Johann Michael Graff

Johann Michael Graff, was a German Rococo sculptor and plasterer. Among his most celebrated decorations are those at Schönhausen Palace, Germany, and Rundāle Palace, Latvia.
Graff came from a family of stucco decorators from Bavaria who were members of the so-called Wessobrunner School. He seems to have moved to Brandenburg at some point, where he was influenced by the decorative style predominant in and around Berlin. He very probably made decorations for Schönhausen Palace before being hired by the Duke of Courland, Peter von Biron, to decorate his residences in present-day Latvia. He is known to have decorated Jelgava Palace and Rundāle Palace for the Duke. In present-day Estonia, he also made lavish stucco decorations for Põltsamaa Castle, and possibly at Kabala Manor.
