Jiří Čart (German: Georg Czarth, Zarth, Czard, Szarth, Tzarth, or Zardt;[1] 8 April 1708 – c. 1780) was a Bohemian composer, violinist and flautist of the late baroque period.
In Vienna he received violin instruction from the Royal Court musicians Franz Josef Timmer and Johann Otto Rosetter (1690–1752); and from Biarelli he learned the flute.
After being joined in Breslau (today Wrocław) by the violinist Carl Höckh and the hornist Wilhelm Weidner they searched for better employment opportunities in Poland.
In 1734, following the death of August II and the dissolution of the Polish Chapel, Czarth and Benda entered into the service of the crown prince Friedrich of Prussia in Ruppin and a year later in Rheinsberg.
Upon the ascent of Friedrich to the throne of Prussia in 1740, the two musicians were transferred to Berlin, where they were employed in the newly founded Court Orchestra.
