The Chalcedon Foundation, which is named after a 451 A.D. council that proclaimed the state's subservience to God, was officially founded by Rousas John Rushdoony in summer 1965. In 1971, Gary North was hired part-time, and two years later North was hired full-time while Greg Bahnsen was also hired. Rushdoony founded Ross House Books in 1976, the same year in which North and Bahnsen left the Foundation to pursue careers elsewhere. In 1977, the Foundation's first office building was built. A decade later, the organization's "Newsletter" became a magazine, the "Chalcedon Report".
