Zimmerman's sudden death, shortly before the group's departure for the New World, Kelpius became the group's magister or leader. The travel diary of Kelpius has been preserved. Some of the forty or so who traveled with him aboard the Sarah Maria Hopewell were Heinrich Bernhard Koster, Daniel Falckner, and Johann Gottfried Seelig. They disembarked at Bohemia Landing, Maryland, and proceeded to Philadelphia and Germantown. On arrival in Philadelphia (which barely had 500 houses at this time) they moved to Germantown and then to the Wissahickon. There they established a regular program of private study and meditation. They eventually erected a large building for their meetings; some say they lived there communally, but others that they lived separately in caves and other rude shelters and cabins. They created a school for neighborhood children, held public worship services, and shared their medical knowledge. A few newcomers, including Conrad Matthai and Christopher Witt joined the group, but the community began to decline, especially after the death of Kelpius. Little is known of his death except for an account from years later which states that Kelpius had believed that he would not suffer physical death, but be translated to another existence. The same account suggests that Kelpius possessed the legendary philosopher's stone, which at his direction was cast into the Wissahickon or Schuylkill River shortly before he died near Germantown in 1708. His literary legacy is a collection of original hymns, a journal that includes many of his correspondences, and a book on prayer and meditation, A Short, Easy, and Comprehensive Method of Prayer, first published in English in 1761, and republished in 1951. A modern translation has been completed by Kirby Don Richards, A Method of Prayer. A Mystical Pamphlet from Colonial America. Richards' book includes both the German original and the new English translation. It also contains background materials that help explain the pamphlet and put it in its historical context. Kelpius was the subject of one of the first oil portraits in the thirteen British colonies; the painting was by Christopher Witt and was housed in the Historical Society of Pennsylvania, also home to Kelpius's journal, two collections of his original hymns, and other research source material. It's said to have been moved to the State Museum of PA located in Harrisburg. Music Kelpius was a musician, and he and his followers took with them instruments that became an integral part
