Jan Zach, called in German Johann Zach (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 complex and eccentric personality led to numerous conflicts and lack of steady employment .
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 but he was suspended from his position in 1750 and finally dismissed in 1756. From that point on it appears that Zach never again had steady employment.

He traveled through Europe and supported himself financially by performing and selling copies of his works, teaching, dedicating his compositions, and so on. He visited numerous courts and monasteries in Germany and Austria, stayed in Italy in 1767 and between 1771 and 1772, and may have worked as choirmaster at the Pairis Abbey in Alsace.

Only a few of Zach's pieces were published during his lifetime. Toward the end of his life, Zach gave numerous compositions to the monks at the Cistercian monastery at Stams. These manuscripts comprise the largest repository of Zach's works in the world.
