Jacob A. O. Preus Jr., son of soon-to-be Governor Preus Sr., is born in St. Paul. After becoming president of the Lutheran Church–Missouri Synod in 1969, he, along with other advocates of traditionalism, would be troubled by alleged liberalism in the faculty at Concordia Seminary in St. Louis and their attitude toward biblical authority. A crucial struggle about doctrinal purity would ensue, with Preus successfully being re-elected president in 1973 and thus securing the traditional ways of the synod.
