Fraternitas Rosae Crucis (Fraternity of the Rosy Cross or FRC) is a Rosicrucian fraternal organization founded by Paschal Beverly Randolph in 1858, and is the oldest Rosicrucian Order in the US. They also operate Beverly Hall corporation and the Clymer Health Center in nearby Quakertown, Pennsylvania.
It claims to be the "authentic Rosicrucian Fraternity that was first instituted in Germany in 1614".
The FRC's first lodge was established in San Francisco in 1861, and closed soon after. In 1871 they established another lodge in Boston and in 1874, reestablished in San Francisco. In 1875 they finally settled in Philadelphia.
While Clymer headed the order, the FRC established itself at Beverly Hall, in Quakertown, Pa.
