Johann Georg Rapp (November 1, 1757 in Iptingen, Germany – August 7, 1847 in Economy, Pennsylvania) was the founder of the religious sect called Harmonists, Harmonites, Rappites, or the Harmony Society. Born in Iptingen, Duchy of Württemberg, Germany, Rapp became inspired by the philosophies of Jakob Böhme, Philipp Jakob Spener, and Emanuel Swedenborg, among others. In the 1780s, George Rapp began preaching and soon started to gather a group of his own followers.
