Frederick Reichert, Rapp’s adopted son, organized the relocation of Rapp's followers from Württemberg to Pennsylvania in 1804 and supervised the immigration of other Rappites to the United States. Reichert, who became known as Frederick Rapp, was the business leader and public spokesman for the Harmony Society, drew up the town plan for its new village at New Harmony, Indiana, in 1814, and served as one of the delegates to the Indiana Territory's Constitutional Convention in 1816. Frederick Rapp also helped choose the site for the permanent seat of government of Indiana in 1820 that was later named Indianapolis and held leadership roles in several Indiana banks. After the Harmonists sold their Indiana land in 1824, he relocated with other members of the Society to Economy, Pennsylvania, where he died in 1834.
