Rosicrucianism rose to considerable prominence in Europe during the 17th century following the publication and wide circulation of a small pamphlet, the "Fama Fraternitatis". AMORC scholars have suggested that Rosicrucians first went to America in the area of present-day Carmel-by-the-Sea, California in The Vizcaíno Expedition of 1602–1603. The next Rosicrucian expedition to America is said to have been by the chartered vessel "Sarah Maria" during the early months of 1694, under the leadership of Grand Master Johannes Kelpius, and a colony was established in what is now Fairmount Park, Philadelphia. They finally settled on the banks of the Wissahickon. "In that retired valley beside the flowing brook the secret rites and mysteries of the true Rosicrucian Philosophy flourished unmolested for years, until the state of affairs brought about by the American Revolution, together with pernicious Sunday legislation which also discriminated against the keepers of the scriptural Sabbath day, gradually caused the incoming generation to assimilate with the secular congregations." That is disputed by another organization, the Fraternity of the Rosy Cross, at one time headed by Dr. R. Swinburne Clymer. Johannes Kelpius, of the Jacob Boehme Lodge in Germany, allegedly led the German Pietists to America, although no historical evidence exists to support that claim, nor the common claim to be connected to the Ephrata Cloister. The two rival organizations have long disputed each other's claims to Rosicrucian genuineness.
