During the early 18th century, German manufacturer Meissen became the first producers of hard-paste porcelain in Europe. The white porcelain was developed by Ehrenfried Walther von Tschirnhaus, a German mathematician and physiscist; production began in 1710 and continues today. Throughout its extensive history, Meissen has worked closely with artists, sculptors and painters to create the shapes, glazes and patterns that have contributed to the company's success. Some of the most notable modellers, sculptors and potters include Johan Joachim Kaendler, Michel-Victor Acier and Erich Hösel. Over the last four centuries, Meissen has produced a number of notable wares, such as 'Schwanenservice' ('Swan Service'), created between 1737 and 1742 for the Saxon-Polish statesman, Heinrich von Brühl. The 'Blue Onion' pattern was originally designed in the 18th century, inspired by a Chinese bowl from the Kangxi-period. Other popular patterns include the 'Court Dragon' and 'Red Dragon', also influenced by Chinese porcleain. Some of these notable designs remain in production today, such as the 'Purple Rose' and the 'Vine-Leaf'. As well as wares, Meissen has also been recognised for its fine porcelain figurines, which are sought-after on the collectors' market.
