Jan Zach
Jan Zach, called in German Johann Zach (baptized 13 November 1699 – 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.
Life
Zach was born in Čelákovice, Bohemia into a wheelwright's family. In 1724 he moved to Prague and started working as violinist at St Gallus and at St Martín. According to Dlabacž, he studied organ under Bohuslav Matěj Černohorský, who lived in Prague from 1720 to 1727. Zach's career as organist started at St Martín, and by 1737 he was also playing the organ at the monastic church of the Merciful Brethren and the Minorite chapel of St Ann. In 1737 he competed for the position of organist at St. Vitus Cathedral, but was not successful. Details of what happened next are unknown: he was reported to have left Bohemia, but apparently remained in Prague at least until 1740. By early 1745 he was living in Augsburg and then on 24 April 1745 he was appointed Kapellmeister of the Electoral orchestra at the court of Johann Friedrich Karl von Ostein, Prince-Elector of Mainz. He visited Italy in 1746 and, briefly, Bohemia in 1747.
