Herbert W. Armstrong, American evangelist and publisher, founded Worldwide Church of God (died 1986)

Herbert W. Armstrong was an American evangelist who founded the Worldwide Church of God (WCG). An early pioneer of radio and television evangelism, Armstrong preached what he claimed was the comprehensive combination of doctrines in the entire Bible, in the light of the New Covenant scriptures, which he maintained to be the restored true Gospel. These doctrines and teachings have been referred to as Armstrongism by non-adherents.
