(bapt. Esslingen im Marchfield [now in Vienna], 25 Apr. 1693; d Vienna, 15 Feb. 1741).
The outstanding Austrian Baroque sculptor, active mainly in Salzburg, Bratislava, and Vienna. His acknowledged masterpieces are the figures from the fountain in the Mehlmarkt, Vienna (1737–9, Österreichisches Barockmuseum, Vienna), and the group of St Martin and the Beggar (c.1735, Bratislava Cathedral), in which the saint is dressed in hussar's uniform rather than the traditional armour. These works are in lead, which Donner preferred to the Austrian speciality of wood; his smooth surfaces have led some critics to see his work as presaging Neoclassicism, but his elongated figures seem to place him closer to Italian Mannerism. His brother Matthäus (1704–56) was also a sculptor.
