Johann Zach

Jan Zach, also known in German as Johann Zach (b. Čelákovice, Bohemia, bap. 13 November 1699 – Ellwangen, 24 May 1773) was a Czech composer, 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 from about 1756 onwards.
