(b. 1703, Augsburg, d. 1761, Wien)
German draughtsman and engraver. He was trained in Augsburg by Johann August Corvinus (1683-1738). In 1721 he drew a series of city views of Vienna, which were later (1724-25) reproduced as engravings in Viennese collections. In 1722-23 Kleiner worked for the imperial vice-chancellor Friedrich Karl von Schönborn, drawing the Schönborn family buildings in Austria for a large collection of engravings. From 1723 he worked for Lothar Franz von Schönborn, sketching the Schönborn palaces in Franconia; other work in the region included engraved designs for altars in Bamberg churches and in Dettelbach am Main.
