The Zsolnay factory in Pécs, Hungary, was founded by Miklós Zsolnay (1800–1880) in 1853 and led by his son, Vilmos Zsolnay (1828–1900) with chief designer Tádé Sikorski (1852–1940) to produce stoneware and other ceramics. In 1893, Zsolnay introduced porcelain pieces made of eosin. He led the factory to worldwide recognition by demonstrating its innovative products at world fairs and international exhibitions, including the 1873 World Fair in Vienna, then at the 1878 World Fair in Paris, where Zsolnay received a "Grand Prix". Frost-resisting Zsolnay building decorations were used in numerous buildings, specifically during the Art Nouveau movement.
