Stuwer, Viennese family of pyrotechnists in the 18th and 19th centuries. Johann Georg S. from Ingolstadt held his first firework display in the Prater park in Vienna on May 27, 1774. Was followed by his son Caspar S. (d. Feb. 10, 1819) in 1799. Caspar's son Anton S. (d. Jan. 5, 1858) brought Viennese pyrotechnics to perfection. Anton S. the Younger had to give way to the Great Exhibition of 1873 and left Vienna for good in 1876 after one last spectacular firework display.
