 24 May 1773, Ellwangen, presently Germany), violinist and organist. Although he was a gifted and versatile composer capable of writing both in Baroque and Classical idioms, his eccentric personality led to numerous conflicts and lack of steady employment since about 1756. He wrote 33 masses, 3 requiems, 10 offertories and various arias, hymns, motets and vespers settings.
