Herbert W. Armstrong, American evangelist and publisher, founded Worldwide Church of God (d. 1986)
Herbert W. Armstrong (July 31, 1892 – January 16, 1986) 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.

Armstrong's teachings required observance of parts of the Mosaic Law including seventh-day Sabbath, dietary prohibitions, and the covenant law "Holy Days". He also proclaimed that behind contemporary world events loomed various Biblical prophecies, interpreted in light of British Israelism. As founder and head of the Ambassador International Cultural Foundation, Armstrong and his advisers met with heads of governments in various nations, for which he described himself as an "ambassador without portfolio for world peace."
