Philosopher's stone
Müller wrote to the Harmony Society (and other communes in the United States as well as numerous leaders in Europe) in 1829 proclaiming himself to be the "Lion of Judah" and a prophet in possession of the Philosopher's stone. As well as giving himself numerous fictitious names and titles, like Count de Leon, Archduke Maximilian von Este, and Proli, he claimed that he and his followers were the true Philadelphians and were ready to make a home for themselves with the Harmonites in Old Economy, Pennsylvania. The Harmonites, being religious searchers looking for a hopeful sign, and eager to justify their own religious prophesies, agreed to the visit, and in 1831, Müller arrived with his entourage of forty people (including a Dr. Göntgen.) Soon, Müller and the Harmony Society's leader, George Rapp, grew tired of each other and began to argue. Sensing the dissatisfaction that some Harmonites were feeling towards the Society's custom of celibacy, Müller was able to use that to his advantage and get about a third of the Harmonites to be on his side in the ensuing argument. However, the majority of the Society decided to keep George Rapp as their leader. In the end, a settlement was reached with the dissenters, and all who wished to leave the Harmony Society during the schism were given $105,000 as a group.
